IBM 12/24 DDS3 DAT
The tape drive ate a tape and snarled so it was replaced. I matched the
identical pins. and IDs, termination.
I cannot get a backup now. It keeps stopping after a couple GB with
"Reached end of media..."
the HD is only 4GB so I am not running out of space. This system has
been running fine of a year.
I put yet another tape unit in the system, removed and added the tape
and relinked the kernel. I got ONE backup and then it hasn't worked all
week.
cd /
find . -depth -print | cpio -ovcuB -O /dev/rct0
All help is appreciated
What is the length of the TAPE you are using?
60 meter (DDS1 - ~ 1.3GB)
90 meter (DDS1 - ~ 2.0GB)
120 meter (DDS2 - ~ 4.0GB)
125 meter (DDS3 - ~12.0GB)
150 meter (DDS4 - ~24.0GB) Invalid in a DDS3 drive.
Do a "tape getcomp /dev/xct0" with a tape in the drive.
If "0" or "2", hardware compression is off.
If "3" hardware compression is on and the capacities listed above
would almost double, unless your data is already highly compressed.
tape -a 3 setcomp /dev/xct0 would enable compression.
