NetApp 7-mode Commandline

NetApp Command line Cheat sheet

This is a quick and dirty NetApp commandline cheatsheet on most of the common commands used, this is not extensive so check out the man pages and NetApp documentation. I will be updating this document as I become more familiar with the NetApp application.

Server

Startup and Shutdown
Boot Menu		1) Normal Boot. 2) Boot without /etc/rc. 3) Change password. 4) Clean configuration and initialize all disks. 5) Maintenance mode boot. 6) Update flash from backup config. 7) Install new software first. 8) Reboot node. Selection (1-8)? Normal Boot - continue with the normal boot operation Boot without /etc/rc - boot with only default options and disable some services Change Password - change the storage systems password Clean configuration and initialize all disks - cleans all disks and reset the filer to factory default settings Maintenance mode boot - file system operations are disabled, limited set of commands Update flash from backup config - restore the configuration information if corrupted on the boot device Install new software first - use this if the filer does not include support for the storage array Reboot node - restart the filer
startup modes		boot_ontap - boots the current Data ONTAP software release stored on the boot device boot primary - boots the Data ONTAP release stored on the boot device as the primary kernel boot_backup - boots the backup Data ONTAP release from the boot device boot_diags - boots a Data ONTAP diagnostic kernel Note: there are other options but NetApp will provide these as when necessary
shutdown		halt [-t <mins>] [-f] -t = shutdown after minutes specified -f = used with HA clustering, means that the partner filer does not take over
restart		reboot [-t <mins>] [-s] [-r] [-f] -t = reboot in specified minutes -s = clean reboot but also power cycle the filer (like pushing the off button) -r = bypasses the shutdown (not clean) and power cycles the filer -f = used with HA clustering, means that the partner filer does not take over
System Privilege and System shell
Privilege	priv set [-q] [admin | advanced] Note: by default you are in administrative mode -q = quiet suppresses warning messages

Disks

Disk Information
Disk name	This is the physical disk itself, normally the disk will reside in a disk enclosure, the disk will have a pathname like 2a.17 depending on the type of disk enclosure 2a = SCSI adapter 17 = disk SCSI ID Any disks that are classed as spare will be used in any group to replace failed disks. They can also be assigned to any aggregate. Disks are assigned to a specific pool.
Disk Types
Data	holds data stored within the RAID group
Spare	Does not hold usable data but is available to be added to a RAID group in an aggregate, also known as a hot spare
Parity	Store data reconstruction information within the RAID group
dParity	Stores double-parity information within the RAID group, if RAID-DP is enabled

