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. All values are case-insensitive.

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 is ignored.

In addition to this reference, ServerGuide Scripting Toolkit also provides the following sample policies files that you can either use directly or use as the basis for customized policies files.

Arrays are created by using drives that have the same size in MB, which is the default. Each set of drives of the same size are combined into a single array.

Table 1. Sample policies files
File name	Description
default_raid.ini	Creates an AUTO array using drives that have the same size in MB.
RAID0.ini	Creates a single RAID-0 array using all available drives.
RAID1-1.ini	Creates a RAID-1 array using the first two drives and a RAID-1 array using the second two drives. A single logical drive is created using all available space on each array.
RAID1-5.ini	Creates a RAID-1 array using the first two drives and a RAID-1 array using all remaining drives. A single logical drive is created using all available space on each array.
RAID1.ini	Creates a single RAID-1 array using the first two drives.
RAID1HSP.ini	Creates a single RAID-1 array using the first two drives and a single hot-spare drive using the third drive.
RAID5.ini	Creates a single RAID-5 array using all available drives.
RAID5HSP.ini	Creates a single RAID-5 array with a single hot-spare drive using all available drives.
RAID10.ini	Creates a single RAID-10 array using all available drives.
RAID50.ini	Creates a single RAID-50 array using all available drives.
RAID60.ini	Creates a single RAID-60 array using all available drives.
RAID6.ini	Creates a single RAID-6 array using all available drives.
RAID6HSP.ini	Creates a single RAID-5 array with a single hot-spare drive using all available drives.
template.ini	Provides a policies file template that contains all parameters, with details about each parameter.

Table 2. 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 dictate when the current policy should be chosen to configure the RAID controllers. See AppliesTo.n for additional information.
`ReadAhead`	No	`ADAPTIVE` (for ServeRAID 6M) `ON` (for ServeRAID-7t 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 6M) `64` (for ServeRAID-7t, 8i, 8k, 8k-l,)	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 three drives are available `0%:1` for ServeRAID-6M, when one or more arrays has four 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	Specifies 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	Specifies the number of logical drives that are created and the parameters for each logical drive. See Logical.num for additional information.
