Sun StorageTek SL500 Modular Library System - Version All Versions and later
Information in this document applies to any platform.
The server sees the sl24 perfectly fine. A backup using OSB was completed this morning for the Host server. The issue is when I try to do a ufsdump remotely to the sl24 through the host server.
-Developed after sl24 has been working and is still working but the ufsdump will not see the device.
-Yes the sl24 is initialized and in a ready state
-The server is an Oracle/SUN M4000 running Solaris 10

Symptoms

Trying to backup a T2000 server to a tape drive over a network using ufsdump.

When running the command to dump, get the following:  Do not have anything in /dev/rmt.  The SL24 is mounted at /dev/obt0 but it says there is no such device.

ufsdump 0ucf 172.25.206.240:/dev/scsi/changer/c3t500143801403874Fd1 /
