Unable to see medium changer

[Creole-Kid]

**** Moved to new discussion from https://www-secure.symantec.com/connect/forums/unable-see-robotic-media-changer ****

Hi,

I also am faced with NetBackup 7.5.0.5 not seeing the FC connected tape library or drives under Solaris 11.1.  The OS can see the tape drives.  The library connection piggy backs on one of the tape drive fc links.  I have run the 'sg.build all' and 'sg.install' scripts but the results are not successful.  Strangely, the sg.conf file located at /kernel/drv does not change to the new one created by the sg.build script.  The date is correct on the file but it does not contain any of the wwn information.  Any help is greatly appreciated.

sg.build script will only update files in /usr/openv/volmgr/bin/driver.

Check files like sg.links and sg.conf in this folder before running sg.install. 
I have experienced situations where I had to edit above 2 files manually to add device entries before running sg.install.

sg.install will populate /etc/devlinks.tab and /kernel/drv/sg.conf with entries in the usr/openv/volmgr/bin/driver files.

Thank you Marianne!!!!

Your first sentence is what helped me to understand and resolve my problem.

I was running sg.build from within the /usr/openv/volmgr/bin directory.  Therefore, the new sg.conf and sg.links files were created in the /usr/openv/volmgr/bin directory.  Subsequently, the sg.install was copying the files from the /usr/openv/volmgr/bin/driver directory which were never updated.  

I copied the newly built sg.conf and sg.links file to the /usr/openv/volmgr/bin/driver directory and executed the sg.install script.  Voila!!!  Total success!

Thanks again, Marianne
