Upgrade the Switch Firmware (Web)

Note - If you are going to downgrade the firmware to a version earlier than 2.1, you must disable secret M_Keys. Refer to Switch Administration, disabling secret M_Key functionality.

Note - If you are going to downgrade the firmware to a version earlier than 2.0, you must remove user partitions and depopulate the Subnet Manager nodes list. Refer to Switch Administration, removing partitions for firmware downgrade.

Acquire the firmware package.
See Acquire the Switch Firmware Package (CLI).
Consider your next step.
- If you are upgrading from firmware version 2.0 or newer, go to Step 9.
- If you are upgrading from a firmware version earlier than 2.0, go to Step 3.
Open an SSH session as user root and connect to the management controller by specifying the controller's host name.
```
% ssh -l root switch_name
root@switch_name's password: password
#
```
where switch_name is the host name of the management controller. Initially, the password is changeme.

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

# disablesm

#

Verify that there is at least 80 MB available in the / filesystem.
```
# df -h /
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda2             471M  276M  172M  62% /
#
```
In this example, there are 172 MB available. If not enough space is available, you must delete or move files from the / filesystem.
Verify that there is at least 120 MB available in the /tmp directory.
```
# df -h /tmp
Filesystem            Size  Used Avail Use% Mounted on
tmpfs                 250M  240K 249M 1% /tmp
#
```
In this example, there are 249 MB available. If not enough space is available, you must delete files from the /tmp directory.
If you will perform a local file upload, perform these steps.
Otherwise, go to Step 8.
1. Verify that there is at least 120 MB available in the /dev/shm directory.
```
# df -h /dev/shm
Filesystem            Size  Used Avail Use% Mounted on
tmpfs                 250M   16K  250M   1% /dev/shm
#
```
  In this example, there are 250 MB available. If not enough space is available, you must delete or move files from the /dev/shm directory.
2. Verify that there is at least 240 MB free memory available.
```
# free -m
                 total       used       free     shared    buffers     cached
Mem:           498        104        393          0         12         47
-/+ buffers/cache:         45        453
Swap:            0          0          0
#
```
  In the -/+ buffers/cache: row of the free column, there should be at least 240 MB free memory. In this example, there are 453 MB available. If not enough memory is available, you must exit nonessential applications that are running.
3. Go to Step 9.
Verify that there is at least 120 MB free memory available.
```
# free -m
                 total       used       free     shared    buffers     cached
Mem:           498        104        393          0         12         47
-/+ buffers/cache:         45        453
Swap:            0          0          0
#
```
In the -/+ buffers/cache: row of the free column, there should be at least 120 MB free memory. In this example, there are 453 MB available. If not enough memory is available, you must exit non-essential applications that are running.
Access the Oracle ILOM web interface.
See Access Oracle ILOM From the Web Interface.
Click the Maintenance tab.
Click the Firmware Upgrade subtab.
The Firmware Upgrade pane is displayed.
Click Enter Upgrade Mode.
A dialog box opens and asks you to confirm.
Click OK.
The Firmware Upgrade window changes to Upgrade mode and now accepts either a local file path and file name, or a URL and file name of the switch firmware package.
Consider your next step:
- # If you are performing a local file upload, click Browse and locate the file.
- # If the switch firmware package is located remotely, click Specify URL and type the fully qualified URL for the package.
Note - Clicking Specify URL also changes the button to Local File Upload. Clicking Local File Upload changes the button back to Specify URL.

Note - For the specified URL, only the FTP or HTTP protocols are supported.
Click Upload.
Oracle ILOM transfers the switch firmware package to the management controller. Oracle ILOM verifies the package integrity and displays the current versions of the firmware and versions in the package.
Click Start Upgrade.
A dialog box opens and asks you to confirm.
Click OK.
The upgrade begins and the status of the upgrade is reported.
When the upgrade process ends, a log and summary report are displayed.
Click OK.
A final status is displayed, the upgrade either:
- Succeeded
- Partially succeeded
- Failed
Reboot the switch to enable the new firmware.
Refer to Switch Administration, restarting the entire switch.

Note - The restart process takes between 4 to 5 minutes to complete. The Oracle ILOM stack requires at least 2 minutes to become operational after a reboot.

If the Subnet Manager was disabled in Step 4, log in to Oracle ILOM, access the restricted Linux shell, and enable the Subnet Manager.

% ssh -l ilom-admin switch_name
ilom-admin@switch_name's password: password
-> show /SYS/Fabric_Mgmt
NOTE: show on 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.
