Value
Specifies the Write Cache percentage. This option is not required. If this option
is not specified, the Read/Write cache ratio remains unchanged.
This value is a numeric value from 0 to 100. It must form a valid read/write
cache ratio that is supported on the controller with the ReadCache option.
Specifies the Rebuild Priority. This option is not required. If this option is not
specified, the Rebuild Priority remains unchanged.
• Low
• Medium
• High
Specifies the Expand Priority. This option is not required. If this option is not
specified, the Expand Priority remains unchanged.
• Low
• Medium
• High
Specifies the Surface Scan Delay in seconds. This option is not required. If this
option is not specified, the Surface Scan Delay remains unchanged.
N: This value is a numeric value between 1 and 30 seconds.
Specifies the SSP State for controllers that support SSP that is enabled/disabled
on a controller basis. This option is not required. If this option is not specified,
the SSP State remains unchanged. Currently, only Fibre and shared-storage
controllers support SSP. This command is not valid for the RA4x00 controller
because RA4x00 controllers support SSP that is enabled/disabled on a logical
drive basis.
• Enable: Enables SSP for the controller.
• Disable: Disables SSP for the controller.
SSP only remains enabled if the SSPAdaptersWithAccess command specifies
an adapter for one or more logical drives. If no adapters with access are specified
for any logical drives, the SSP State reverts back to disabled.
Specifies the preferred path mode when redundant array controllers are in an
active-active configuration. This option is only available for certain redundant
array controllers. If the option is not specified, it remains unchanged. This option
is ignored in active-standby configurations. This option is optional.
• Auto: This is the default value. The array controller automatically determines
which logical drives are assigned to each active array controller for I/O. The
array controller dynamically load balances the logical drive paths.
• Manual: Manually specify which logical drives are assigned to each active
array controller for I/O. The array controller does not change the paths. The
paths are specified using the PreferredPath command in the LogicalDrive
section.
Specifies the Array ID.
[A-Z,a-f]: In Configure mode, a new array is created. The array letter specified
must be the next available array letter in the existing configuration. In
Reconfigure mode, the array letter can identify an existing array, or it can identify
the next available array letter in the existing configuration to create a new array.
