Re: [Veritas-bu] New tape drives not appearing in /dev/rmt.

Peter,

I would guess that Sean is correct. I don't believe the default st.conf file for Solaris 10 includes support for tape drives that aren't lun 0. From what you show below your tape drives all start after LUN 0 (1, 2, 3, and 4). I'd suggest changing your st.conf entries from this:

name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=2 lun=0;
name="st" class="scsi" target=3 lun=0;
name="st" class="scsi" target=4 lun=0;
name="st" class="scsi" target=5 lun=0;
name="st" class="scsi" target=6 lun=0;

To something like this:

name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=0 lun=1;
name="st" class="scsi" target=0 lun=2;
name="st" class="scsi" target=0 lun=3;
name="st" class="scsi" target=0 lun=4;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=1 lun=1;
name="st" class="scsi" target=1 lun=2;
name="st" class="scsi" target=1 lun=3;
name="st" class="scsi" target=1 lun=4;
<etc...>

Then run devfsadm and see if they're there. You may have to run "update_drv st", or reload the st driver to pickup the changes.

Did you make sure you have /kernel/st.conf and (lpfc.conf if emulex fiber
attached) entries.

I'm not fully up on Solaris 10 at the moment but Solaris 10 does a lot a new
things automatically that solaris 8/9 does not.

Hope this helps
