Dell EMC Virtual Appliance Manager 9.2.1 Installation Guide or unisphere vapp

 

Launching the vApp Manager

About this task

To launch the vApp Manager:

Steps

1. Type one of the following URLs in a browser:
   • https://appliance_IP:unisphere_port_number
   • https://appliance_host_name:unisphere_port_number
   The default Unisphere port number is 5480.

   If the host IP address is an IPv6 address, surround the IP address with square brackets, for example:

   https://[2001:db8:ffff:ffff:ffff:ffff:ffff:ffff]:5480

   If the host IP address is an IPv4 address, type the IP address as normal, for example:

   https://198.51.100.255:5480

   For either of the URLs above, the browser is redirected, as shown in the following table.

   ORIGINAL URL	REDIRECTED URL
   https://appliance_IP:unisphere_port_ number	https://appliance_IP:unisphere_port_ number/vappmgr/#/login
   https://appliance_host_name:unisphere_port_ number	https://appliance_IP:unisphere_port_ number/vappmgr/#/login

2. On the log in panel, type seconfig for both the User and Password, and then click Login.
   The vApp Manager opens. For more information, see the vApp Manager online help.

Additional Information

SSH will need to be enabled after each reboot of the vApp. This is as designed.

The default credentials for SSH / CLI is cseadmin / cseadmin.

Brocade config backup and supportsave commands

 Before doing any kind of changes to a Brocade FC switch it’s a good idea to backup its config first. We backup Brocade switches using the configupload command.

Prerequisites – The switches need an FTP server to backup to.  You will need to know the IP address of the FTP server and a user account with access to proceed.

1 Establish a putty session to the switch and login as normal

2 Enter the command

configupload

3 At the protocol selection prompt choose the protocol appropriate for you FTP server. Press enter to select the default FTP

Protocol (scp, ftp, sftp, local) [ftp]

4 At the IP Address prompt enter the IP address of the FTP server

Server Name or IP Address [host]: 10.10.10.5

5 User Name, enter a user with access

User Name [user]

6 Path/filename, press enter to accept the home directory or enter path

Path/Filename [<home dir>/config.txt]:

7 Section, press enter to select all components or enter the element to backup

Section (all|chassis|switch [all]):

8 Go to your FTP server and you should see a file called config.txt.  Rename this to something logical like the switch name and date

Below is an example of all the steps completed

FCSWITCH01:admin> configupload
Protocol (scp, ftp, sftp, local) [ftp]:
Server Name or IP Address [host]: 10.10.10.5
User Name [user]: anonymous
Path/Filename [<home dir>/config.txt]:
Section (all|chassis|switch [all]):

Use the “supportsave” CLI command. Be aware: This needs an FTP server to be configured and running on a management workstation reachable by the switch!
Example:
 
Supportsave
 
This command will collect RASLOG, TRACE, supportShow, core file, FFDC data and other support information and then transfer them to a FTP/SCP server or a USB device. This operation can take several minutes.
..
..
OK to proceed? (yes, y, no, n): [no] y
Host IP or Host Name: xxx.xxx.xxx.xxx
User Name: YYYY
Password:
Protocol (ftp or scp):
 
Your FTP server will receive multiple files. Please compress them and give the resulting archive file a meaningful name. For example:
TicketNumber_SwitchName_Date_Description.zip

Brocade switch reboot process

 

Description

Use this command to perform a "cold reboot" (power off/restart) of the control processor. This operation may be disruptive, and the command prompts for confirmation before executing. When you reboot a switch connected to a fabric, all traffic to and from that switch stops. All Fibre Channel ports on that switch including E_Ports become inactive until the switch comes back online.

The behavior of this command depends on the platform:

When issued on a standalone (single-processor) switch, this command performs a cold reboot of the switch.
When issued on an enterprise-class platform (Brocade X6-4 Director or Brocade X6-8 Director) with two CPs (active and standby), the following rules apply:
When the Standby CP reboots, it goes down and there is no failover because there is no traffic on that switch. When the Standby CP comes up again, it is temporarily no longer in sync with the Active CP.
When the Active CP reboots, it fails over to the Standby CP. The Standby CP becomes the new Active CP and traffic is disrupted.
When HA is in sync, and 
reboot -f
 is issued on the Active CP of a director, the Standby CP takes over as the active CP without traffic disruption. If HA is not in sync, and 
reboot -f
 is issued on the Active CP, the Standby CP takes over as the Active CP and traffic is disrupted.
When HA is disabled and 
reboot
 or 
reboot -f
 is issued on the Active CP, both the Active and Standby CPs reboot with the original mastership retained. The original Active CP remains the Active CP after the reboot, and the original Standby CP remains the Standby CP. After the reboot, HA is enabled.
When HA is disabled and 
reboot
 or 
reboot -f
 is issued on the Standby CP, the Standby CP reboots without prompting. It boots up with the default switch only, even if the Active CP has multiple logical switches configured. After the Standby CP boots up, HA is still disabled.

Notes

This command is subject to Virtual Fabric restrictions that may be in place. See "Using Fabric OS Commands" and "Command Availability" for details.

Operands

-f

Causes the CP to fail over to the Standby CP without affecting any of the Fibre Channel Ports. Note that the recommended way to force a failover without affecting any Fibre Channel ports is to issue the 

haFailover

 command.

Examples

To reboot a standalone switch with a single CP:

switch:admin> 
reboot
				

Warning: This command would cause the switch to reboot

and result in traffic disruption.

Are you sure you want to reboot the switch [y/n]? 
y
				

Rebooting! Sun Feb 28 19:49:45 2010...

The system is going down for reboot NOW !!

To reboot a CP when HA is enabled:

switch:admin> 
reboot
				

Warning: This command is being run on a control processor (CP)

based system and will cause the active CP to reboot.

Are you sure you want to reboot the active CP [y/n]? 
y
				

Rebooting! Sun Feb 28 19:49:45 2010...

The system is going down for reboot NOW !!

To reboot a CP when 

haFailover

 is disabled:

switch:admin> 
reboot
				

 This command is being run on a control processor (CP) 

 based system. Because HA is disabled, it will cause both 

 active CP and the standby CP to reboot. After reboot, the 

 HA will be enabled.

 Do you want to continue [y/n]

 Rebooting!  Sun Feb 28 19:49:45 2010...

 The system is going down for reboot NOW !!
