After you have installed the Host Integration Tools kit version 3.1.1 or later, the utility EqlSetupUtil.exe is stored in the directory \EqualLogic\bin.

To configure the registry values, perform the following steps for each cluster host:

1.To configure the registry values, perform the following steps for each cluster host:

2.Go to the EqualLogic\bin directory. The default location is c:\Program Files\EqualLogic\bin.

3.For a Windows Server 2003 host, run EqlSetupUtil.exe -PRKey <PR key> . If it is a Windows Server 2008 host, run EqlSetupUtil.exe.

4.Reboot the system.

You can run EqlSetupUtil.exe to configure the following registry values:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk] "TimeOutValue"=dword:0000003c [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B- E325-11CE-BFC1-08002BE10318}\<Instance Number>\Parameters

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
