HP StorageWorks Hardware Providers for VDS/VSS installation guide (T1634-96096, April 2010)

5. For VSS, add primary and SVOL (secondary) LUNs to the primary and SVOL host groups, respect-
ively. The primary and secondary LUNs must be the same emulation type (for example OPEN-3,
OPEN-9) and the same size in GB. You must create at least an equal number of primary and
secondary LUNs so that there are enough secondary LUNs to hold the primary LUN copies. Some
applications require twice as many or more secondary LUNs as primary LUNs. Windows limits
LUNs to the range of 00 to 0xFE; do not to use a LUN number above 0xFE.
6. For VSS only, configure the disk array Fibre Channel port connected to the VDS/VSS server(s)
as follows:
ProvidesConnection parameter
Fabric para-
meter
NL-port (private arbitrated loop)FC-ALOFF
NL-port (public loop) for loop connection to a switchFC-ALON
N-port (fabric port) for connection to a switchPOINT-TO-POINTON
Not supportedPOINT-TO-POINTOFF
Configuring LUNs
Add primary, SVOL, and Shadow host groups.
Preparing the disk array for VSS
The following configuration step is required only if you will use VSS to make volume shadow copies.
If you are only using VDS and will not use VSS, skip this step.
