storage systems only)
Module Installation Requirements
To ensure that the HBAs can negotiate I/O paths with the
MSA500 G2 controllers, always install the most recent
firmware for the 4-Port Shared Storage Module, the controller,
and the HBAs:
For HBA firmware upgrade procedures, refer to the
controller documentation that ships with the hardware.
For controller and Shared Storage Module firmware
upgrade procedures, refer to the HP website
(http://www.hp.com/support/proliantstorage).
Installing the 4-Port Shared
Storage Module
CAUTION: In systems that use external data
storage, be sure that the server is the first unit to be
powered down and the last to be powered back up. Taking
this precaution ensures that the system does not
erroneously mark the drives as failed when the server is
powered up.

Selective Storage Presentation
SSP is a controller firmware feature that enables the
administrator to control access from hosts to logical drives on
the MSA500 G2 storage system. The administrator selects
which server host or hosts can access the stored data, restricting
access as needed to assure data integrity and security.
Each logical drive on the HP StorageWorks Modular Smart
Array 500 Generation 2 controller has an access control list that
contains the IDs of the server host adapters that have access to
the drive. If a server attempts to send commands to a logical
drive without access authority, the controller rejects the
command.
4. Install the 4-Port Shared Storage Module.
The configuration utility maps the IDs of server host adapters to
connection names and sets up access control lists for logical
drives based on the adapter IDs.

SSP Hardware Configurations
To configure the hardware for SSP, use SCSI cables to connect
each server to the 2-Port or 4-Port Shared Storage Module
installed in the storage system. Boot volumes for individual
servers can reside on server drives or storage system drives.
Enabling SSP
After choosing the configuration that best suits your needs,
enable SSP with ACU Version 7.10 or later. Locate ACU on
the SmartStart CD. For instructions, refer to the HP Array
Configuration Utility User Guide on the Documentation CD.
