If the disk has keys which do not belong to a specific cluster, then the
vxfenadm command cannot look up the node name for the node ID and hence
prints the node name as unknown. For example:
Device Name: /dev/vx/rdmp/disk_7
Total Number Of Keys: 1
key[0]:
[Numeric Format]: 86,70,45,45,45,45,48,49
[Character Format]: VF----01
[Node Format]: Cluster ID: unknown Node ID: 1 Node Name: nebula
For disks with arbitrary format of keys, the vxfenadm command prints all
the fields as unknown. For example:
[Numeric Format]: 65,66,67,68,49,50,51,45
[Character Format]: ABCD123-
[Node Format]: Cluster ID: unknown Node ID: unknown
Node Name: unknown
Verifying that the nodes see the same disk
To confirm whether a disk (or LUN) supports SCSI-3 persistent reservations, two
nodes must simultaneously have access to the same disks. Because a shared disk
is likely to have a different name on each node, check the serial number to verify
the identity of the disk. Use the vxfenadm command with the -i option to verify
that the same serial number for the LUN is returned on all paths to the LUN.
For example, an EMC array is accessible by the /dev/vx/rdmp/c2t13d0 path on
node A and by the /dev/vx/rdmp/c2t11d0 path on node B.
