HP 3Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 36)

Advanced Settings task
The Multi-initiator mode setting controls whether more than one server device bay can be assigned
the same zone group.
To perform this task, select the active switch in the navigation tree, and click Advanced Settings.
Options for this task include:
•
Disabled—(Default) Used when only zoned SAS storage enclosures are connected to the
switch. When this option is selected, a zone group can be assigned to only one server device
bay.
•
Enabled—Used when shared SAS storage enclosures or tape autoloader/libraries are
connected to the switch. When this option is selected, a zone group can be assigned to
multiple server device bays.
NOTE:
•
In dual-domain switch configurations (two switches installed in the same interconnect bay row
of the HP BladeSystem c-Class enclosure), a change to this multi-initiator setting on the active
management switch is automatically propagated to the redundant (passive) switch.
•
When a tape autoloader or library is included in the solution, multi-initiator mode must be
enabled, so that multiple severs can be assigned the zone group that includes the tape device.
When using a tape device with zoned SAS storage enclosures, you must:
◦ Create a switch-port zone group for the port connected to the tape device.
◦ Assign that zone group to all server device bays that need access to the tape device.
◦ Create drive-bay zone groups for the disk drive bays in the storage enclosures.
◦ Assign each drive-bay zone group to the server device bay that needs access to those
disk drives. Use caution to not assign the same drive-bay zone group to more than one
server device bay.
