Hi,
I'm having problems to configure my tapes on my Media Server Solaris 10 using Netbackup 7.1.
Master Server: Netbackup 7.1 for Linux (Red Hat 5)
Media Server: Netbackup 7.1 for Solaris (Solaris 10)
Tapes: LTO-4 with SSO.
I upgrated my HBA drivers today and after that I can't run backup normally.
I found one TECH NOTE about that, but I'm not confortable to execute that http://www.symantec.com/docs/TECH61591.
Please, someone can help me wth this problem?
Can I do what this Tech Note suggested?
Thanks

Please share output of /usr/opemv/volmgr/bin/sgscan on Solaris media server.
It is quite normal on Solaris media servers to need to rebuild the sg driver (the NBU pass-thru driver) after changes are made at OS/SAN/hardware level.
First of all - verify that ALL devices in /dev/rmt are valid.
Does 'ls -l /dev/rmt/*cbn |wc -l ' correspond with the number of physical tapes drives?
If not, cleanup device tree and start from scratch:
cd /dev/rmt
rm *
devfsadm
ls -l *cbn (verify that correct number of drives are seen; make a note of targets and luns)
Rebuild sg driver as follows:
cd /usr/openv/volmgr/bin/driver
/usr/openv/volmgr/bin/sg.build all -mt <targets> -ml <luns>
/usr/bin/rm -f /kernel/drv/sg.conf
/usr/openv/volmgr/bin/driver/sg.install
/usr/openv/volmgr/bin/sgscan tape

Don't follow the technote.
Rebuilding the sgdriver should not be too hard, mail me if you need help. (martin<underscore>holt@symantec.com)
It might be that the drive is configured via wwn as opposed to lun and target, in which case you need only run sgbuild all
As marianne shows, cd to the /usr/openv/volmgr/bin/driver
dir before running the sgbuild command (else the sg.build/ links file are created in the wrong dir.
I would copy the existing sg.build/ links files first. Before you can run sg.install, you will have to move the file /kernel/drv/sg.conf
I also unload the sg driver, not sure if you have to do this, I will check
Please note, I am quite busy tomorrow, so I may only be able to send some details via email.
Please send me contents of:
/usr/openv/volmgr/bin/driver/sg.conf and sg.links
cfgadm -al -o show_FCP_dev
ls -al /dev/rmt/0*
/usr/openv/volmgr/bin/scan
PLease also ensure that the os can see the drive, it has a /dev/rmt file(s) and you know which drive it is (if you have more than one) referring to it's serial number and wwn.
