I have found and solved the problem by calling Sun for support:
to make data compression from unix command:
# ufsdump 0uf /dev/rmt/0ubn
# vxdump -0uf /dev/rmt/0ubn
that's it and it solved my problem.
Thanks! to everyone who responded...
attached mail follows:
I have a brand new L280 tape drive with 8 slots in it. I attached it
a UE3500 running OS 2.6 with Recommanded patches and left it with the
setting. I wrote a script to do the backup of about over 35Gb of data
to that L280
tape drive. I have two problems with it and need to be corrected:
1) When I run a script, the backup won't fit on one tape, it request to
second tape, but the tape drive won't unload the tape itself. I
have to unload
it by hand. How do I make it unload the tape and load the next
one by itself
with data compression?
here is command I use to do the backup in the script:
for ufs file systems:
# ufsdump 0ucf /dev/rmt/0cbn
for vxfs file systems:
# vxdump -0ucf /dev/rmt/0cbn
2) When I try to set the compression from OFF (default) to ON and saved
from the configuration menu on the drive, it won't stay ON, it
itself back to OFF. Even when I power cycle the tape drive.
Is anyone have some suggestions? Any patches for it? how do I make
the data compress, so that it will fit on one tape?
Thanks! in advanced...
