How to identify the crashed disk (DSM->RDM->HP Gen8 Raid0->physical drive)


Recommended Posts

Hi guys,


I am caught with a degraded disk array in DSM.


1 of 4 3TB WD Red had bad sector errors and DSM degraded the disk array. In DSM Drive Nr. 5 is shown as dead.

I got a replacement disk but now I am unable to identify the physical disk, which is dead.


Because of the buildin Raid Controller B120i I declared every single disk as seperate Raid0. Within the ESX, I published the drives as RDM Mapping into the DSM.


Now I need to follow the chain DSM -> RDM Link -> Raid0 -> Driveslot to get the proper disk replaced, but have no clue how to do?
