I have a question about the timing on upgrading disk firmware. With the recent DOT's when you do a DOT upgrade, after you reboot and a disk firmware upgrade is needed, DOT warns you at boot time, at which point you can do a disk_fw_update. This is when I've upgraded disk firmware. However, the NOW documentation isn't clear if this is the appropriate time to upgrade the disk firmare.
So, my question is, when is the best time to upgrade the disk firmware:
1) After you've run install_netapp, but before you've run 'download'. 2) After you've run download. 3) After you've rebooted on the new DOT version.
Also, are there any cluster considerations associated with the choice of timing? I noticed when upgrading a cluster this weekend that I received downrev messages from the NetApps until both partners had the same disk firmware.
