Netbackup on Redhat AS3 connected to a StorageTek L80

[James_Richard1]

When I cat the /proc/scsi/scsi it detects the library.

cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: STK Model: L80 Rev: 0215
Type: Medium Changer ANSI SCSI revision: 03

But it doesn't detect the drives.

scan returns the info on the drives.

./scan

What do I need to do to make the drives show up under scsi devices?

if you can see your changer and drives using robtest then the below should work. Since you are on Linux instead of Solaris you will need to substitute your linux commands for the devfsadm command. Either that or do a reboot -r or whatever works on linux.

Creating sg.conf and getting netbackup to see tapes and changer
modinfo | grep tape
modunload -i #
rm /dev/rmt/*
cd /usr/openv/volmgr/bin/driver
cp st.conf st.conf.old
cp sg.links sg.links.old
cp sg.conf sg.conf.old
rm -f /kernel/drv/sg.conf
/usr/openv/volmgr/bin/sg.build all -mt 15 -ml 15
##comment out old entries/ or delete old entries in st.conf in /kernel/drv/st.co
nf , such as
##name="st" class="scsi" target=0 lun=0;
cat /usr/openv/volmgr/bin/driver/st.conf >> /kernel/drv/st.conf
/usr/openv/volmgr/bin/driver/sg.install
devfsadm -C -c tapes
scan

Hi James,

Check out the "Media Manager Device Config Guide", chapter 7 - Intel Hosts running Enterprise Linux. Hopefully this helps?

I updated the qlogic drivers on the server and it was able to fully detect the Library and drives.

After upgrading the firmware on the Library, drives, and fiber bridge it turned out to be the qlogic drivers that came default with AS3 was the issue.
