A variety of commands is available for physically locating specific hard drives.
Specifically, you can locate all drives attached to the MSA1000, all drives in a
specific storage enclosure, all drives on a specific SCSI bus, all drives in a specific
LUN, or a specific individual hard drive.
When these commands are executed, the LEDs of the requested drives will blink.
These LEDs are visible from the front of the MSA1000 and its attached storage
enclosures.
Note: If a time limit is not included with the Locate command, the LEDs will blink for 30
seconds.
The basic command verb is LOCATE, but a variety of command nouns and
command options are available to customize the request.
