SSA CLI 55 modify drives=[#:]#:#-[#:]#:#where is an array, and the specified physical drives are the new destination for the array.For example, in an existing array, three 72-GB SAS drives (1e:1:4-1e:1:6) are the source. Another drive of thesame size is the spare (1e:1:9). With all criteria met, you can move the array to three different 72-GB SASdrives by specifying the new destination drives in the command (1e:1:12-1e:1:14). To maintain the samespare drive, be sure to designate the spare drive for the moved array.Example commands:=> array a modify drives=1e:1:12-1e:1:14=> array b modify drives=1c:1:6-1c:1:7Replacing an arrayYou can replace an array by designating different physical drives for the array. To replace the array, each ofthe physical drives where the array will reside must meet the following criteria: The destination drives must all be the same type (for example, SATA or SAS), but do not have to besame type as the drives in the source array. A destination drive does not have to be an unassigned drive, but if it is assigned, it must be a driveassigned to the array being replaced. The destination drives must have sufficient capacity to hold all the logical drives present in the sourcearray.Like array creation and expansion, the useable space in all drives is reduced to the size of the smallestphysical drive in the destination disk set.Replacing an array automatically removes any previously assigned spare drives. If spares are assigned to theexisting array, they must be designated for the array when it is moved.Syntax: modify drives=[#:]#:#-[#:]#:#where is an array, and the specified physical drives are the new destination for the array.For example, in an existing array, three 72-GB SAS drives (1e:1:4-1e:1:6) are the source.

Each array contains one physical drive andone RAID 0 logical drive.Example command:=> ctrl slot=1 create type=arrayr0 drives=allunassignedExtending a logical driveIf the operating system supports logical drive extension, you can use any unassigned capacity on an array toenlarge one or more of the logical drives on the array.IMPORTANT: An array expansion, logical drive extension, or logical drive migration takes about15 minutes per gigabyte. While this process is occurring, no other expansion, extension, ormigration can occur simultaneously on the same controller. Controllers that do not support abattery-backed write cache do not support this process.
