NBU not seeing tape drives

Hi all, I have a Solaris 10 client, where the OS sees the tape drives, but sgscan returns nothing. The master host is also Solaris 10. I'm using a StorageTek SL500, with 6 Ultrium tape drives ...

    In 9 out 10 cases, the sg driver needs to be rebuilt.

    The steps and usage of commands are explained in Device Config Guide as mentioned above.

    These quick steps work in most cases (it's sometimes necessary to add more targets or more luns):

    rebuild the sg driver:
    # cd /usr/openv/volmgr/bin/driver
    # /usr/openv/volmgr/bin/sg.build all -mt 15 -ml 1
     
    Install the new sg driver configuration:

    # /usr/bin/rm -f /kernel/drv/sg.conf
    # /usr/openv/volmgr/bin/driver/sg.install
     
    # /usr/openv/volmgr/bin/sgscan tape
