Logical Drv Changes - HP Surestore Disk Array 12h - And FC60 Service Manual

Logical Drv Changes

The Logical Drv Changes menu enables you to change logical drive parameters for the array. A logical
drive is a portion of the array capacity that appears to the operating system as a physical disk. Each logical
drive corresponds to a SCSI Logical Unit (LUN) zero through seven. However, the data contained in each
logical drive is distributed across all disks in the array, so there is no correlation between a logical drive
and a single disk in the array.
The entire array capacity can be divided into up to eight logical drives. Only capacity that has been
assigned to a logical drive is available to the operating system. Unassigned capacity is used to increase the
array performance or may be used during a rebuild operation.
Create L-Drv
CAUTION! Deleting a logical drive (LUN) destroys all data on the logical drive. Before
deleting a logical drive, make backup copies of the files you want to save or move the files
to another logical drive.
Delete L-Drv
CAUTION! Before renumbering a logical drive, you should know the impact this will have
on the operating system. After you renumber a logical drive, make sure you perform the
necessary steps to configure the renumbered logical drive into the operating system.
Renumber L-Drv
Creates a logical drive (SCSI LUN) number 0 to 7 with a capacity size
of 100 Megabytes to a maximum of the total remaining capacity
available in the array. Logical drives may be created any time disk
space is available (or becomes available). Creating a logical drive
makes the specified disk capacity available to the operating system.
After creating a logical drive, you must configure the logical drive into
your operating system to use the capacity.
Deletes a logical drive (SCSI LUN) number 0 to 7. When you delete a
logical drive, its capacity is added to the unallocated capacity of the
array.
Renumbers any logical drive (SCSI LUN) number 0 to 7 to any logical
drive (SCSI LUN) number 0 to 7. One reason for renumbering a logical
drive is if you want to swap logical drive 0 with another logical drive
you want to serve as the system boot drive.
