Thanks to all for the many replies. Turns out the disks are not mirrored
that we need to upgrade (Some decision taken some time back before I came on
the scene.) - although there are other disks which are. Second thing I
forgot to mention was that the disks are part of an ase cluster service.
Thanks to Toby Shalless for mentioning this.
Out of all the options we have come down to only 2 that will work on our
setup.
1) Trash the lot and rebuild with the new disks - (Note: take backups first)
- This is the simplest but perhaps longest and does require downtime.
2) Manipulate the ADVFS domain with addvol/rmvol to enable the disks to be
upgraded - more complicated, does require a rebuild of the ase service, but
means the other cluster member can continue to run.
We have decided to go with option 2 (mainly to test the option for future
knowledge ;-)) with option 1 as a standbye.
People asked if the version the system was - 4.0F cluster V1.6
People asked if we had the needed licenses - we do.
People suggested breaking the mirror and rebuilding one side first,
vdump|vrestore the data, rebuild the second side and resync the mirror.
People suggested adding a third plex to the mirror and breaking out the old
one at a time.
Each of the above would work if we had space in the cabinet I am sure.
Unfortunately sheez a little bit full.
Thanks again to all who offered their support. Will give another additional
summary after the outcome.
