AAppendix
Storage management logical partitions ( SLPRs)
A disk array can be shared with the multiple organizations and with multiple dep artments within an
enterprise. Therefore, multiple administrators might manage a single disk array. This circumstance creates
the potential for an administrator to destroy volumes of other organizations, and it can complicate and
incr ease the difficulty of managing the disk array.
Use Disk/Cache Partition to alloc ate all resources of one disk array (all ports and CLPRs) to virtual disk
arrays called SLPRs. You can create up to 31 SLPRs in one disk array. Each virtual disk array can be
accessed only by its administrator. This approach eliminates the risk of an ad ministrator destroying
volumes from other organizations and of data leaks am o ng organizations.
In a non-partitioned environment, a full array is co nsidered on e singl e partition SLPR0. After the disk
array is p a rtitioned, SLPR0 becomes the unpartitioned portion of the disk array. Similarly, CLPR0 contains
all parity groups (PGs) and ca che in the non-partitioned environment. After the disk array is partitioned,
CLPR0 contains the remaining PGs and cache that are not allocated to other CLPRs.
Figure 55 Example of an SLPR
Example of an SLPR shows an example of one disk array partitioned into two virtual disk arrays. Each
virtual disk array is allocated to one enterprise. Enterprise A’s disk array administrator can manage
enterprise A’s virtual disk array, but cannot mana ge enterprise B’s disk array. Similarly, enterprise B’s
disk array administrator can manage enterprise B’s virtual disk array, but cannot manage enterprise A’s
disk array.
