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.

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.

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.

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.

IMPORTANT: During incompatible version cloning, the storage system

does not reset the updated controller if the controller is operating and

processing I/O. In this case, the storage system does not enter

redundant mode and provides an informational message on the

controller display. To configure redundancy, cycle the storage system

power.
