HP SAS BL manual Accessing the switch, Confirming the firmware version, Cabling the switch

IMPORTANT:

Do not connect SAS cables to external storage enclosures until you have accessed the switch and confirmed that the desired firmware version is installed on the switch (Accessing the switch).

IMPORTANT:

When two 3Gb SAS BL Switches are installed in the same row of an enclosure, make sure that they are running the same firmware version.

Accessing the switch

The switch is configured and managed through the Onboard Administrator (OA) and Virtual SAS Manager (VSM) applications.

To access VSM:

1.Access OA. NOTE:

The minimum OA version offering support for the 3Gb

SAS BL Switch is 2.40.

2.In the OA Systems and Devices tree, expand the Interconnect Bays, and select the 3Gb SAS BL Switch.

3.After selecting the SAS switch to manage, click Management Console and wait a few moments for the application to open. Then, log on to VSM using your OA username and password.

For details, see the HP Virtual SAS Manager user guide, available on the 3Gb SAS BL Switch manuals page http://www.hp.com/support/ manuals.

Confirming the firmware version

Firmware is pre-installed on each switch in the factory, but updated, alternative, or a preferred version may be available. The following types of firmware are available for the 3Gb SAS BL Switch; choose the firmware type that is best for your environment:

•Firmware versions less than 2.0.0.0—Single open zone support.

By default, all blade servers have access to all storage connected to the switch. This configuration is pre-configured and cannot be altered. To restrict access to the storage, use features included in your storage management software.

•Firmware versions 2.0.0.0 and higher—Multi-zone support.

By default, for servers to access storage, switch-port or drive-bay zone groups must be created. Zone groups provide user-defined isolation within the switch.

The installed firmware version is displayed in the VSM near the center of the HP Virtual SAS Manager banner. Access the VSM and make note of the installed firmware version on each 3Gb SAS BL Switch.

As needed, update firmware on the switches to the desired version. Firmware is installed using the VSM application. For details, see the HP Virtual SAS Manager user guide, available on the 3Gb SAS BL Switch manuals page http://www.hp.com/support/manuals.

Cabling the switch

After confirming the firmware version, connect SAS cables between the switch and the external SAS storage enclosures.

NOTE:

The 3Gb SAS BL Switch uses SAS cables with mini-SAS universal connectors. For a list of supported cables, see the 3Gb SAS Switch QuickSpecs.

For detailed cabling information, see the HP StorageWorks 3Gb SAS BL Switch user guide, available on the 3Gb SAS BL Switch manuals page http://www.hp.com/support/manuals.

Configuring the switch

•For firmware versions lower than 2.0.0.0, no configuration tasks are available.

•For firmware versions 2.0.0.0 or higher, key configuration steps in- clude:

•Entering switch parameters.

•Creating zone groups (switch-port based or drive-bay based).

•Assigning zone groups to servers.

The switch is configured using the Virtual SAS Manager (VSM) application. For more information on zoning and configuration tasks, see the HP Virtual SAS Manager user guide, available on the 3Gb SAS BL Switch manuals page http://www.hp.com/support/manuals.
