unless there is a BBU (battery backup unit) or UPS (uninterruptable power
supply) installed.
autoverify
attribute enables the autoverify attribute on the unit that is to be
created. For more details on this feature, see “/cx/ux set autoverify=on|off” on
page 59. This feature is not supported on model 7000/8000. On model 9000,
the JBOD autoverify attribute is not persistent (does not survive reboots).
ignoreECC
attribute enables the ignoreECC/OverwriteECC attribute on the
unit that is to be created. For more details on this feature, see “/cx/ux set
ignoreECC=on|off” on page 60. The following table illustrates the supported
Model-Unit Types. This table only applies to setting this feature at unit
creation time. IgnoreECC only applies to redundant units.
For the 7/8000
series, this setting is only applicable during rebuild; it is not applicable
during creation.
name=string
attribute allows you to name the new unit. (This feature is for
9000 series and above controllers.) The string can be up to 21 characters and
cannot contain spaces. In order to use reserved characters (‘<‘, ‘>’, ‘!’, ‘&’,
etc.) put double quotes (" ") around the name string. The name can be changed
after the unit has been created. For more information, see
“/cx/ux set
name=string” on page 61
and “/cx/ux show name” on page 55.
storsave=protect|balance|perform
attribute allows user to set the storsave
policy of the new unit. This feature is only for 9550SX controllers. For more
information, see “/cx/ux set storsave=protect|balance|perform” on page 61.
/cx rescan [noscan]
This command instructs the controller to rescan all ports and reconstitute all
units. The controller will update its list of ports (attached disks), and attempts
to read every DCB (Disk Configuration Block) in order to re-assemble its
view and awareness of logical units. Any newly found unit(s) or drive(s) will
be listed.
noscan
is used to not inform the operating system of the unit discovery. The
default is to inform the operating system.
Note:
If you are adding new drives, add them physically before issuing the
rescan commands. Hot swap carriers are required unless you first power-
down the system to prevent system hangs and electrical damage.
