Description of Error:

The device is in a condition where it requires action on the part of the
device driver or a human operator.

Probable Cause / Recommended Action:

The device has been reset by a Bus Device Reset message, a hard reset
condition, or a power-on reset.

If this is the case, no action is necessary.

Alternatively, a removable medium has been loaded or replaced.

If this is the case, no action is necessary.

Alternatively, the mode parameters, microcode, or inquiry data for the
device have been changed.

If this is the case, no action is necessary.

Alternatively, the installed version of the device driver does not match
that of the installed version of HP-UX. Install the correct version of the
driver.

In the syslog contents I find the following message:
May 23 15:26:59 L2000_cn vmunix: SCSI: Resetting SCSI -- lbolt: 196686456, bus:
5
May 23 15:26:59 L2000_cn vmunix: SCSI: Reset detected -- lbolt: 196686456, bus:
5
and from May 1 this message shows several times each day.

But my application on the disk array is ok now

The attachment is the syslog file.

So I want to know what's the matter.
Thanks

Hi,

Check this hardware path. 0/7/0/1.9.0

# ioscan -fnkCdisk

# diskinfo /dev/rdsk/cxtydz

Is it still available ?

Regards,
Robert-Jan

Hi

This means the SCSI bus is constantly resetting as its being upset by "Disk at hardware path 0/7/0/1.9.0 : Software configuration error" as Robert suggested start checking the disk.

If you type lbolt in the search box at the top of the page you will find lots of threads to similar problems

:-) John.

Here is the check message
# ioscan -fnkCdisk

diskinfo /dev/rdsk/c5t9d0

Is the disk ok?

And I find another disk /dev/dsk/c5t8d0 has the same problem.
This server use SCSI line connected to Disk Array.

hi,

it is probably a scsi reset since the disk is now claimed. do this to confirm condition of disks:

# dd if=dev/rdsk/c5t9d0 of=/dev/null bs=256

break the above command after about 5 minutes, check if the input and output are the same. if same, it should be alright. do this for the other disk as well

regards.
