c7000 Fibre Channel Pass-Thru module firmware update?

Bill had a firmware update question:




Is the Fibre Channel Pass-Thru module firmware update disruptive? I didn’t see anyplace where this is addressed.




Monty replied:





As indicated in the Customer Advisory, you will lose connections on a pass-thru firmware update.  If the servers are configured for dual-path to storage, following the procedure below will take advantage of that dual-path to not disrupt the server.


Here is the info:


Pass-Thru Module Firmware Upgrade


Note: In c-Class enclosures configured with multiple 4 Gb Fibre Channel Pass-Thru Modules that provide a dual path to the storage system, upgrade the firmware version for each Fibre Channel Pass-Thru module one module at a time.


The procedure below includes the step-by-step instructions necessary to successfully upgrade the firmware on multiple Pass-Thru Modules. Upgrade the module in bay location 3A prior to initiating a firmware upgrade in bay location 4A. This will allow the dual-path fail over feature to access the storage system during the upgrade process.


However, in c-Class enclosures configured with a single Pass-Thru Module, the storage system cannot be accessed during the firmware upgrade process. Allow time for the normal firmware upgrade process to complete before attempting to access the storage system.





Any other comments or suggestions for Bill?
