Compex Systems Advanced SerialRAID Adapters SA33-3285-02 - Manual (Page 269)

force=yes/no
If an array is using a fast-write cache that is failing, you must specify this
attribute as yes to allow the fast-write cache to be disabled.
Hot Spare Pool Creation and Change Attribute
You can specify the following attribute with the -a option when you are using the
ssaraid command with the -C or -H option to create or change a hot spare pool:
minimum_spares(default=0)
This attribute determines the minimum number of hot spare disk drives that
must be in this hot spare pool to prevent a hot spare pool error from being
logged.
Physical Disk Drive Change Attributes
This section describes:
v Change attribute for hot spare disk drives only
v Change attribute for array member disk drives only
v Other change attributes for physical disk drives
Change Attribute for Hot Spare Disk Drives Only
You can specify the following attribute with the -a option only when you are using the
ssaraid command with the -H option to change a hot spare disk drive:
spare_pool (default=pool_A0 or pool_B0, as determined by the network ID)
If you set this attribute, the hot spare disk drive is assigned to the specific hot
spare pool.
Change Attribute for Array Member Disk Drives Only
You can specify the following attribute with the -a option only when you are using the
ssaraid command with the -H option to change an array member disk drive:
spare_pool (default=pool_A0 or pool_B0, as determined by the network ID)
If you set this attribute, the array member disk drive is assigned to the specific
hot spare pool. If the spare_preferred array attribute is set to true for the
array to which this disk drive belongs, and this disk drive fails, a hot spare disk
drive (if available) is selected only from the hot spare pool to which this disk
drive is assigned.
If the spare_preferred array attribute is set to false for the array to which this
disk drive belongs, and this disk drive fails, a hot spare disk drive (if available)
is selected from the hot spare pool to which this disk drive is assigned. If no
hot spare disk drive is available in that pool, a hot spare disk drive is selected
from the default hot spare pool for that SSA loop (Pool A0 or B0). If no hot
spare disk drive is available in the default hot spare pool, a hot spare disk
drive is selected from any other hot spare pool that contains a hot spare disk
drive.
