Upgrade the Switch Firmware (CLI)

Language:

Note - Before upgrading or downgrading the switch firmware, read Firmware Update Guidelines.

Open an SSH session as user ilom-admin and connect to the management controller by specifying the controller's host name.
For example:
```
% ssh -l ilom-admin switch_name
ilom-admin@switch_name's password: password
->
```
where switch_name is the host name of the management controller. Initially, the password is ilom-admin.

(Optional) If the Subnet Manager is running on the management controller, disable the Subnet Manager.

-> start /SYS/Fabric_Mgmt
Are you sure you want to start /SYS/Fabric_Mgmt (y/n)? y

NOTE: start /SYS/Fabric_Mgmt will launch a restricted Linux shell.
      User can execute switch diagnosis, SM Configuration and IB 
      monitoring commands in the shell. To view the list of commands, 
      use "help" at rsh prompt. 

      Use exit command at rsh prompt to revert back to
      ILOM shell.

Begin the upgrade process.
```
-> load -source URI/pkgname
```
where:
- URI is the uniform resource indicator for the host where the switch firmware package is located. The FTP, TFTP, and HTTP protocols are supported when upgrading from firmware 2.1. If upgrading from firmware 2.2, SFTP and SCP are also supported.
- pkgname is the name of the firmware package in the transfer directory.
For example, using the HTTP protocol:
```
-> load -source http://123.45.67.89/tmp/sundcs_36p_repository_2.2.14_1.pkg
Downloading firmware image. This will take a few minutes.
```
The firmware is downloaded. The upgrade begins. If you did not disable the Subnet Manager, a warning is displayed. You are asked to commit to the upgrade.
```
NOTE: Firmware upgrade will upgrade the SUN DCS 36p firmware.
      ILOM will enter a special mode to load new firmware. No
      other tasks should be performed in ILOM until the firmware
      upgrade is complete.

WARNING: Subnet manager is running on the switch. Proceeding with
installation will stop it.
```

Answer y to the prompt to commit to the upgrade.

The upgrade begins.

Are you sure you want to load the specified file (y/n)? y
Setting up environment for firmware upgrade. This will take a few minutes.

Subnet manager has been temporarily disabled on this switch so that
firmware upgrade can go on. After the upgrade is done, please make
sure that the SM is running again, using commands sminfo and enablesm.

Starting SUN DCS 36p FW update

==========================
Performing operation: I4 A
==========================
I4 A: I4 is already at the given version.

=========================================
Performing operation: SUN DCS 36p firmware update
=========================================
SUN DCS 36p Kontron module fw upgrade from 2.2.9-3 to 2.2.14-1:
Please reboot the system to enable firmware update of Kontron module. The
download of the Kontron firmware image happens during reboot.

After system reboot, Kontron FW update progress can be monitored in browser
using URL [http://system] OR at OS command line prompt by using command
[telnet system 1234] where system is the hostname or IP address of SUN DCS
36P or GW.

Firmware update is complete.

Restart the switch to enable the new firmware.

-> reset /SP
Are you sure you want to reset /SP (y/n)? y
Performing reset on /SP
Broadcast message from root@switch_name
        (unknown) at 9:36 ...
The system is going down for reboot NOW!
-> Connection to switch_name closed by remote host.
Connection to switch_name closed.
-bash-3.2$

Caution - Do not power cycle or reset the switch prior to completion of the reset process, as that will interrupt the firmware installation.

Note - The reset process takes about 4 to 5 minutes. However, it can take longer if management network or the server hosting the firmware has limited resources.

You can monitor the update progress through:

web browser – http://switch_name
CLI – telnet switch_name 1234

where switch_name is the host name or IP address of the management controller.

Note - The Oracle ILOM stack requires at least 2 minutes to become operational after a reboot.

The next time you log in to the switch, this message is displayed:

FW upgrade completed successfully on Wed Aug 14 16:06:14 CET 2019.
Please run the "fwverify" CLI command to verify the new image.
This message will be cleared on next reboot.

Access the restricted Linux shell, and verify the firmware version.

% ssh -l ilom-admin switch_name
ilom-admin@switch_name's password: password
-> start /SYS/Fabric_Mgmt
Are you sure you want to start /SYS/Fabric_Mgmt (y/n)? y
  
NOTE: start /SYS/Fabric_Mgmt will launch a restricted Linux shell.
      User can execute switch diagnosis, SM Configuration and IB 
      monitoring commands in the shell. To view the list of commands, 
      use "help" at rsh prompt. 

      Use exit command at rsh prompt to revert back to 
      ILOM shell.

In the first line of the output for the version command is SUN DCS 36p version x.y.z-w, where x.y.z-w is the version of the firmware upgraded (or downgraded). For example, 2.2.14-1.

If you disabled the Subnet Manager in Step 2, enable it now.
