Hello,
You may be having hardware, device driver  issues, try to verify the 
installation of devices and functionality such as drive order, persistent 
binding, drivers, FC switch logs ( if they are Fiber attached drives)
How about labeling the tape with more verbose switched via cmd line, this 
may yield more clues, other then that, check the all logs.
HTH

Tapes marked FULL imediately






I am running 7.4.3 on a new installation. I am using a DELL PwrEdge 2850 
with a Scalar 24 (2 SDLT320 drives). I am running RHEL5. When I try to 
backup the local filesystem on the server, it loads the freshly "labeled" 
tape and immediately marks the tape as full. It proceeds to load the next 
tape and the same thing......and so on and so on.
Initially I tried using SLES10 as the OS but the EMC support seemed more 
adept at RHEL......so I installed RHEL. Regardless of the OS the same 
problem. The message in the /nsr/logs/daemon.raw file is:

 media warning: /dev/nst1 writing: Device or resource busy, at file 2 
record 1
 nsrd media notice: sdlt320 tape 000001 on /dev/nst1 is full
 media notice: sdlt320 tape 000001 used 0 KB of 160 GB capacity
 nsrd write completion notice: Writing to volume 000001 complete
