I'm not exactly sure how to frame this question, however I am having a difficulty when using ufsdump to dump a very large partition (1.2TB) over the network to a DLT-S4 library hosted on a SLES 10.1 machine (Sun Fire V40Z). I have tried just the standard ufsdump call:
ufsdump -0ulf 172.16.20.209:/dev/nst0 /dev/nst0
This appears to work,
Dump started: 2008-09-18 16:10:57
DUMP: Date of this level 0 dump: September 18, 2008 4:10:57 PM NDT

DUMP: 2302541054 blocks (1124287.62MB) on 1 volume at 14965 KB/sec
DUMP: DUMP IS DONE
DUMP: Level 0 dump on September 18, 2008 4:10:57 PM NDT
Dump completed: 2008-09-19 13:33:47
However, the the tape can only hold 800GB, which makes the fact that it worked seem unfeasible. When I try to restore from the tape, I get this:
-bash-3.00$ /usr/sbin/ufsrestore -if 172.16.20.209:/dev/nst0
read: Cannot allocate memory
Media read error: Not enough space
If I attempt to set the tape specifications, as provided by Quantum:
Blocking Factor (b): 256KB / 1024-byte units = 512
Bits per inch (d): 256K (256000 or 262144?)
Size of tape in feet (s): 2100
# of tracks (t): 1280 (2988 tracks/inch)
/usr/sbin/ufsdump -0ulbdstf 512 256000 2100 2988 172.16.20.209:/dev/nst0 /san/model-output
However, upon execution, it calculates that ~400 tapes are needed:
-bash-3.00$ /usr/sbin/ufsdump -0ulbdstf 512 256000 2100 2988 172.16.20.209:/dev/nst0 /san/model-output

^C DUMP: Interrupt received.
DUMP: NEEDS ATTENTION: Do you want to abort dump?: ("yes" or "no") yes
DUMP: The ENTIRE dump is aborted.
What am I doing wrong? Can anyone point me in the right direction?
Thanks in advance!
