HP Storageworks San Switch firmware downgrade/upgrade

Did a firmware downgrade and upgrade for HP storagework 4/32 san switch a couple of days ago.

The things to take note

Firmware has to be downgrade step by step base on the FABOS version. (Example Upgrading from 5.1 requires the following upgrade path: 5.2.x - 5.3.x - 6.1.x - 6.2.x. )

Cannot be upgraded in one shot (example 5.3.1 to 6.4.1)

Firmware upgrade will affect performance of storage boxes also.
important: SAS firmware has to be upgraded as well.

Tools needed
- Inorder to console to the switch, you must have a brocade serial cable (with DTE support), else all else will fail.
- ftp server
- any cat5 cable
- IE with latest java

The commands needed ( command varies from brocade FOS series)




Example

switch:admin>

firmwaredownload

This command will upgrade both CPs in the switch. If you

what to upgrade a single CP only, please use -s option.

You can run firmwareDownloadStatus to get the status

of this command.

This command will cause the active CP to reset and will

require that existing telnet, secure telnet, or SSH sessions

be restarted.
