I/O hardware probe timed out at path 0/3/0/0. or relative to it

[Linda Lux]

PC desktop set up with telnet to HP, 11.23 OS.
I run 2 telnet sessions for fbackup, and
while sessions running, if I open up Internet Explorer on the same PC, the telnet sessions will freeze, and the above error occurs in the syslog for both tapes drives.
fbackup hangs (needs a reboot of server) along with an /sbin/ioscan -F
What on the network needs to be looked at or what on the PC desktop needs to be looked at?

IMHO this is not related to your PC or network, most likely a hardware problem on the server. Any messages in syslog or MP log?

[Linda Lux]

this only occurs when the PC is used to open up Internet Explorer.
this is the errors in syslog.log

What is on 0/3/0/0?

# ioscan -fn

It would be a dramatic miracle if IE could crash a server that way ... ;-)

I have 2 DLT tape drives - one at 0/3/0/0 and one at 0/9/0/0.

Again, this error only occurs if the PC is used to open up Internet Explorer.

If the 2 session run without any interference, the backup runs to completeion

[Linda Lux]

its not crashing the server, it is just hanging the fbackup process.

[Torsten. · Accepted solution]

So it would be a good idea to start fbackup in background or start from console. IMHO the first choice is better.

Shalom,

Lots of things can cause fbackup to appear to hang.

Backing up a large file for example can make you think it is hung off.

There is really no relationship between how a PC acts and how HP-UX systems act. Yes they use some common hardware components, but that is where the similarity ends.

I think there may be an unterminated scsi problem here on the indicated I/O path.

I would run cstm/mstm/xstm and probe the hardware and look for faults.

it only happens when the PC is used to access the Internet. If the PC is not used for that, the fbackups run to completetion.
