[gpfsug-discuss] GNR/GSS/ESS pdisk location

[Matthew Robinson]

Hi Valdis,

Normally the name will indicate the physical location of the disk.

So the name of the disk you have listed is  "e2d3s11" this is Enclosure 2
Disk shelf 3 Disk slot 11.  However, based on the location = "" this is the
reason for the failure of the tscommand failure. Normally a recovery group
rebuild fixes the issue from what I have seen in the past.
