system hangs on 100BT interface

[Robert Pieters]

I have an E55 (800-series)and I added a disk cabinett A3311A to it.

Now the system hangs at booting on the process

"configuring HP 100BT interfaces". How can I fix this ?

I'm working with HP-UX 10.20.

Hi,
Is it hanging after connecting the disk cabinet?
May be SCSI IDs are not set properly.
I think nothing to do with 100T base interface.

you can press ctrl-\ (control backslash to interrupt the rc scripts, and then check the rc.log and syslog.log to find out what is the problem.

Good luck
Donald

Hello animesh,

After some time the system did not hang after "configuring HP 100BT interfaces" but performs some sort of ioscan. The device-files are made and every disk has it's own scsi-id.

A ioscan -F lasts 30 minutes and scaning the disks in SAM is extremely slow. When we put back the backup on a configured lvol on 3 disks of this disk cabinett, it writes it to 1 disk. After 4 Gb (exact 1 disk) the system crashes.

We have already replaced the scsi-card (A28696A Wide SCSI)

This sounds like a SCSI problem, have you checked the cables and termination?

Hi,
can you post your ioscan output?
Are you sure all disk are behaving normal ?
