Background:
We have PowerVault MD3460 Array - all Disks presented a JBOD LUNs. Ie., each Disk is a single VirtualDisk, which in-turn mapped to a single LUN and presented as LUN to a host. Hosts connected via SAS bus., and hosts-to-array SAS WWNs are already masked.
In essence, all the drives are nothing but JBOD Luns to host(s). No RAID, no complex configuration. One Disk mapped as --> One VirtualDisk, in-turn presented as LUN to --> One Host/HBA
Issue:
Every now and then - SATA drives fail, hence, a host would lose corresponding JBOD LUN presented.
Question:
Is there a simple way to REPLACE a failed disk ? We would like to Automate and Simplify this task in our DataCenter environment ? GUI is OK, but not best suited for our environment, we are comfortable with SMCLI tool.
Ie., after replacing the failed-disk with a NEW disk, is there a simple command or process to bring back the configuration (ie., Disk to VD, VD to LUN mapping etc) ?
Thanks in Advance!
** Note: We know we've lost the data on that old/failed disk - in this case., host(s) are handling the Data-mirroring., so we are OK with loss of copy data on that failed disk. No SPARES on the arrays. All we are trying to do is - preserve the original Disk/VD/LUN-mapping configuration AFTER the new disk come into place of the old/failed disk.
