Our configuration is:

StorageTek SL500 library
Server - Solaris 10, Networker 7.2.1, 4 SCSI attached LTO-2 drives and 1
SDLT drive
Storage Node - Windows 2003, Networker 7.2.1, 2 SCSI attached LTO-2
drives

We sometimes get the following errors during writing, cloning and
recovering when the drive is trying to position the tape.  

03/24/06 08:08:48 nsrd: media info: loading volume 100082 into
rd=tor-prdbkp-s01:\\.\Tape0
03/24/06 08:11:20 nsrd: media warning: rd=tor-prdbkp-s01:\\.\Tape0

03/24/06 08:17:41 nsrd: media info: suggest mounting 100083 on
tor-prdbkp-s01 for writing  to pool 'WZero Clone'

This causes the tape to be marked full before it has reached its
capacity or we are unable to recover.

We have updated the firmware on the SCSI card, drives and updated the
SCSI driver.  

Can anyone suggest what we should try next.
