Additionally, each Windows Server 2003 cluster host is required to have the following registry values:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msiscdsm \PersistentReservation] "UsePersistentReservation"=dword:00000001 "PersistentReservationKey"=hex:<PR key>

NOTE: <PR Key> is a unique 8-byte binary value that is composed of a 6-byte part that is specific to the cluster and a 2-byte part that is specific to the node. For example if you have a three node cluster you can assign 0xaabbccccbbaa as the cluster specific part. The nodes can then have the following PR keys:

–Node 1: 0xaabbccccbbaa0001

–Node 2: 0xaabbccccbbaa0002

–Node 3: 0xaabbccccbbaa0003
