System..............: wdkesc1

Summary:
Disk at hardware path 0/1/1/0.1.0 : Software configuration error


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.

power-on reset. If not a reset, then one of the following may have
occurred.
1. A removable medium may have been changed.
2. The mode parameters in effect for this initiator have been
changed by another initiator.
3. The version or level of microcode has been changed.
4. Tagged commands queued for this initiator were cleared by
another initiator.
5. INQUIRY data has been changed.

The disk is at hardware path 0/1/1/0.1.0 and it is a 146GB spindle. Run the following

ioscan -fn and look for the above hardware path and find the disk device path /dev/dsk/cXtYdZ.

diskinfo /dev/rdsk/cXtYdZ check if the size of the disk is there.

pvdisplay -v /dev/dsk/cXtYdZ and see if the LVM info is OK and the volume group this disk belongs

vgdisplay -v /dev/vgXX to check the status of the volume group that contains this disk.

Check the /var/adm/syslog/syslog.log for any errors such as scsi reset as suggested in the errors/possible causes.

This may be a bogus error and you disgnostic can not monitor the large disk correctly. You may need patching for STM and EMS, check for patches.

Shalom,

If this system has no LUN0 presented, it may be picking up the disk array and thinking it is a disk. Since its not a disk it generates this EMS error.

The real solution is to presnt some kind of useful storage as LUN0 and then these messages will be meaningful.

It is clear from the above details that this disk is NOT an array disk. It is a seagate 146Gb LC drive.
