• The controller and its storage are configured using the Storage Management Utility (SMU) or Command Line Interface (CLI). ◦ For information about configuring storage in the SMU, see the HP MSA 2040 SMU Reference Guide or HP P2000 G3 MSA System SMU Reference Guide. ◦ For information about configuring storage in the CLI, see the HP MSA 2040 CLI Reference Guide or HP P2000 G3 MSA System CLI Reference Guide. • (Optional but strongly recommended) Map each volume to ports on the server blades. This is called explicit mapping. Other HP utilities use a similar concept termed Selective Storage Presentation (SSP) or Access Control Lists (ACL). When you set up explicit maps, you specify for each volume, the hosts that can access it. If a new server is installed in the c-Class enclosure, storage volumes will not be visible to that server until explicitly mapped. When you do not set up explicit maps for each volume, all server blades with P711m/P712m controllers that are contained in the same SAS zone can access the storage. If a new server is installed in the BladeSystem c-Class enclosure, the storage volumes will be immediately visible to that server. ◦ For information about mapping volumes using the SMU, see "Managing Host Access to Volumes" in the HP MSA 2040 SMU Reference Guide or HP P2000 G3 MSA System SMU Reference Guide. ◦ For information about mapping volumes using the CLI, see the "Map volume" section in the HP MSA 2040 CLI Reference Guide or HP P2000 G3 MSA System CLI Reference Guide. • When mapping, be sure to choose all MSA controller ports (A1, A2, A3, A4, B1, B2, B3, and B4), to guarantee access in the event of a controller, port, or cable failure. During a failover, if access is granted to all MSA controller ports, I/O will fail over to ports on the surviving controller. • Upgrade to the latest firmware version before connecting to the switch.

(Optional but strongly recommended) Map each volume to ports on the server blades. This is
called explicit mapping. Other HP utilities use a similar concept termed Selective Storage

When you set up explicit maps, you specify for each volume, the hosts that can access it. If
a new server is installed in the c-Class enclosure, storage volumes will not be visible to that
server until explicitly mapped.
When you do
not
set up explicit maps for each volume, all server blades with P711m/P712m
controllers that are contained in the same SAS zone can access the storage. If a new server
is installed in the BladeSystem c-Class enclosure, the storage volumes will be immediately
visible to that server.
