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

Interesting... I just noticed that you mention you're using Solaris 8
on this host. Do you know if you have the st patch that provides IBM
LTO3 drive support? A quick way to check is to run "strings
/kernel/drv/sparcv9/st | grep LTO", and see if IBM Gen 3 LTO is listed.

Thanks for the thought, but my st.conf already has those entries.
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;
...
continuing through target=15.
