Qualstar AIT library?
|
|
| Jonathan M. Prigot 2004-06-01, 4:55 pm |
| I am trying to set up a Qualstar library with AIT-3 drives. The default mode
for the drives is "Fixed 512-byte blocks", and the library is connected to
a SCSI card (manufacturer uncertain) using a sym53c875 chip. It responds to
the various mt and mtx commands properly.
If I do a "tar cvf /dev/nst0 .", however, it will list about 10 files on the
screen, the drive activity light will flash and then stop, never to
restart. I changed the drives' switchpack for "variable block mode", but
the same thing happens.
I am hoping that someone has the same or similar configuration who can
provide some guidance.

| Sigh (drain bramage). This is on a Red Hat 9 system with kernel
2.4.20-31.9smp using a Tyan Tiger mobo with dual Athlons.

Well, first, do not use variable block size for AIT drives.
AIT should always use flixed block size, otherwise you will get problems
with dirs and empty files and so on.
FIXED BLOCK MODE for all AIT drives.
