HP StorageWorks XP Remote Web Console Software - Manual (Page 14)

In a non-partitioned environment, a full array is considered one single partition SLPR0. After the array
is partitioned, SLPR0 becomes the unpartitioned portion of the array. Similarly, CLPR0 contains all
parity groups (PGs) and cache in the non-partitioned environment. After the array is partitioned, CLPR0
contains the remaining PGs and cache that are not allocated to other CLPRs.
Figure 2 shows an example of when one array is partitioned into two virtual arrays. Each virtual array
is allocated to two enterprises respectively. In this case, enterprise A's array administrator can manage
enterprise A's virtual array, but cannot manage one of enterprise B's arrays. Similarly, enterprise B's
array administrator can manage enterprise B's virtual array, but cannot manage one of enterprise A's
arrays.
IMPORTANT:
Disk/cache partitioning for the SVS200 is limited to one SLPR and four CLPRs.
The virtual array created by the partitioned array is referred to as the storage management logical
partition (SLPR). You can create up to 32 SLPRs, including SLPR0 which is provided as a default in
one array (with the exception of the SVS200). For more information, see
Creating SLPRs .
Figure 2 Example of an SLPR
To create an SLPR, allocate the array's resources (that is, ports and CLPRs). For instructions on allocating
the array's resources, see
Working with SLPRs . To create and manage a CLPR, you need user authority
for the array. For more information, see Partition administration and administrator rights and the
HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000/SVS200.
• Restriction on SLPR and CU group
You cannot allocate array resources belonging to different CU groups to an SLPR other than SLPR0.
