Shelf reported as unknown from sysconfig -a output
Applies to
- FAS systems
- ONTAP 9
- DS2246 disk shelves
Issue
- Disk shelf status is reported as unknown through one adapter on both nodes in the HA pair:
::> system node run -node * sysconfig -a
Node-01
slot 0: SAS Host Adapter 0d (PMC-Sierra PM8001 rev. C, SAS, <UP>)
Firmware rev: 01.12.09.00
Shelf 27: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf 28: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf ?: unknown NUTAPP:DS224IOM6
Node-02
slot 4: SAS Host Adapter 4c (PMC-Sierra PM8001 rev. C, SAS, <UP>)
MFG Part Number: USI 6086-000010-07 rev. MP V4.10
Shelf 27: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf 28: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf ?: unknown NUTAPP:DS224IOM6
- The same shelf is reported normally from the other adapter:
::> system node run -node <node> sysconfig -a
slot 4: SAS Host Adapter 4a (PMC-Sierra PM8001 rev. C, SAS, <UP>)
MFG Part Number: USI 6086-000010-07 rev. MP V4.10
Shelf 27: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf 28: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
Shelf 29: DS2246 Firmware rev. IOM6 A: 0191 IOM6 B: 0191
- Both nodes are connected to a common IOM through the adapter that reports the shelf as unknown:
::> system node run -node * -command sasadmin expander_map
Node-01

- The disks are detected normally from both adapters.
- The following event may be reported in the event logs:
[Node-01: dsa_disc: ses.shelf.unsupportAllowErr:alert]: Unsupported disk shelf found on channel 0d.
- Reseat of the affected IOM does not resolve the issue.
