Important tips

If needed, upgrade the P2000 G3 SAS MSA controllers to the latest firmware version before
connecting to the switch.
For dual-domain configurations, two controllers must be installed in each P2000 G3 SAS MSA
controller enclosure, and two I/O modules must be installed in each drive enclosure.
When cabling the P2000 G3 SAS MSA controller enclosure, P2000 drive enclosures, and
HP 6Gb SAS BL Switches, be sure to follow HP recommended best practices to provide a
highly available solution. For more information about cabling the devices, see the user
documents for the devices. Suggested references include the HP P2000 G3 MSA System
Cable Configuration Guide, HP P2000 G3 MSA System SAS User Guide, and HP 6Gb SAS
BL Switch User Guide. For sample BladeSystem solution cabling illustrations see

To connect P2000 drive enclosures to the P2000 G3 SAS MSA controller enclosure, a Mini-SAS
to SAS cable must be purchased. For more information, see the MSA2000 QuickSpecs or HP
P2000 G3 MSA System Cable Configuration Guide.
Maximum supported length of SAS cables is 4m.
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 P2000 G3 MSA System
◦
SMU Reference Guide.
For information about configuring storage in the CLI, see the HP P2000 G3 MSA System
◦
CLI Reference Guide.
(Optional but strongly recommended) Map each P2000 G3 storage 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 P71 1m/P712m
controllers that are contained in the same SAS zone can access the storage. If a new server
