Re: Syslog message
Check the following
Make sure that the SCSI cabling and termination is OK.
Try increasing the timeout using pvchange.
If still the problem is there,then replace the disk.

Re: Syslog message
Review the timeout of the disk with pvdisplay and refer to the 'IO Timeout' value and to increase it up to 180. The default is 30 so start with something in between.
pvchange -t 120 /dev/dsk/c3t15d2.
I also encourgage you to review LOGTOOL and check for failing devices:
STM > TOOLS > UTILITY > RUN > LOGTOOL > FILE > VIEW > RAW SUMMARY.
Note the first and last dates of transactions and calculate the difference. If the difference is short, like 4 hours, then this is important to note. Now read down the report of hardware addresses and observe the integer numbers in parenthesis. Anything over 150 in this example 4 hour period should be called into HP for replacement.

Re: Syslog message
The device in question is dev: cb03f002. To determine what device this is quickly
# ll /dev/* |grep 3f002
Run ioscan. Look for No_hw, unknown, -l, not claimed, etc.
Check termination, cables, etc. including making sure they are the ones suggested/provided by the manufacturer depending on what equipment you have connected to the machine.
Open another case with HW Support and have them check the firmware of the equipment as well.

Re: Syslog message
The problem this solves is with specific types of hardware, and the output from SCSI-queries being mis-interpreted. This could also occur for devices that are off or improperly removed from active service.
