Using RAID Manager SLPR security
The Cache Partition feature of the RAID storage systems (XP24000/XP20000 Disk Array and
XP12000 Disk Array/XP10000 Disk Array) supports storage logical partitioning (SLPR), a feature
that partitions the ports and volumes of the RAID storage system. If RAID Manager does not have
SLPR security, then it can operate the target volumes crossing SLPR through the command device.
The purpose of RAID Manager SLPR security is to prevent RAID Manager from operating the volumes
on another SLPR (SLPR#N) through the command device from the SLPR (SLPR#M) that is assigned
to its Host. You can use RAID Manager SLPR Security by defining the command device through
the Cache Partition feature, so that RAID Manager can protect the target volume.
The following example represents the SLPR protection facility.

Specifying the SLPR Protection Facility
When you want to access certain SLPRs on a single Host, use the RAID Manager protection facility
so that the Host can access multiple SLPRs through a single command device. The following outline
reviews the setup tasks for the SLPR protection facility.
1.
Setting SLPR on the command device: The command device has an SLPR number and an
associated bitmap so you can set multiple SLPRs. You accomplish this by sharing a command
device (using ports connected to different SLPRs) by setting the command device through
SLPR#0 (called Storage Administrator) on Remote Web Console.
For example, if the command device is shared with the port on SLPR#1 and SLPR#2, then the
command device will automatically set the bitmap corresponding to SLPR#1 and SLPR#2.
