Managing Logical Drives; Checking Logical Drive Configuration; Creating A Logical Drive - HP Surestore Disk Array 12h - And FC60 System Administrator Manual

Managing Logical Drives

An important part of managing the disk array involves defining and maintaining the optimal logical drive
structure for your system. Your system requirements and limitations will influence the logical drive
structure you choose.
Managing logical drives is a part of the overall task of managing disk array capacity. For more information
on managing disk array capacity to meet your system needs, refer to the HP SureStore E Disk Array 12H
User's and Service Manual.

Checking Logical Drive Configuration

When you are managing logical drives, you may find it convenient to check the current logical drive
configuration and the available capacity.
To check the current logical drive configuration and the available capacity, type:
arraydsp -l [LUN] <array-id>

Creating a Logical Drive

Only capacity assigned to logical drives is visible to the operating system. When selecting the size for your
logical drives, consider the following factors:
Any size limitations imposed by the operating system.
Your backup strategy. If you do unattended backup to a device such as a tape, you may want to avoid
creating a logical drive that is larger than the capacity of the tape media. This allows you to back up an
entire logical drive without changing tapes.
NOTE! Before creating a logical drive, check your operating system documentation for any
additional information or steps that may be required to create a logical drive.
To create a logical drive, type:
arraycfg -L LUN -a Capacity <array-id>
LUN must be an unused value between 0 and 7
Capacity must be less than or equal to the currently available unallocated capacity
