HP 6G Virtual SAS Manager User Guide

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.
