Configuring the switch – HP 3Gb SAS Switch for HP BladeSystem c-Class User Manual
Page 26
Configuring the switch
Key configuration tasks include:
1.
Enabling or disabling Multi-initiator mode.
2.
Creating zone groups:
• Switch-port zone groups: For shared SAS storage enclosures and tape libraries.
• Drive-bay zone groups: For zoned SAS storage enclosures.
3.
Assigning zone groups to servers.
4.
Capturing the configuration for safekeeping. HP strongly recommends this step, especially in
single-domain configurations. (Available only in the VSM CLI.)
NOTE:
For firmware versions earlier than 2.0.0.0, no configuration tasks are available.
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 page of the HP Manuals website
As shown in the following table, configuration (zoning) procedures are the same for shared SAS
