Answer

  • The '1.x.x' format and the '0b.x.x' format are different because they are identifiers for disks recognized under the cluster shell and node shell, respectively.

Cluster shell example:
::> storage disk show
                     Usable           Container
Disk                   Size Shelf Bay Type        Position   Aggregate Owner
---------------- ---------- ----- --- ----------- ---------- --------- --------
1.1.1                  10GB     1   1 spare       present    -         node1
1.1.4               78.59GB     1   4 spare       present    -         node1
1.1.12                 10GB     1  12 spare       present    -         node1

Node shell example:
ontap913-01> disk show
  DISK       OWNER               POOL   SERIAL NUMBER         HOME                    DR HOME
------------ -------------      -----  -------------         -------------           -------------
0b.00.18P2        ontap913-01   Pool0  079XXX              ontap913-01
0b.00.18P1        ontap913-01   Pool0  079XXX              ontap913-01
 
  • Therefore, when performing a disk unpartition, please specify as follows:
    • For command execution under the cluster shell, use the '1.x.x' format.
    • For command execution under the node shell, use the '0b.x.x' format.
