4.21 Using CCI SLPR Security

The Virtual Partition Manager (VPM) feature of the Hitachi RAID storage systems (USP V/VM
and TagmaStore USP/NSC) supports Storage Logical Partitioning (SLPR), a feature that
partitions the ports and volumes of the RAID storage system. If CCI does not have SLPR
security, then it will be able to operate the target volumes crossing SLPR through the
command device. The purpose of CCI SLPR security is to prevent CCI 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 CCI SLPR Security by defining the command device
through the Web console or the SVP-installed 'VPM' feature, so that CCI can protect the
target volume.
The following example represents the SLPR protection facility.
