/c x /u x set ignoreECC=on|off
This feature only applies to 9000 series controllers.
This 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 will fail. When ignoreECC is set to on,
such errors are ignored, and the rebuild will continue. When you use
ignoreECC, a file system check is recommended following the rebuild, to
insure data integrity.
By default, ignoreECC is off.
See Table 8, “Supported Model-Unit Types for ignoreECC,” on page 59
/c x /u x set name= string
This command allows you to name the unit with an arbitrary name. You can
use this name in conjunction with the unit serial number to cross-reference
with the unit. The system does not check to ensure uniqueness of names, so be
careful to assign different names to each unit.
/c x /u x set qpolicy=on|off
This feature only applies to 9750 model controllers and 9000 series SX/SE/
SA model controllers.
This command sets the queue policy of the firmware. If the queue policy is
on, the firmware utilizes the drive’s queueing policy. If any drives do not
support a queueing policy, this policy will have no effect on those drives.
For a spare unit, drive queuing is not meaningful or applicable. When a spare
becomes part of a true unit during a rebuild, it adopts the queue policy of the
''new'' parent unit. Thus, this command does not set the queue policy for the
spare unit type.
Note: Queuing is only applicable for SATA drives.
By default, qpolicy is on .
Example:
//localhost> /c0/u5 set qpolicy = on
Setting Command Queuing Policy for unit /c0/u5 to [on] ... Done.
Note: The unit’s serial number is automatically assigned when the unit is created
and is not changeable.
