The disk id breakdown is actually slightly wrong:
- ...
/disk
is obvious
@
separates the device address (.../disk
from the device identifier)
w
for this disk device type indicates the device identifier is a WWN
32a6b2f6484021d2
is the full WWN of the disk device
,0
is the LUN number.
:a
is the partition.
The full WWN is 32...
- however, if this is different than what show-volumes
is showing you, then I assume this is one path of a multi-path connection to the disk (for example, a storage array with multiple fibre connections to the same SAN could present the same disk with different WWNs on each storage array SAN connection). The show-volumes
output shows the volume WWN, as opposed to the WWN of the path to get to that volume.
Followup:
From the Oracle documentation, it appears that this WWN value appears in the output from probe-scsi-all
. Their example is:
ok probe-scsi-all
