CachingArray
This option specifies the Caching Array ID.
•In Configure mode, HP SSA creates a new caching array. The value that you specify for the array option must be the next available array letter in the existing configuration. AA follows Z, and BA follows AZ.
•In Reconfigure mode, the array letter identifies an existing array, or it can identify the next available array letter in the existing configuration to create a new array.
Drive
You can use this option in the input file to specify new physical drives for the array. Use this option to build a new array or to expand, shrink, or move an existing array.
Observe the following guidelines:
•If you are expanding an array, each drive that you add must have a capacity no less than that of the smallest drive already in the array. The added drives and the existing drives in the array must all be the same type (for example, SAS or SATA).
•If you are moving or shrinking an array, HP SSA Scripting compares the current drives with the requested drives, and then determines whether you are moving or shrinking. Shrinking or moving an array is supported only in Custom method mode.
•If the value of the ClearConfigurationWithDataLoss (on page 88) option is Yes, you can use the Drive option to remove drives from an array.
Custom method
•To specify individual drives, use the applicable convention (port:ID, box:bay, or port:box:bay).
•To specify only the number of drives to use (not which specific drive IDs to use), enter that number as the value for this option. For example, if you enter drive=3, HP SSA uses the first three available drives to build or expand the array that you define in the remainder of the script. HP SSA automatically determines which drives are suitable to use.
•To use all available drives, enter an asterisk as the value for this option. An array that is configured using this method cannot have a spare.
DriveType
This option specifies the interface type for drives that HP SSA must use to build the array. Choose one of the valid drive types:
[SCSI SAS SATA SATASSD SASSSD]
The value is often used with the wildcard (*) or number argument for Drive.
OnlineSpareMode
The value for this option specifies the behavior of the spare drives when they are activated.
For controllers that support Auto Replace Drive, setting this value to AutoReplace enables a rebuilt spare drive to become a data drive in the array. When the failed data drive is replaced, it assumes the role of the former spare, eliminating the need for a second array rebuild.
