HP Configuring Arrays Reference Manual page 85

•
If the value of the ClearConfigurationWithDataLoss (on page 82) option is Yes, you can use
the Drive option to remove drives from an array.
Determine which mode to use:
•
Auto method mode—ACU configures all the available drives on the controller into one array. If the
drives are of different capacities, ACU determines the capacity of the smallest drive and uses the same
amount of space on all other available drives.
•
Custom method mode—To specify the drives to be used in the array (different arrays on the same
controller can use different methods), choose one of the following methods:
To specify individual drives, use the applicable convention (port:ID, box:bay, or port:box:bay).
o
To specify only the number of drives to use (not which specific drive IDs to use), enter that number
o
as the value for this option. For example, if you enter drive=3, ACU uses the first three available
drives to build or expand the array that you define in the remainder of the script. ACU 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
o
using this method cannot have a spare.
DriveType
This option specifies the interface type for drives that ACU 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.
Join
To use the Join command, observe the following requirements:
•
The system must be offline.
•
The -offline command line flag must be set when you start ACU Scripting.
The command fails if the OS reports that any of the volumes involved in the join are in use.
CAUTION: Executing the Join command on an online system can result in kernel panics, blue
screens, and/or data loss.
The Split command converts a RAID 1 or RAID 10 logical volume into two RAID 0 logical volumes. The
Join option reverses the splitting process by recombining the two RAID 0 volumes into a single RAID 1 or
RAID 10 volume, depending on the number of physical disks.
For this process, ID is the ID of the resulting volume that was joined. All data on the other volume is lost.
Array = C
Join = A
After the command executes, Array C is removed, and its physical drives are now a mirror of the drives in
Array A. The original contents of Array C are lost.
OnlineSpareMode
The value for this option specifies the behavior of the spare drives when they are activated.
