I've just updated the firmware on our SAN disk. It completed successfully. We have 10 volumes and 9 are running as expected. 1 is in an inactive state.
The SAN is an HP P2000. The volume is 2.6TB, there are 3 virtual machines on the volume. I'm not sure if its relevant but the disk is a VMFS3 that is showing as 2TB (0.6TB lower than the volume, so i guess there's a file size limit).
All help is welcome.