General Volume Operations (Traditional and FlexVol)
Displaying		vol status vol status -v (verbose) vol status -l (display language)
Remove (destroying)		vol offline <vol_name> vol destroy <vol_name>
Rename		vol rename <old_name> <new_name>
online		vol online <vol_name>
offline		vol offline <vol_name>
restrict		vol restrict <vol_name>
decompress		vol decompress status vol decompress start <vol_name> vol decompress stop <vol_name>
Mirroring		vol mirror volname [-n][-v victim_volname][-f][-d <disk_list>] Note: Mirrors the currently-unmirrored traditional volume volname, either with the specified set of disks or with the contents of another unmirrored traditional volume victim_volname, which will be destroyed in the process. The vol mirror command fails if either the chosen volname or victim_volname are flexible volumes. Flexible volumes require that any operations having directly to do with their containing aggregates be handled via the new aggr command suite.
Change language		vol lang <vol_name> <language>
Change maximum number of files		## Display maximum number of files maxfiles <vol_name> ## Change maximum number of files maxfiles <vol_name> <max_num_files>
Change root volume		vol options <vol_name> root
Media Scrub		vol media_scrub status [volname|plexname|groupname -s disk-name][-v] Note: Prints the media scrubbing status of the named aggregate, volume, plex, or group. If no name is given, then status is printed for all RAID groups currently running a media scrub. The status includes a percent-complete and whether it is suspended. Look at the following system options: raid.media_scrub.enable on raid.media_scrub.rate 600 raid.media_scrub.spares.enable on
FlexVol Volume Operations (only)
Adding (creating)		## Syntax vol create vol_name [-l language_code] [-s {volume|file|none}] <aggr_name> size{k|m|g|t} ## Create a 200MB volume using the english character set vol create newvol -l en aggr1 200M ## Create 50GB flexvol volume vol create vol1 aggr0 50g
additional disks		## add an additional disk to aggregate flexvol1, use "aggr status" to get group name aggr status flexvol1 -r aggr add flexvol1 -g rg0 -d v5.25
Resizing		vol size <vol_name> [+|-] n{k|m|g|t} ## Increase flexvol1 volume by 100MB vol size flexvol1 + 100m
Automatically resizing		vol autosize vol_name [-m size {k|m|g|t}] [-I size {k|m|g|t}] on ## automatically grow by 10MB increaments to max of 500MB vol autosize flexvol1 -m 500m -I 10m on
Determine free space and Inodes		df -Ah df -I
Determine size		vol size <vol_name>
automatic free space preservation		vol options <vol_name> try_first [volume_grow|snap_delete] Note: If you specify volume_grow, Data ONTAP attempts to increase the volume's size before deleting any Snapshot copies. Data ONTAP increases the volume size based on specifications you provided using the vol autosize command. If you specify snap_delete, Data ONTAP attempts to create more free space by deleting Snapshot copies, before increasing the size of the volume. Data ONTAP deletes Snapshot copies based on the specifications you provided using the snap autodelete command.
display a FlexVol volume's containing aggregate		vol container <vol_name>
Cloning		vol clone create clone_vol [-s none|file|volume] -b parent_vol [parent_snap] vol clone split start vol clone split stop vol clone split estimate vol clone split status Note: The vol clone create command creates a flexible volume named clone_vol on the local filer that is a clone of a "backing" flexible volume named par_ent_vol. A clone is a volume that is a writable snapshot of another volume. Initially, the clone and its parent share the same storage; more storage space is consumed only as one volume or the other changes.
Copying		vol copy start [-S|-s snapshot] <vol_source> <vol_destination> vol copy status vol copy abort <operation number> vol copy throttle <operation_number> <throttle value 10-1> ## Example - Copies the nightly snapshot named nightly.1 on volume vol0 on the local filer to the volume vol0 on remote ## filer named toaster1. vol copy start -s nightly.1 vol0 toaster1:vol0 Note: Copies all data, including snapshots, from one volume to another. If the -S flag is used, the command copies all snapshots in the source volume to the destination volume. To specify a particular snapshot to copy, use the -s flag followed by the name of the snapshot. If neither the -S nor -s flag is used in the command, the filer automatically creates a distinctively-named snapshot at the time the vol copy start command is executed and copies only that snapshot to the destination volume. The source and destination volumes must either both be traditional volumes or both be flexible volumes. The vol copy command will abort if an attempt is made to copy between different volume types. The source and destination volumes can be on the same filer or on different filers. If the source or destination volume is on a filer other than the one on which the vol copy start command was entered, specify the volume name in the filer_name:volume_name format.
Traditional Volume Operations (only)
adding (creating)		vol|aggr create vol_name -v [-l language_code] [-f] [-m] [-n] [-v] [-t {raid4|raid_dp}] [-r raidsize] [-T disk-type] -R rpm] [-L] disk-list ## create traditional volume using aggr command aggr create tradvol1 -l en -t raid4 -d v5.26 v5.27 ## create traditional volume using vol command vol create tradvol1 -l en -t raid4 -d v5.26 v5.27 ## Create traditional volume using 20 disks, each RAID group can have 10 disks vol create vol1 -r 10 20
additional disks		vol add volname[-f][-n][-g <raidgroup>]{ ndisks[@size]|-d <disk_list> } ## add another disk to the already existing traditional volume vol add tradvol1 -d v5.28
splitting		aggr split <volname/plexname> <new_volname>
Scrubing (parity)		## The more new "aggr scrub " command is preferred vol scrub status [volname|plexname|groupname][-v] vol scrub start [volname|plexname|groupname][-v] vol scrub stop [volname|plexname|groupname][-v] vol scrub suspend [volname|plexname|groupname][-v] vol scrub resume [volname|plexname|groupname][-v] Note: Print the status of parity scrubbing on the named traditional volume, plex or RAID group. If no name is provided, the status is given on all RAID groups currently undergoing parity scrubbing. The status includes a percent-complete as well as the scrub’s suspended status (if any).
Verify (mirroring)		## The more new "aggr verify" command is preferred ## verify status vol verify status ## start a verify operation vol verify start [ aggrname ] ## stop a verify operation vol verify stop [ aggrname ] ## suspend a verify operation vol verify suspend [ aggrname ] ## resume a verify operation vol verify resume [ aggrname ] Note: Starts RAID mirror verification on the named online mirrored aggregate. If no name is given, then RAID mirror verification is started on all online mirrored aggregates. Verification compares the data in both plexes of a mirrored aggregate. In the default case, all blocks that differ are logged, but no changes are made.

