We are running NetBackup 3.2GA release on storagetek(9714) library unit
on Solaris 7 server. Out of four drives we have, I get error on these
two drives....

<Date> <Hostname> avrd[16303]: Fatal open error on dlt3 (device 3,
/devices/sbus@a,0/QLGC,isp@1,10000/sg@3,0:raw), errno = 19 (No such
device), DOWN'ing it

This is not a new error, it has been happening for a while.

As you see there are errors with dlt3 and dlt0. I have done search at
SUN, and veritas website but not able figure out how to solve this.

Any help will be appreciated.

THANKS.
