many thanks.

Hi Phillip,

Could you let us know what type of machines is this and device attached on the SCSI?

In case like this usually there is a hardware problem, either the cable, the device itself or the scsi terminator.

regards,
Sandy

Hi Philip,

The above errors are pointing towards device file c0t5d0, can you please check the device connected here ? Is this a tape drive..

Best Regards,
Prashanth

[Phillip Acabado]

yes sir, it is a tape drive..

C1537A 12 GB DDS3 Data Compression Tape Drive

[Prashanth.D.S]

Hi Philip,

If this is a tape drive connected then there should be some hardware issue..i would suggest you to get a HW case registered with HP for further Diags..

Are you able to take backups, do you get any error messages while taking backups ?
Was there any changes been made to the drive ?

Best Regards,
Prashanth

This is not that unusual and could as simple as a necessary cleaning. Run ioscan -fnC tape, obtain the HW address and cross reference with logtool for number of errors within the time stamps at the top of the report.

Attach logtool report
