You can specify which disk to upgrade. Try

disk_fw_update <diskname>

This works while the system is running.

I have a 840 cluster. Whenever I add new disks, the cluster starts throwing 'doenrev disk firmware' error messages. NetApps suggests doing a disk_fw_update on the disk and strictly says "NO need to Halt a filer'. Reality is totally different. The command specifically asks you wether the cluster partner is on Halt-OK prompt or not?

The workaround I am doing, intitiate a takeover and do the disk_fw_update. However, this still needs to do a takeover/giveback and 2 minutes of downtime...Adding/replacing bad disks is a regular activity...

Any suggestions..?
