i'm having some problems with tapes recently with my HP 5G external.
i saw this first under 2.1.131, upgraded to 2.2.6 but that hasn't
stopped the problem.
modprobe'ing and doing a full dump using cpio works great... dmesg
says:
paride: version 1.04 installed
paride: epat registered as protocol 0
pt: pt version 1.04, major 96
parport0: PC-style at 0x378 [SPP]
pt0: Sharing parport0 at 0x378
pt0: epat 1.01, Shuttle EPAT chip c6 at 0x378, mode 5 (EPP-32), delay 0
pt0: HP COLORADO 5GBe, master, blocksize 512, 2458 MB
my dump script rewinds the tape and does a cpio -i --only-verify-crc
on the dump afterwards, and during this phase, at some random point in
the tape, i get a
/bin/cpio: read error: Input/output error
when this happens, the load spikes and i have to wait about 10 minutes
for the machine to respond to keypresses. in the dmesg there is:
pt0: Request sense before command: alt=0xd0 stat=0xd0 err=0x1d0 loop=600001 phase=208
pt0: identify before command: alt=0xd0 stat=0xd0 err=0x1d0 loop=600001 phase=208
pt0: Request sense before command: alt=0xd0 stat=0xd0 err=0x1d0 loop=600001 phase=208
i tried rewinding and running through again, with the same results,
and after a while the drive gets wedged such that even mt rewind just
hangs there:
pt0: Sense key: 7, ASC: ffffffa0, ASQ: 71
pt0: identify before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: Request sense before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: rewind before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: Request sense before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: identify before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: Request sense before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: rewind before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
pt0: Request sense before command: alt=0x58 stat=0x58 err=0x100 loop=600001 phase=1
any insights? i've tried this with a delay of 1 as well, with similar
results. could this be a bad tape? doesn't feel like that to
me... the messages just look like drive confusion. is there more
information i should try to gather?
thanks,
ian
