How to find scsi_id in san

[Charles THISE]

Hi,

I work with a san with multiple host type on.
The end devices are tapes to backup.
my clients are either IBM RS/6000 or HP HP-9000.
On AIX, i can get the scsi_id of all tape rmtXX, by lsattr -El rmtxx

How can i get the same return for the same tape seen by HPUX ?
lssf /dev/rmt/5m give me something, but i can't translate...

I just want something like this :
scsi_id 0x113e1 SCSI Id (ALPA)

Any ideas ?

In advance, i thank you for your help.

Charles.

Hi,
Try ioscan -fnkCtape and find Hardware Path. I do not know your SAN configuration but I think the tape(drive rather) shoudl be seen as device (not as LUN) so the second latest number in hardware path should indicate SCSI id.

Later,

PS. Give me ioscan result.

Marcin,

You don't want to use the "k" option because it will just scan the kernel data structures and not the IO cards.

Charles,

You aren't going to get something like this :
scsi_id 0x113e1 SCSI Id (ALPA)

but more like this:

[root]pbctst: ioscan -fnCtape

Hi Harry,
Yes, you are right, but I assume an ioscan (without k option) or a reboot were performed before.
