Unit Object Commands
www.lsi.com/channel/products 83
/cx/ux set identify=on|off
This command requires a supported enclosure. For additional information
about enclosure-related commands, see “Enclosure Object and Element
Commands” on page 109.
The /cx/ux set identify command allows you to identify a unit within an
enclosure by blinking the LEDs associated with the drive slots of the specified
unit.
Example:
//localhost> /c0/u0 set identify=on
Sending Identify request for unit /c0/u0 to [on] ... Done.
/cx/ux set ignoreECC=on|off
The /cx/ux set ignoreECC command allows you to set the ignoreECC policy
for a given unit.
When ignoreECC policy is set to off, if a rebuild process encounters bad
sectors on the source disk, the rebuild fails. When ignoreECC is set to on,
such errors are ignored, and the rebuild continues. When you use ignoreECC,
a recommended practice is to run a file system check following the rebuild to
insure data integrity.
By default, ignoreECC is off.
/cx/ux set name=string
The /cx/ux set name command allows you to name the unit with an arbitrary
name. You can use this name with the unit serial number to cross-reference
with the unit. The system does not check to ensure uniqueness of names, so be
sure to assign different names to each unit.
Note: The unit’s serial number is automatically assigned when the unit is created
and is not changeable.
