Hello,

This is my config:

SunOS lau-backup2-b 5.9 Generic_117171-05 sun4u sparc SUNW,Sun-Fire-280R
Patch: 113277-24 SunOS 5.9: st, sd and ssd Patch
Sun StorEdge(TM) Enterprise Backup 7.2.Build.172 Network Edition/35
Storagetek Library L80 with Quantum SDLT320 drives firmware rev 80, SCSI LVD

I often get the following messages:

/nsr/logs/daemon.log:

07/20/05 01:32:41 nsrd: media notice: sdlt320 tape DEX066 on /dev/rmt/0ubn is 
full
07/20/05 01:32:41 nsrd: media notice: sdlt320 tape DEX066 used 28 GB of 160 GB 
capacity
07/20/05 01:32:59 nsrd: media notice: Volume "DEX066" on device 
"/dev/rmt/0ubn": Block size is 32768 bytes not 131072 bytes. Verify the device 
configuration. Tape positioning by record is disabled.

/var/adm/messages:

It can happen on any drive and with new or used tapes. The tapes are labeled 
always the same way.
I know that this is a known issue, but nobody (Sun, Sunmamagers, Google) has 
been able to provide a solution yet.

TIA for your replies
