Show all unowned disks
4
FAS1> disk assign 0b.43 0b.41
Assigns the listed unowned disks to FAS1
5
FAS1> disk assign 2a.*
Assigns all unowned disks connected to the 2a adapter interface to FAS1
6
FAS1> disk assign all Warning: Use with caution. Not restricted by A and B loop in clusters

on
Specifies if disks are auto assigned to a controller. Occurs within 10 minutes of disk insertion.
1.1.2 Aggregates
Create an aggregate of physical disks to store Flexible Volumes. See the matrix below for the maximum number of disks an aggregate can use based on disk size and ONTAP version. Step Command/Action Description
1
FAS1> aggr status –s
View all available spare disks
2
FAS1> aggr create aggr03 -t raid_dp -r 14 9

FAS1> aggr add aggr0 –d 7a.17 7a.26
Add disks 7a.17 and 7a.26 to aggr0. They will be added to the last RAID group created (if it is incomplete) or will create a new RAID group
FAS1> aggr add aggr0 4@272 –f –g rg1
Add four 300GB disks to aggr0 by adding them to RAID group number 1 Note: See disk size matrix below for size values
5
FAS1> snap delete –A –a aggr0
Delete aggregate snapshots to allow reallocate access to all data blocks
6
FAS1> reallocate on

Run reallocate –f on all volumes in the aggregate to redistribute them across the new drives
8
FAS1> reallocate start –A –o aggr0
Start a one-time reallocate of free space in the aggregate (does not reallocate data in the volumes)
1.1.2.2 Disk right-size and max disk per aggregate matrix
Use these values when creating an aggregate and when adding disks using n@size The max size numbers include the parity and diagonal-parity drives. Optimal RAID group sizes indicate what value to use for the raidsize option to use the least amount of parity drives, have the most data disks, and not harm performance by creating short raid groups (# of raid groups@raidsize value).

Turn on Unicode for CIFS and SAN
4
FAS1> vol options vol01 convert_ucode on
Turn on conversion to Unicode for any files copies into the volume
5
FAS1> qtree security vol01 nfs
The security style is inherited from the root volume. Change it if the new volume will use a different security style
-
FAS1> aggr status aggr05 –i

1.1.4.3 Prioritize volume I/O with FlexShare
FlexShare is built into ONTAP for prioritizing system resources for volumes. If you assign a priority to one volume, you should assign a priority to all volumes. Any volumes without a priority are assigned to the default queue where they share the same resources. This can degrade their performance. Step Command/Action Description
1
FAS1> priority on FAS2> priority on
Enables FlexShare. Both nodes of an HA cluster must enable FlexShare even if only one uses it
2
FAS1> priority set volume dbvol level=VeryHigh system=30
dbvol is given the highest priority and system operations (e.g, SnapMirror) are selected over user operations 30% of the time
3
FAS1> priority set volume dbvol cache=keep
Instruct ONTAP to retain data in the buffer cache from dbvol as long as possible
4
FAS1> priority set volume db_logs cache=reuse
Instruct ONTAP to quickly flush data in the buffer cache from db_logs
5
FAS1> priority show volume user_vol03
Display the priority assigned to user_vol03
6
FAS1> priority set volume testvol1 service=off
Temporarily disable priority on testvol1 and places it into the default queu

create_ucode
off
Force UNICODE character use on/off when files are created. Turn on for SnapMirror and SnapVault volumes
guarantee
volume
Volume setting preallocates disk space for entire volume. File only allocates space for space reserved files and LUNs in the volume. None means no disk space is guaranteed
minra
off
When on, turns speculative file read-ahead OFF and may reduce performance.
no_atime_update

When on, prevents update of access time in inode when a file is read, possibly increasing performance. Use with caution.
nosnap
off
When on, disables automatic snapshots of the volume
nosnapdir
off
When on, disables the .snapshot directory for NFS
root
N/A
Designates the volume as the root volume.
1.1.5 SnapLock volumes
SnapLock volumes are special volumes (WORM) which turn the files inside to read-only and can not be edited or deleted until a user defined retention period has expired. Read the documentation before creating or altering SnapLock volumes. Not all versions of Data ONTAP support SnapLock volumes. Step Command/Action Description
1
FAS1> aggr create aggr_name -L <compliance | enterprise> -t raid_dp [other aggr create options]
NOTE: ALL volumes in this aggregate will be SnapLock volumes by default and inherit the aggregate‟s SnapLock attributes.

