I would do the following :

>From sun server run : I have netbackup running on AIX servers . 

1) robtest -mount a scratch tape into one of the drives .
2)run a tar back to the tape of /tmp- if the tar backup is successful
then the OS and drives are fine - move to the NetBackup part.
3)Go back to the Library and write down S/N of the drives .
4)run NetBackup scan command and print the output .
5)match the S/N of the drives and scan out put and see the drive order
i.e. 1 2 3 4 5etc..
6)Run tpconfig  -and configure drives and robot in NBU.  There tpautocnf
command too but it messes up drive numbering.its in
/usr/openv/volmgr/bin. 

                       WARNING                                
                                                              
The Media Manager device daemon is active on this machine.    
If any device changes are made, the daemon must be            
stopped and restarted for the changes to take effect.         
To do this enter:                                             
    /usr/openv/volmgr/bin/stopltid                            
    /usr/openv/volmgr/bin/ltid <args>                         
                                                              
Press any key to continue or CTRL-C to terminate tpconfig     
                                                              
That's the clean way I know and use .

Subject: Re: [Veritas-bu] DLT drives going down

Im seeing Drive downs on my systems using fibre. They seem to have
dissapeared from 2 of the media managers also.

running netbackup 5.0 mp4 with Sun L700 library 5 LTO2 drives, 3 of
which are shared SSO option to 2 other media servers.

All connected via a san switch ( what type i dont know as its in a
remote site and i didnt install it ). I know the drives are zoned
somehow and the wwn's for devices are in /kernel/drv/sd.conf. Everything
was working fine and now some devices cant be seen when running cfgadm
-al it says failing..

Storedgetek have been out to check drives and say they are fine , yet
every day my script notes 2 going down and brings them backup. It was
just one of the shared drives now it has moved to 2 so all my ITC fails
for the media servers.

I have been trying to run cfgadm to reconfigure but i cant seem to get
the syntax right

:(
