An Sun Enterprise[TM]450 contains the src/p hardware raid card. The card
is fully functional and all Logical Storage Units are optimal.
However, every time the system is rebooted, the messages file
will log multiple warnings and resets about the card. A sample
is provided below.
Jan 23 08:41:20 e450-hw dptelog: [ID 274699 daemon.notice] The device at
(0,0,2,0) returned a SCSI status: 2 at Tue Jan
23 08:38:58 2001
Jan 23 08:41:20 e450-hw (Error count is equal to the crash drive threshold)

Jan 23 08:41:20 e450-hw dptelog: [ID 993447 daemon.notice] The device at
(0,0,2,0) returned request sense at Tue Jan 23
08:38:58 2001.

Jan 23 08:41:20 e450-hw 70 00 05 00 00 00 00 18 00 00 00 00 24 00 00 c0 00 02
Jan 23 08:41:20 e450-hw dptelog: [ID 785029 daemon.notice] Bus reset occurred
on channel 0 - Command from host requested that the bus
to be reset at Tue Jan 23 08:38:58 2001.
Jan 23 08:41:20 e450-hw 70 00 06 00 00 00 00 18 00 00 00 00 29 02 00 00 00 00

Resolution

The warning messages have no impact on the Logical Storage Units or
access to data. As previously stated, everything is optimal. There are
two repeating sense data strings in the messages file. They are ->
70 00 05 00 00 00 00 0a 00 00 00 00 24 00 0a cd 00 02
^                                                         ^   ^
|                                                         |   |
Sense Key                                                 ASC ASCQ
Sense Key 05 = ILLEGAL REQUEST, ASC/ASCQ 24 00 = INVALID FIELD IN CDB.
This occurs anytime a SCSI command is issued that the firmware doesn't use.
In this case, a LOG SENSE command "4d 00 4e 00 00 00 00 00 28 00 00 00" was
issued . The card's firmware does not support ALL SCSI commands, identified
it as such and continued. The other message ->
70 00 06 00 00 00 00 0a 00 00 00 00 29 02 02 00 00 00
^                                                         ^   ^
|                                                         |   |
Sense Key                                                   ASC ASCQ
Sense Key 06 = UNIT ATTENTION, ASC/ASCQ 29 02 = SCSI BUS RESET OCCURRED.
Multiple illegal requests,(the LOG SENSE data) are being sent to the card.
Once again, these are commands are not applicable to the card. Eventually,
the application stops sending the LOG SENSE, a RESET of the bus is issued,
and the bootup continues. This behavior is normal and may be ignored.
The messages may be turned off. With rev 2.0 of dptmgr, the "display
threshold" was changed. Instead of reporting status changes only (level 4),
it now reports ALL soft errors (level 1). This results in many typical
SCSI commands being logged. This may be turned off from the GUI as follows:
1. /opt/SUNWhwrdg/dptmgr   (start the GUI)
2. Pick Options -> Event Broadcast Control (spawns a new GUI)
3. Change the Display Threshold from 1 to 4.
4. Hit the "OK" button.
5. Hit "OK" to the final display sending the changes to the Broadcaster.