2 NAS Implementation
This section describes procedures to access data using NFS or CIFS. Data can also be accessed using HTTP or FTP protocols, but will not be covered in this guide. Refer to the Data ONTAP File Access and Protocols Management Guide for more information.
2.1 NFS exports
Step 1. On FAS controller: Create new NFS export: Step Command/Action Description
1
FAS1> license add <code>
Install license for NFS protocol
2
FAS1> qtree security /vol/flex2 unix
Configure qtree security settings on volume to be exported. Only a concern on systems also licensed for CIFS
3
FAS1> exportfs -i -o rw,root=adminhost /vol/flex2
Immediately create export.
4
FAS1> exportfs –p /vol/flex1
Make export persistent by adding to /etc/exports file. Note: By default, all newly created volumes are added to /etc/exports – even on CIFS only systems
OR
Edit /etc/exports with a text editor FAS1> exportfs -a
Activate all entries in edited /etc/exports file
5
FAS1> exportfs –q /vol/flex1/qtree1
Displays the export options. This can be faster than using rdfile on systems with a long /etc/exports file
6
FAS1> exportfs –u /vol/flex1/qtree1
Unexport /vol/flex1/qtree1 but leave its entry in the /etc/exports file
7
FAS1> exportfs –z /vol/flex1/qtree3
Unexport /vol/flex1/qtree3 and disable the entry in /etc/exports
Note: The implementation of NFS in Data ONTAP performs reverse DNS lookups for all hosts trying to access NFS exports. Hosts without a reverse address in DNS will be denied access. Step 2. On UNIX/Linux Server: Create new mount point and mount export: Step Command/Action Description
1
# showmount -e FAS2
Verify available mounts on FAS2
2
# mkdir /mnt/FAS2/unix_vol
Create a mount point
3
# mount FAS2:/vol/flex2 /mnt/NA-2/unix_vol
Mount the Unix export from FAS2.
4
# cd /mnt/FAS2/unix_vol
Change to new mount point
5
# ls -al
Verify mount was successful
6
Add mount command and options to /etc/vfstab (Solaris) or /etc/fstab (HP-UX, Linux)
Make mount persistent
Note: If you change the name of the exported volume or qtree you must update the /etc/fstab or /etc/vfstab file on the host. Data Ontap will automatically modify the /etc/exports entry.

