128 HP StorageWorks LUN Configuration Manager XP: user’s guide
Configuring new volumes
To configure new volumes:
The Logical Device ID Configuration window opens.
1. Select the incomplete parity group (group status displayed as ------), and
select the desired LDEV ID assignment scheme:
Linear Assigns the LDEV IDs in sequential order for all
unassigned logical addresses within the parity group.
The Linear option is appropriate for users who
actively balance their disk array work loads.
Disperse Randomly rotate the LDEV IDs among multiple
groups across the subsystem, eliminating hot spots
and improving data access. The Disperse option is
appropriate for users who do not actively balance their
disk array work loads.
Detail Allows manual selection of LDEV IDs.
