I have been happily using an AHA-2940 with a SCSI and DAT streamer for
quite a while in a computer room at my Dept. After such a nice experience
I bought two AHA-2940UW and two SEAGATE ST32155W (2 GB).
I replaced the old (2940) card with the new (2940UW) one and simply
appended one of the two new disks. The card was correctly initialized (see
kernel-related syslog later); I low-level formatted the disk, partitioned
it with only one file system and high-level formatted it as ext2.
When I tried to copy all the contents of the old /usr partition (2 GB on
/dev/hdc1) the nightmare began---see errors below (and other types that I
could not dump).
I tried the copy both with:
mount /dev/sda1 /mnt
cd /usr
cp -a . /mnt
and:
mount /dev/sda1 /mnt
cd /usr
tar cvpf - . | (cd /mnt; tar xvpf -)
The copy goes on for about 500-650 MB and then errors begin to appear;
some files cannot be copied, then others are copied correctly, then other
errors again (ad libitum).
Is there any SCSI-guru out there willing to help me?
Thanks a lot in advance.