5 Space Management
5.1 Managing Volume Free Space
Refer to the Data ONTAP System Management Guide for more information.
5.1.1 Volume Space Management Settings Step Command/Action Description
1
FAS1> vol options vm_luns guarantee volume
„Volume‟ space guarantee is the default and ensures blocks are preallocated for the entire volume.
FAS1> vol options vm_luns fractional_reserve 65
FlexVols containing space-reserved LUNs and use the „volume‟ guarantee can set the fractional reserve to less than 100%.
2
FAS1> vol options oradb_vol guarantee file
„File‟ guarantee only preallocates blocks for space-reserved files (i.e., LUN and database files). May lead to out-of-space errors in the containing aggregate.
FAS1> file reservation /vol/db02/lun1.lun enable
Turn on space-reservation for the LUN
3
FAS1> vol options log_vol guarantee none
„None‟ allocates blocks as data is written and may lead to out-of-space errors. This is also known as Thin Provisioning. Refer to TR-3563 for more information: http://media.netapp.com/documents/tr-3563.pdf
Warning: When you take a FlexVol volume offline, it releases its allocation of storage space in its containing aggregate. Other volumes can then use this space which may prevent the volume from coming back online since the aggregate can no longer honor the space guarantee.
5.1.2 FPolicy
FPolicy performs file screening which is like a firewall for files. FPolicy works with CIFS and NFS to restrict user-defined file types from being stored on the system. FPolicy can perform basic file blocking natively or work with third-party file screening software. Refer to the Data ONTAP File Access and Protocols Management Guide for more information.
Note: Antivirus scans bypass FPolicy and can open and scan files that have been blocked. Step Command/Action Description
1
FAS1> license add <CIFS code> FAS1> license add <NFS code>
FPolicy requires a CIFS license to operate, even in NFS environments
2
FAS1> options fpolicy.enable on
Turn on the fpolicy engine
3
FAS1> fpolicy create music_files screen
Create a policy named music_files and set it to a policy type of „screen‟
4
FAS1> fpolicy
Display all policies and their status
Data ONTAP 7G Cook Book
Data ONTAP 7G Cook Book v3_1.doc Page 33
17 August 2010 © NetApp
Data ONTAP Cook Book v3.1
5
FAS1> fpolicy extensions include add music_files mp3,ogg,mid
Adds files with these filename extensions to the policy, restricting them from being stored or modified
6
FAS1> fpolicy extensions exclude add music_files wav
Ignores .wav files during screening. Warning: Creating an exclude list causes all file types not excluded to be screened as if they were part of an include list
7
FAS1> fpolicy extensions include remove music_files mid,???
Removes .mid files and the default ??? extension wildcard from the include list
8
FAS1> fpolicy extensions include show music_files
Show the list of file extensions on the include list
9
FAS1> fpolicy options music_files required on
Requires all files being accessed to be screened by the policy before access is granted. Note: If no third-party file screening server is available, screening reverts to native file blocking
10
FAS1> fpolicy monitor set music_files –p cifs,nfs create,rename
Instructs the policy to activate when files are created or renamed. This example will prevent files from being copied and then renamed to avoid file screening
11
FAS1> fpolicy enable music_files
Activates the policy to begin file screening
12
FAS1> fpolicy volume include add music_files users_vol
Apply music_files policy only to users_vol volume rather than all volumes
13
FAS1> fpolicy volume exclude add music_files rootvol
Do not screen the rootvol volume. Warning: Creating an exclude list causes all volumes not excluded to be screened as if they were part of an include list
14
FAS1> fpolicy disable music_files FAS1> fpolicy destroy music_files
Disable and delete the music_files policy
5.1.3 Reallocate
Reallocation is like a filesystem defrag – it optimizes the block layout of files, LUNs, and volumes to increase performance.
NOTE: Snapshots created before the reallocate hold onto unoptimized blocks and consume space. In most cases, NetApp recommends deleting snapshots before initializing the reallocate process
Warning: Do not use reallocate on deduplicated volumes. Reallocate the SnapMirror source volume rather than the destination. Step Command/Action Description
1
FAS1> reallocate on
Turn on the reallocation process on the storage controller.
2
FAS1> vol options oradb03 guarantee=volume
Set the space guarantee to „volume‟ to ensure reallocate does no t create an overcommitment issue in the aggregate
Data ONTAP 7G Cook Book
Data ONTAP 7G Cook Book v3_1.doc Page 34
17 August 2010 © NetApp
Data ONTAP Cook Book v3.1
3
FAS1> snap list oradb3
Snapshots lock blocks in place so delete unneeded snapshots for better results
4
FAS1> reallocate start /vol/oradb03
Enable reallocation on the oradb03 volume. now reallocate will run on the volume every day at midnight (see step 3)
FAS1> reallocate start –p /vol/oradb03
Run reallocate, but do not change logical layout so snapshots may be preserved. Warning: This will degrade performance when reading old, unoptimized snapshots (e.g,. SnapRestores and using cloned LUNs and volumes).
FAS1> reallocate start –A –o aggr03
Reallocate free space in aggr03. This will not move data blocks
5
FAS1> reallocate schedule -s "0 23 * 6" /vol/db/lun1
Run reallocate on the LUN every Saturday at 11 PM.
6
FAS1> reallocate status [ pathname ]
Display status of reallocation jobs for entire system or specified pathname.
7
FAS1> reallocate stop /vol/exchdb/lun2.lun
Delete a reallocate job.
The read_realloc volume option is not part of the reallocation command but uses many of the same system processes to perform a similar function to defragment files read sequentially. Note: Files in a volume are defragmented only after they have been read into memory once and determined to be fragmented. Not all files will be reallocated and volumes with small files and mostly random reads may not see any benefit. Step Command/Action Description
1
FAS1> vol options testvol read_realloc on
Turn on file read reallocation . Use on volumes with few snapshots because it may duplicate blocks and consume space
2
FAS1> vol options VM_vol05 read_realloc space_optimized
Turn on file read reallocation but save space by not reallocating files in snapshots. This will reduce read performance when reading files in a snapshot (during file restore or using FlexClone volumes)
5.1.4 Managing inodes
Inodes determine how many 4KB „files‟ a volume can hold. Volumes with many small files and volumes larger than 1TB can run out of inodes before they run out of free space.
Warning: Inodes consume disk space and system memory. They can only be increased so make small changes. Step Command/Action Description
1
FAS1> df –i users_vol
Display inode usage in the users_vol volume.

