IMPORTANT:  
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).  
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.  
Cabling the switch  
After confirming the firmware version, connect SAS cables between the  
switch and the external SAS storage enclosures.  
To access VSM:  
NOTE:  
1. Access OA.  
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.  
NOTE:  
The minimum OA version offering support for the 3Gb  
SAS BL Switch is 2.40.  
For detailed cabling information, see the HP StorageWorks 3Gb SAS  
BL Switch user guide, available on the 3Gb SAS BL Switch manuals  
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.  
Configuring the switch  
For firmware versions lower than 2.0.0.0, no configuration tasks are  
available.  
For details, see the HP Virtual SAS Manager user guide, available on  
the 3Gb SAS BL Switch manuals page http://www.hp.com/support/  
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.  
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:  
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.  
Firmware versions less than 2.0.0.0—Single open zone support.  
nl  
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.  
Regulatory notice  
For details, see the HP BladeSystem enclosure setup and installation  
guide.  
Firmware versions 2.0.0.0 and higher—Multi-zone support.  
nl  
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.  
Additional information  
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
