CLEAR DEVICE_ERRORS unit command
The CLEAR DEVICE _ERRORS unit FMU command is used:
■ To delete and reinitialize “this controller” silo.
Note: HP does not recommend clearing this event silo.
DS_EVENT_UA The command completed with an error, detailed by the sense
key, ASC, and ASCQ.
Note: It is normal to see a series of DS_EVENT_UA,
sk:06, asc:29, ascq:02 on each device on that port
following a bus reset.
Note: It is normal to see DS_EVENT_UA entries with a code
sk:05, asc:24, ascq:00, depending on the support
level of the drives in the system. These events are in response
to the controller trying to set features not available on all
drives. The response does not indicate a problem or reduced
functionality of the storage system.
DS_EVENT_CMD_TIMEOUT A device did not complete a request in the controller-defined
time limit. The command is aborted and retried. A large
number of occurrences of this event may indicate bus
saturation or a device that is slow responding to commands.
DS_EVENT_BBR Not currently used.
