dell md3000 storage array
Posted on 2014-12-16
I have a Dell MD3000 (15TB raw) in a RAID6, single datastore, and have added an MD1000 (8 TB raw). Using the Dell MDSM tool, I am adding the new 1TB disks in the expansion module to the RAID - one at a time. Not actually sure how long this took for the first disk. May have been a week. The operation to add the second drive has been in progress for 3 days.
Is anyone aware of settings I should tweak during this process, like disable media scan. Should I do this while my VM hosts are in maintenance mode? Is it likely to be impacted by path redundancy issues or a firmware mismatch? After adding the MD1000, I have an "Expansion Enclosure - Loss of Path Redundancy" error that I have been unable to resolve.