2
FAS1> maxfiles users_vol
Display current maximum number of files as well as number of files present in the volume.
3
FAS1> maxfiles users_vol
Increase the number of inodes (increase by number divisible by 4).
5.1.5 Automatic Space Preservation (vol_autogrow, snap autodelete)
Data ONTAP can automatically make free space available when a FlexVol volume reaches 98% full by growing the volume and/or deleting snapshots. One or both options can be configured on a volume. Note: These options are not recommended on volumes smaller than 100GB because the volume may fill up before the triggers execute. Step Command/Action Description
1
FAS1> vol options vol17 try_first volume_grow
When vol17 fills up ONTAP will try to grow the volume before deleting snapshots. This is the default.
FAS1> vol options vol17 try_first snap_delete
ONTAP will try to delete snapshots before growing the volume.
2
FAS1> vol autosize vol17 on
Turn space preservation on using default settings. The volume will grow to 120% of original size in increments of 5% of the original volume size.
FAS1> vol size apps_vol FAS1> vol autosize apps_vol –m 50g –i 500m on
Check size of volume then set maximum volume size to 50GB and grow by 500MB increments
3
FAS1> vol autosize apps_vol
View the autogrow maximum size and increment settings
[7.3] FAS1> vol status –v apps_vol
View the autogrow maximum size and increment settings
4
FAS1> snap autodelete vol17 show FAS1> snap autodelete vol17 on
View current settings then enable snapshot autodelete
5
FAS1> snap autodelete vol17 commitment [ try | disrupt ]
The default, try only permits snapshots not locked by data protection utilities (mirroring, NDMPcopy) AND data backing functionalities (volume and LUN clones) to be deleted. disrupt only permits snapshots not locked by data backing functionalities (volume and LUN clones) to be deleted.
6
FAS1> snap autodelete vol17 trigger volume
The default, volume triggers snapshot delete when the volume reaches 98% full AND the snap reserve is full.
FAS1> snap autodelete vol17 trigger snap_reserve
snap_reserve triggers snapshot delete when the snap reserve reaches 98%.
Data ONTAP 7G Cook Book
Data ONTAP 7G Cook Book v3_1.doc Page 36
17 August 2010 © NetApp
Data ONTAP Cook Book v3.1
7
FAS1> snap autodelete vol17 target_free_space 10
Stop deleting snapshots when either volume or snap_reserve (determined by the „trigger‟ setting) reaches 10%. Default setting is 20%.
8
FAS1> snap autodelete vol17 delete order [ newest_first | oldest_first ]
The default is to delete oldest snapshots first.
8
FAS1> snap autodelete vol17 defer_delete [ scheduled | user_created ]
By default, user_created (manual or script created snapshots - including SnapDrive, SnapMirror, and SnapVault) are deleted last. If set to scheduled then snapshots created by snap sched are deleted last.
5.2 Deduplication
Deduplication is a form of compression that looks for identical data blocks in a volume and deletes duplicates blocks by adding reference counters in the metadata of a few „master‟ blocks. Read TR-3505 for detailed information: http://media.netapp.com/documents/tr-3505.pdf
Note: NDMP copies and backups, SnapVault and Qtree SnapMirror decompress or “rehydrate” the data which will consume space on the destination tape or disk system.
Warning: Each storage controller model has a volume size limit and limit on how much non-duplicate and deduplicated data those volumes can hold. Check the matrix in TR-3505 for your systems‟ limits. Data ONTAP 7.2 requires 1 -6% free volume space to hold the deduplication metadata. Data ONTAP 7.3.x moves most of the metadata into the aggregate and requires 2% volume free space and 4% aggregate free space (if you have set aggregate snap reserve below 4%, you may need to increase it). Step Command/Action Description
1
FAS1> license add <code>
Add licenses for A_SIS and Nearstore to use deduplication.
2
FAS1> sis on /vol/group_vol
Enable duplication on specified volume.
3
FAS1> sis start –s /vol/group_vol
Start a scan of the volume and then run every day at midnight.
4
FAS1> sis config /vol/group_vol
Display the schedules of SIS enabled volumes.
5
FAS1> sis config –s /vol/group_vol wed, sat@03
Schedule deduplication scan every Wednesday and Saturday at 3 AM. Note: Stagger schedules because an HA cluster can only support 8 concurrent deduplication operations.
FAS1> sis config –s auto@35 /vol/vol01
No schedule. Run deduplication scans run when new or changed blocks changed since last scan exceed 35% of total deduplicated blocks. Without a number, the default for auto is 20%
6
FAS1> sis status
Display status of all SIS enabled volumes.

