How to Create a Physical Disk Resource with Cluster.exe

When you attempt to add a physical disk resource to a cluster using Cluster Administrator, you may run into an issue where you might find that the �Disk Parameters� page does not display the entry for your newly added disk. This usually occurs because of the way you added the disk to the shared SCSI bus and the way the clusdisk driver reads the storage devices. You can follow the procedure outlined here for manually adding the�device using cluster.exe command.
�
Details
�
Open a command prompt and issue the following commands:
�
c:\>Cluster . res "Disk X:" /create /group:"Disk Group 1" /type:"physical disk"
- This command creates a physical disk resource named Disk X: in a group named Disk Group 1.�
�
c:\>Cluster . res "Disk X:" /priv Drive="X:"
- This command associates the physical disk with disk using the X: drive letter. If you are using mount�points, you must specify the Volume information for the mount point. For example: Drive=Volume{01018699-83c0-11da-a1a7-000bdb90efcd}�
�
c:\>Cluster . res "Disk X:" /On
- This command brings the newly created physical disk resource online.
�
Additional Information
�
The 'Drive=' parameter is a hidden disk resource property that resolves the disk signature for the specified mount point. If you look at the private properties of a cluster disk resource, it�only displays the signature value. You can also use a disk signature value when creating the disk resource instead of specifying the Drive value.�There are many ways to find this value such as using�dumpcfg.exe utility or diskpart.exe. Record the disk signature for this device and then use a command such as:
�
c:\>Cluster . res "Disk X:" /priv signature=0xEA0D9534
- This command associates the physical disk with signature EA0D9534 to the Disk X: resource. This command was done using the hexadecimal format of the disk signature but can also be done using the decimal equivalent signature.

When you want to add a new physical disk resource to a cluster, you may find it easier to create the resource using the Cluster Administrator. For additional information, see the article�below about the proper way to add a disk to a cluster using Cluster Administrator:
