- You can read (and write) a tape in any blocksize regardless of
- how it's set in SMIT using tctl, like in
- tctl -p 5120 -b 1024 -f /dev/rmt0.1 | tar -xvf -
-
- Our 8mm drive is set to blocksize 512, the installation release
- notes say this is required for mksysb. But this make your 8mm drive
- into a 1.1 GB drive!
-
- So I use tctl with cpio tar and backup to make sure I can go to 2.3GB.
