I had a pair of 4 TB disks go south this week. These are in a Dell R415 with 6/i PERC. They were in a RAID 1. One completely failed and the other was showing predicted failure.
I ordered a pair of drives, put one in place of the failed one, but since they were not exactly the same, the rebuild failed. So I popped all the drives, cleared the config, configured two RAID 0's with the "failing" drive in one and the new one in the other. I copied all the VMs to the new datastore and got all VMs running.
I then took the system down, popped all the drives, cleared the config, put the other new drive in and rebuilt the config as RAID 1.
I will add here, there is a second RAID 1 of two 200 GB drives, which is the boot volume.
Upon booting the system and connecting to vSphere client, I found that the 4 TB datastore was missing:
Rescan All... did not show it. I tried Add Storage > Disk/LUN and see this:
I highlight "Local DELL Disk (naa...." and click next, then see this:
I have tried a PERC reconfig, no change. Logging into EXS using Putty and looking at devices shows:
So, it appears my volume is there, but I cannot get it back as a datastore.
Any ideas?
Thank you!
