Hello,
as Kurt explained, look at the fiber card adapter instance.
Look under /proc/scsi to find out your adapter type.
In my case, it is /proc/scsi/qla2300.
Under that directory, there will be an instance for each adapter.
In my case, I have 1 adapter. Browse that file. Look for the
"SCSI Device Information" section. In that section, look for the
target devices, e.g,
# cat /proc/scsi/qla2300/1
...
SCSI Device Information:
...
scsi-qla0-target-0=5005076300426c01;
scsi-qla0-target-1=5005076300426c02;
The target-0 and target-1 correspond to /dev/IBMtape0 and /dev/IBMtape1
in my case and the values above are their WWNs, i.e,
device = /dev/IBMtape0, wwn = 5005076300426c01
device = /dev/IBMtape1, wwn = 5005076300426c02
Bye !
