HP 6Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 29)

Helpful hints:
•
In dual-domain switch configurations (two switches installed in the same interconnect bay row
of the HP BladeSystem c-Class enclosure), a change to these settings on the active management
switch is automatically propagated to the passive switch.
•
When a P2000 G3 SAS MSA storage enclosure, tape autoloader, or library is included in
the solution with MDS600 or D2600/D2700 storage enclosures:
◦ Multi-initiator mode should be enabled, so that multiple severs can be assigned the zone
group that includes the P2000 G3 SAS MSA or tape device.
◦ Use caution when assigning drive bay zone groups, to prevent them from being assigned
to more than one server.
◦ Consider enabling port-splitting mode, so that multiple tape devices can be connected to
a single switch port.