FlexCache Consistency
Delegations	You can think of a delegation as a contract between the origin system and the caching volume; as long as the caching volume has the delegation, the file has not changed. Delegations are used only in certain situations. When data from a file is retrieved from the origin volume, the origin system can give a delegation for that file to the caching volume. Before that file is modified on the origin volume, whether due to a request from another caching volume or due to direct client access, the origin system revokes the delegation for that file from all caching volumes that have that delegation.
Attribute cache timeouts	When data is retrieved from the origin volume, the file that contains that data is considered valid in the FlexCache volume as long as a delegation exists for that file. If no delegation exists, the file is considered valid for a certain length of time, specified by the attribute cache timeout. If a client requests data from a file for which there are no delegations, and the attribute cache timeout has been exceeded, the FlexCache volume compares the file attributes of the cached file with the attributes of the file on the origin system.
write operation proxy	If a client modifies a file that is cached, that operation is passed back, or proxied through, to the origin system, and the file is ejected from the cache. When the write is proxied, the attributes of the file on the origin volume are changed. This means that when another client requests data from that file, any other FlexCache volume that has that data cached will re-request the data after the attribute cache timeout is reached.
FlexCache Status Values
access denied	The origin system is not allowing FlexCache access. Check the setting of the flexcache.access option on the origin system.
connecting	The caching system is trying to connect to the origin system.
lang mismatch	The language setting of the origin volume was changed since the FlexCache volume was created.
rem vol changed	The origin volume was deleted and re-created with the same name. Re-create the FlexCache volume to reenable the FlexCache relationship.
rem vol unavail	The origin volume is offline or has been deleted.
remote nvram err	The origin system is experiencing problems with its NVRAM.
unsup remote vol	The origin system is running a version of Data ONTAP that either does not support FlexCache volumes or is not compatible with the version running on the caching system.

Enabling ALUA		igroup set win_hosts_group1 alua yes Note: ALUA defines a standard set of SCSI commands for discovering and managing multiple paths to LUNs on Fibre Channel and iSCSI SANs. ALUA enables the initiator to query the target about path attributes, such as primary path and secondary path. It also enables the target to communicate events back to the initiator. As long as the host supports the ALUA standard, multipathing software can be developed to support any array. Proprietary SCSI commands are no longer required.

Export Options
actual=<path>	Specifies the actual file system path corresponding to the exported file system path.
anon=<uid>|<name>	Specifies the effective user ID (or name) of all anonymous or root NFS client users that access the file system path.
nosuid	Disables setuid and setgid executables and mknod commands on the file system path.
ro | ro=clientid	Specifies which NFS clients have read-only access to the file system path.
rw | rw=clientid	Specifies which NFS clients have read-write access to the file system path.
root=clientid	Specifies which NFS clients have root access to the file system path. If you specify the root= option, you must specify at least one NFS client identifier. To exclude NFS clients from the list, prepend the NFS client identifiers with a minus sign (-).
sec=sectype	Specifies the security types that an NFS client must support to access the file system path. To apply the security types to all types of access, specify the sec= option once. To apply the security types to specific types of access (anonymous, non-super user, read-only, read-write, or root), specify the sec= option at least twice, once before each access type to which it applies (anon, nosuid, ro, rw, or root, respectively). security types could be one of the following: none No security. Data ONTAP treats all of the NFS client's users as anonymous users. sys Standard UNIX (AUTH_SYS) authentication. Data ONTAP checks the NFS credentials of all of the NFS client's users, applying the file access permissions specified for those users in the NFS server's /etc/passwd file. This is the default security type. krb5 Kerberos(tm) Version 5 authentication. Data ONTAP uses data encryption standard (DES) key encryption to authenticate the NFS client's users. krb5i Kerberos(tm) Version 5 integrity. In addition to authenticating the NFS client's users, Data ONTAP uses message authentication codes (MACs) to verify the integrity of the NFS client's remote procedure requests and responses, thus preventing "man-in-the-middle" tampering. krb5p Kerberos(tm) Version 5 privacy. In addition to authenticating the NFS client's users and verifying data integrity, Data ONTAP encrypts NFS arguments and results to provide privacy.