Data ONTAP Cook Book v3.1
7
FAS1> df –s
Display space savings generated by SIS operations.
8
FAS1> sis stop /vol/temp_vol
Abort the currently active SIS operation.
9
FAS1> options cifs.snapshot_file_folding.enable on
This option reduces the duplication of blocks from temp files (which are a copy-on-save process) in CIFS volumes. File folding compares blocks in the active file (temp file) with blocks in snapshot copies of the file and re-uses common blocks. There is a small trade-off between performance and space utilization. If the folding process begins to consume memory, it is suspended until later.
5.2.1 [7.3] Maximum volume deduplication limits
The maximum volume size is the same for 32-bit and 64-bit volumes. Model max vol size WITHOUT dedupe (TB) 7.3 max deduped size (TB) 7.3 Deduped data size (TB) 7.3 max vol size WITHOUT dedupe (TB) 8.0 max deduped size (TB) 8.0 Deduped data size (TB) 8.0

Add the ifconfig and vfiler commands to the hosting filer‟s /etc/rc (ie: /vol/vol0/etc/rc) to make them persistent
Note: Data ONTAP 7.1+ does not require steps 7-8 as vfiler create asks all the necessary questions.
10.2 MultiStore (vfiler) Administration Step Command/Action Description
1
FAS1> vfiler status [-a|-r] vfiler1 running
Check vfiler status [-a shows Allowed protocols]
2
FAS1> ipspace list

11.6 sample /etc/snapmirror.conf
The snapmirror.conf file uses the same syntax as the Unix crontab file. Because SnapMirror is a pull technology, you should edit the snapmirror.conf file on the destination. The following examples show different ways to set up snapmirror schedules.
The following entry indicates that fridge's qtree home, in volume vol2 will mirror qtree home, in volume vol1 from toaster. Transfer speed is set at a maximum rate of 2,000 kilobytes per second. The four asterisks mean transfers to the mirror are initiated every minute, if possible. (If a previous transfer is in progress at the minute edge, it will continue; a new transfer will be initiated at the first minute edge after the transfer has completed.) toaster:/vol/vol1/home fridge:/vol/vol2/home kbs=2000 * * * * The following entry, between the db volumes on fridge-gig dev and icebox, is kicked off every five minutes, starting at 0. (Note fridge-gig is just a network interface name. In this case, a gigabit ethernet link on fridge.) fridge-gig:db icebox:db - 0-55/5 * * * The following entry makes transfers every half hour, with the first at 8:15 a.m., and the last at 6:45 p.m. The asterisks mean that the data replication schedule is not affected by the day of month or week; in other words, this series of transfers are initiated every day. filer1:build filer2:backup - 15,45 8,9,10,11,12,13,14,15,16,17,18 * * Data ONTAP 7.3 introduced compression to SnapMirror which makes some significant changes to the config file. Each relationship now requires a „connection‟ definition line at the top of the file that defines the network path(s) to connect a source and destination together using the following syntax: connection_name=mode (source_IP, destination_IP) (source_IP, dest_IP) fas1_DR=multi(10.10.10.50,10.10.10.200) (192.168.1.52,192.168.1.202) fas1_DR:user_vol fas2:user_vol_dr compression=enable 15,45 *** In this example 10.10.10.50 is the 10Gb/E interface for FAS1 and .200 is the 10Gb/E interface on FAS2. In the second parentheses, 192.168.1.52 is a 1Gb VIF on FAS1 and .202 is the 1Gb VIF on FAS2. The „multi‟ says to use the 10Gb/E interfaces first and if they fail to use the 1Gb VIF connections. The next line is the standard schedule but with the compression option included. Note: Currently, SnapMirror compression will NOT work if you use hostnames instead of IP addresses (you must add the systems to /etc/hosts – which defeats the purpose of DNS). Old snapmirror.conf files may need to be changed to use IP addresses in order to work with compression. # minute hour dayofmonth dayofweek(0-Sunday to 6-Sat) ####define snapmirror compression relationships na01-na02=multi (192.168.1.107,192.168.1.112) fas1=multi(10.10.10.50,10.10.10.200) (192.168.1.52,192.168.1.202) ###end ##Start snapmirror fridge-gig:db icebox:db - 0-55/5 * * * filer1:build filer2:backup - 15,45 8,9,10,11,12,13,14,15,16 * * fas1_DR:user_vol fas2:user_vol_dr compression=enable 15,45 * * * na01-na02:vmware013 na02:sm_vmware013 compression=enable - - - -
