Your st.conf probably has something like:

name="st" class="scsi"
        target=0 lun=0;

name="st" class="scsi"
        target=1 lun=0;

You need to add lines like:

name="st" class="scsi"
        target=0 lun=1;

name="st" class="scsi"
        target=0 lun=2;

I personally added Luns 1-7 on targets 0-7. That possibly makes boot up
a little slower, but it also means the drives will be picked up almost
regardless of whatever silliness I might pull on the SAN. :-)

        T.

Hi Tristan,


That sounds to be my case as well.

 From the info for the one drive and router that are visible, how can I
identify and add the correct entry for the other tape drive into st.conf
file?

Thanks!

Have a look at your st.conf. I have a MSL 6030, and it attaches to the
FC via a built in SCSI/FC router. That router presents the tape drives
as LUN's
1 & 2, with the controller as LUN 0.

By default, the solaris st only scans LUN 0, but that can be changed in
ST conf.

Regards,
        Tristan.

I'm trying to set up Sun Fire-480R as a new backup server to replace an
old one and in a situation where I'm stuck and thus want to ask here.

I'm running Solaris 8 with all the latest Solaris patches including st
driver patch, etc. & latest SAN Foundation Kit 4.4.9. 

And I have a FC-attached HP MSL 5060 library with 2 LTO-1 drives via
Brocade Silkworm switches.

After installing NetBackup v5.1, I tried following the steps in
MediaMgr_DeviceConfig_Guide.txt but no matter what I tried, I couldn't
have it see both tape drives properly and I believe it's something to do
with sg.conf, sg.links, & devlink.tab files. However, I may be wrong.

I tried all I could try with cfgadm, devfsadm, luxadm, zoning, etc. and
know that I have all the proper connections and the box can see the
library itself but not all the drives.

Anyone experienced similar things and have any advice?


Thank you in advance!!!


- Young
