SAS shelves

Issue

  • The device ID disk in the SAS shelves is expected to be similar to 2d.10.1 following the standard convention: device_id = Adapter.ShelfID.BayID
  • When reviewing the output of sysconfig -a or sysconfig -r, a long alpha numeric number is in use for the shelf ID instead of the expected number from 0-98.

Example:

Cluster::> system node run -node <node name> -command sysconfig -a

002115F8.21: NETAPP   X343_STBTE1T8A10 NA02 1713.5GB 520B/sect
002115F8.22: NETAPP   X343_STBTE1T8A10 NA02 1713.5GB 520B/sect
002115F8.23: NETAPP   X343_STBTE1T8A10 NA02 1713.5GB 520B/sect

Cluster::> system node run -node <node name> -command sysconfig -r

0c.002115F8.21    0c    10  21  SA:B   0   SAS 10000 1713523/3509295616 1716957/3516328368
0c.002115F8.22    0c    10  22  SA:B   0   SAS 10000 1713523/3509295616 1716957/3516328368
0c.002115F8.23    0c    10  23  SA:B   0   SAS 10000 1713523/3509295616 1716957/3516328368

  • Checking STORAGE-SHELF we may also see that there is more than one shelf reporting the same shelf ID:

           Shelf name:    name.shelf1
           Shelf id:      0

           Shelf name:    name.shelf2
           Shelf id:      0

  • Messages similar to the below may also be observed in EMS-LOG-FILE:

node1 ALERT ses.inconsistent.config: Inconsistent configuration detected for shelf connected to adapter 0b, 0c.
node1 ALERT ses.multipath.ReqError: SAS disk shelf detected without a multipath configuration.
node1 ALERT ses.inconsistent.config: Inconsistent configuration detected for shelf connected to adapter 0b, 0c.
node1 ALERT ses.multipath.ReqError: SAS disk shelf detected without a multipath configuration.
node1 ALERT ses.inconsistent.config: Inconsistent configuration detected for shelf connected to adapter 0b, 0c.
