Here are the steps you will want to perform after the new drives show up in /dev/rmt.
go to dir
/usr/openv/volmgr/bin/sg.build all -mt 15 -ml 15

then if the files are touched remove this file
to attach all drives to sg driver do this command
then check with sgscan tape and if you see the drives with sgscan tape you can then configure robot and drives for netbackup. If you do not see the drives with this command you will not be able to get next step to work.
to see that sg has attached to the drives run cmd:
If the drives show up you can then run the device wizard against the master or media server or run “tpautoconf -a” from the volmgr/bin dir
