Creating a ServeRAID II Disk Resource on a ServeRAID II Server with MSCS

Creating a ServeRAID II Disk Resource on a ServeRAID II Server with MSCS

You can use a ServeRAID logical disk that has not been already designated as a cluster resource, or you can create a new array and logical disk on Server A, using the ServeRAID Configuration Program or the ServeRAID Administration and Monitoring Utility.
For more information about creating new arrays and logical disks, refer to the 'IBM ServeRAID Adapter Installation and User's Guide'.

Note: Be sure to assign a shared Merge ID to the new logical disk drive.

Before creating the ServeRAID II logical disk cluster resource, assign a sticky drive letter to the shared logical disk drive on both servers, using the Windows NT Disk Administrator Program, by following the next procedure.
(Use the IPSHAHTO.EXE utility to move the logical drive to the other server so an identical drive letter can be assigned.)

1.  On Server A, use the Windows NT Disk Administrator Program to assign a previously unused drive  letter to the new logical disk.
    For information on how to assign sticky drive letters, see the MSCS documentation.
2.  On Server B, use the ServeRAID Administration Monitoring Facility to scan for new devices.
3.  Run the IPSHAHTO.EXE utility on Server B to move the newly defined logical disk drive to Server B.
4.  Using the Windows NT Disk Administrator Program on Server B, assign the same sticky drive letter.

1.  On the system that owns the logical disk drive, run the Cluster Administration Utility program and  make this server the preferred owner of Cluster Group.
2.  Using the Cluster Administration Utility program, close the connection to the MSCS cluster and then reopen the connection.
    This ensures that your connection to the cluster is using the cluster server that owns the shared logical disk drive.
3.  To create the ServeRAID II disk resource in an existing group, ensure that the cluster server that owns  the shared logical disk drive is the owner of that group. If the cluster server is not the owner of the  group, use Move Group to make this cluster server the owner of the group where you will create the  ServeRAID II disk resource.
    Then, create the ServeRAID II disk resource.
4.  Bring the new ServeRAID II disk group online 
5.  If you you create a new ServeRAID II group, the cluster server that owns the shared logical disk drive  will be the owner of this group by default.
6.  Create a ServeRAID II disk resource as part of the new group.
7.  Bring the ServeRAID II disk group online.
