Re: SCSI Errors
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.

Re: SCSI Errors
You should look at the devices which are connected to ext_bus 0.

Re: SCSI Errors
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.

Re: SCSI Errors
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.