Snapshotting and Cloning

Snapshot and Cloning commands
Display clones	snap list
create clone	# Create a LUN by entering the following command lun create -s 10g -t solaris /vol/tradvol1/lun1 # Create a Snapshot copy of the volume containing the LUN to be cloned by entering the following command snap create tradvol1 tradvol1_snapshot_08122010 # Create the LUN clone by entering the following command lun clone create /vol/tradvol1/clone_lun1 -b /vol/tradvol1/lun1 tradvol1_snapshot_08122010
destroy clone	# display the snapshot copies lun snap usage tradvol1 tradvol1_snapshot_08122010 # Delete all the LUNs in the active file system that are displayed by the lun snap usage command by entering the following command lun destroy /vol/tradvol1/clone_lun1 # Delete all the Snapshot copies that are displayed by the lun snap usage command in the order they appear snap delete tradvol1 tradvol1_snapshot_08122010
clone dependency	vol options <vol_name> <snapshot_clone_dependency> on vol options <vol_name> <snapshot_clone_dependency> off Note: Prior to Data ONTAP 7.3, the system automatically locked all backing Snapshot copies when Snapshot copies of LUN clones were taken. Starting with Data ONTAP 7.3, you can enable the system to only lock backing Snapshot copies for the active LUN clone. If you do this, when you delete the active LUN clone, you can delete the base Snapshot copy without having to first delete all of the more recent backing Snapshot copies. This behavior in not enabled by default; use the snapshot_clone_dependency volume option to enable it. If this option is set to off, you will still be required to delete all subsequent Snapshot copies before deleting the base Snapshot copy. If you enable this option, you are not required to rediscover the LUNs. If you perform a subsequent volume snap restore operation, the system restores whichever value was present at the time the Snapshot copy was taken.
Restoring snapshot	snap restore -s payroll_lun_backup.2 -t vol /vol/payroll_lun
splitting the clone	lun clone split start lun_path lun clone split status lun_path
stop clone splitting	lun clone split stop lun_path
delete snapshot copy	snap delete vol-name snapshot-name snap delete -a -f <vol-name>
disk space usage	lun snap usage tradvol1 mysnap
Use Volume copy to copy LUN's	vol copy start -S source:source_volume dest:dest_volume vol copy start -S /vol/vol0 filerB:/vol/vol1
The estimated rate of change of data between Snapshot copies in a volume	snap delta /vol/tradvol1 tradvol1_snapshot_08122010
The estimated amount of space freed if you delete the specified Snapshot copies	snap reclaimable /vol/tradvol1 tradvol1_snapshot_08122010

Useful CIFS options
change the security style		options wafl.default_security_style {ntfs | unix | mixed}
timeout		options cifs.idle_timeout time
Performance		options cifs.oplocks.enable on Note: Under some circumstances, if a process has an exclusive oplock on a file and a second process attempts to open the file, the first process must invalidate cached data and flush writes and locks. The client must then relinquish the oplock and access to the file. If there is a network failure during this flush, cached write data might be lost.

File Access using NFS

File Access using CIFS

File Access using FTP

Useful Options
Enable	options ftpd.enable on
Disable	options ftpd.enable off
File Locking	options ftpd.locking delete options ftpd.locking none Note: To prevent users from modifying files while the FTP server is transferring them, you can enable FTP file locking. Otherwise, you can disable FTP file locking. By default, FTP file locking is disabled.
