Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
If the controller has failed to the extent that it cannot support a local terminal for
FMU, check the host’s error log for the instance or last-failure codes. See Chapter
5, “Event Reporting: Templates and Codes,” to interpret the event codes.
7. Check the status of the devices with the following command:
SHOW DEVICES FULL
Look for errors such as “misconfigured device” or “No device at this PTL.” If a
device reports misconfigured or missing, check its status with the following com-
mand:
SHOW device-name
8. Check the status of the storagesets with the following command:
SHOW STORAGESETS FULL
Ensure that all storagesets are normal (or normalizing if it’s a RAIDset or mirror-
set). Check again for misconfigured or missing devices.
9. Check the status of the units with the following command:
SHOW UNITS FULL
Ensure that all of the units are available or online. If the controller reports that a
unit is unavailable or offline, recheck the storageset it belongs to with the follow-
ing command:
SHOW storageset-name
If the controller reports that a unit has lost data or is unwriteable, recheck the sta-
tus of the devices that make up the storageset. If the devices are OK, recheck the
status of the cache module. If the unit reports a media format error, recheck the
status of the storageset and its devices.
