Hello to all.....
I have a Sun V880 which currently uses 16 tape drives in a robot controlled by
Veritas Netbackup.
The plan is...to add a further 8 drives, but I'm not sure what changes need to
be made to the /kernel/drv/st.conf file in order for the OS to see them.
We currently have 16 drives as seen below in /dev/rmt

These are visible between 3 separate JNI cards as follows:

The 8 new drives are to be visible down the following, newly installed JNI
card
JNI,FCE, instance #3
/pci@9,700000/JNI,FCE@2
My question really, is what changes do I need to make to the st.conf file, in
order to see these extra drives from this card (on a different pci bus -
(pci@9)
Would the fact that this card is pci@9, mean that I need to add extra lines
for each target, using lun2, in the st.conf file etc ? or am I way off the
mark !?!
Current st.conf is below:
name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=0 lun=1;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=1 lun=1;
name="st" class="scsi" target=2 lun=0;
name="st" class="scsi" target=2 lun=1;
name="st" class="scsi" target=3 lun=0;
name="st" class="scsi" target=3 lun=1;
name="st" class="scsi" target=4 lun=0;
name="st" class="scsi" target=4 lun=1;
name="st" class="scsi" target=5 lun=0;
name="st" class="scsi" target=5 lun=1;
name="st" class="scsi" target=6 lun=0;
name="st" class="scsi" target=6 lun=1;
name="st" class="scsi" target=7 lun=0;
name="st" class="scsi" target=7 lun=1;
Apologies if this seems an obvious question, but this is really confusing me
!
Thanks
Andy Hardy
