Policies file parameters

This section describes the parameters used in the policies file.

The Policy.name header and AppliesTo.1 entry are the only parameters required. None of the values are case-sensitive.

If you do not specify a value for any of the other parameters, they will be assigned a default value when applicable. If a parameter is not valid for a RAID controller, it will be ignored.

In addition to this reference, the ServerGuide Scripting Toolkit also provides two example policies files that you can modify for your own use.

RAID1-5.ini Creates a RAID-1 array using the first two drives, and a RAID-5 array using the remaining drives. It is valid for ServeRAID-4H, 4Mx, 4Lx, 5i, 6i, 6M, 6i+, 7k, and 8i.
RAID5HSP.ini Creates a single RAID-5 array with a single hot-spare drive by using all available drives. It is valid for ServeRAID-4H, 4Mx, 4Lx, 5i, 6i, 6i+, 6M, 7k, 7t, and 8i.
template.ini Provides a policies file template that contains all parameters with details about each one.
syntax.txt Provides a syntax specification for the polices file.

Table 1. Policy file parameters
Keyword	Required?	Default	Description
`Policy.name`	Yes	None	This header designates the start of a new policy. See Policy.name for additional information.
`AppliesTo.n`	Yes	None	Use this parameter to describe when the current policy should be chosen to configure the RAID controllers. See AppliesTo.n for additional information.
`ReadAhead`	No	`ADAPTIVE` (for ServeRAID 4H, 4MX, 4Lx, 5i, 6i, 6i+, 6M, and 7k) `ON` (for ServeRAID-7t and 8i, 8k, and 8k-l)	Specifies the read ahead setting that should be applied to the RAID controller. See ReadAhead for additional information.
`RebuildRate`	No	`HIGH`	Specifies the rebuild rate that should be applied to the RAID controller. See RebuildRate for additional information.
`StripeSize`	No	`8` (for ServeRAID 4H, 4Mx, 4Lx, 5i, 6i, 6i+, 6M, and 7k) `64` (for ServeRAID-7t, 8i, 8k, 8k-l, 7e-SCSI, 7e-SATA, 8e-SATA, 8e-SAS, and LIS-IDEal-RAID)	Specifies the stripe-unit size in KB that the controller should use for its arrays. See StripeSize for additional information.
`Array_Mode`	No	`AUTO`	Defines the array-creation policy to use when selecting physical disk drives to include in an array. See Array_Mode for additional information.
`Array_Defaults`	No	`0%:1` for ServeRAID-8e-SATA and 8e-SAS, LSI-SCSI-RAID when at least 3 drives are available `0%:1` for ServeRAID-4H, 4Mx, 4Lx, 5i, 6i, 6i+, 6M, and 7k, when one or more arrays has 4 or more physical drives `0%:0` for all other cases	Defines the default values to use for the variance and number of hot-spare drives when `AUTO` is specified for `Array_Mode`. See Array_Defaults for additional information.
`Array.letter`	No	None	Lets you specify how many arrays are created and the physical drives that you would like in each array. See Array.letter for additional information.
`Hotspares`	No	None	Defines a list of specific physical drives to designate as hot-spare drives. See Hotspares for additional information.
`Logical_Mode`	No	`AUTO`	Defines the logical-drive creation policy to use when creating logical drives. See Logical_Mode for additional information.
`Logical_Defaults`	No	`FILL:AUTO:AUTO`	Defines the default logical drive settings that should be used when creating logical drives. See Logical_Defaults for additional information.
`Logical.num`	No	None	Lets you specify how many logical drives are created and the specific parameters for each logical drive. See Logical.num for additional information.
