Hi all,

Am getting persistent errors below on my hp-ux 11i machine. What could be wrong?

Thank you

Hi,

Check the device and bus which is generating scsi reset. It is not responding to I/O operations. Most propable causes for this error is bad disk, bad controller or improper/defective terminator.

You should look at the devices which are connected to ext_bus 0.

These errors can be due to:

1. The IO timeout setting for the physical disk being set too low
2. A problem with the SCSI connector for that device
3. Not having the latest SCSI patches installed

Check with below commands

ll /dev/dev/* | grep -i 001000

This will give you the disk and its controller.

Contact HP Hardware support for this defective part to get replaced.

Thanks

This is a tape unit. Will check manually and see if thre are any loose connections.

Shalom,

Bad disk or a recent removal of a hot swap disk.

I'd favor bad disk at this point.

If its a hot swap, contact HP hardware support for a replacement.

If its an internal disk, engage them to come handle the replacement, schedule some downtime.
