Hi,
It would be nice if I could read a tape written in tar format with a
blocking factor of 200b (100k). The tape drive is a Quantum DLT-4000
(tk-88?).
Apparently the tz driver does not want to read anything beyond 64k.
On the other hand, I can read the large blocks directly using 'scu'.
Trying just a 'read()' call to the tz driver results in 65536 bytes being
read, even if I request more (no error code).
All this on a 1000A server, DUnix 4.0, with the tape drive as a single device
on an extra narrow SCSI card (machine also has the onboard SCSI and
a 3 channel RAID).
I have to do this just once, so every hack, etc. would be most welcome.
The goal is to get about 3G to the disk somehow. I have about 15G available.
Moving the tape drive to an other machine is only a last resort (but
Solaris 2.4 probably can handle it -- did that with an exabyte tape).
Thanks,
Gyula
