Hi,

Setup consists of M2500 ATL library with 4 drives and 8slots connected
in a SAN.
Netbackup Server is Sunfire 280R with Solaris 8 and Netbackup 4.5, still
no maintainance pack installed.
When fired a backup, the backup happens on all the drives and suddenly
few drives marks it as down. When checked in /var/adm/messages, I was
able see
some "Loop OFFline" as below.
Is it causing a problem ????
OR can someone suggest when Netbackup marks the Tape Drive down ????



# tail -f /var/adm/messages
