CPU Architecture: VAX and Alpha
Version: v 6.2
Questions: 


We have 2 VAX 4705 and Storage Works 500 (DSSI connection)
in cluster with quorum disk.

We want to add an Alpha 4000 server to our cluster.
The system disk of the Alpha 4000 will be in the 
Storage Works 500.

Questions:

 1) Can we add the Alpha to the cluster ?
 2) From what we read, we won't be able to use 
    CLUSTER_CONFIG.COM.
 3) Is it going to work if we do the following :
    - Modify sysgen on the Alpha :
      - VAXCLUSTER = 2
      - QUORUM_DISK = $1$DUA0 ( VAX system disk )
      - INTERCONNECT = "CI"
      - QDSKVOTES = 1
      - MSCP_LOAD = 1
      - MSCP_SERVER_ALL = 1

    - Reboot 2 VAX and Alpha 

  Thank You

Yes. Be aware that there are restrictions around the number of host nodes permissible on a single DSSI, and around the number of host and storage nodes on a DSSI. Also check the particular OpenVMS version(s) for the level of support provided for the particular configuration. See the VMScluster Software Product Description (SPD) for this -- and more -- information. Also see the VMScluster manuals, and the OpenVMS Installation and Upgrade Manual. Background: you will be performing a `clean' installation of OpenVMS Alpha onto one of the disks present in the VMScluster, then configuring it as a VMScluster member. : 2) From what we read, we won't be able to use : CLUSTER_CONFIG.COM. This tool is platform-specific in most OpenVMS releases -- it can only add or modify VMScluster members of the same architecture.

You will also need to set SCSNODE and SCSSYSTEMID to non-default values. (The OpenVMS Alpha installation should ask you questions and then handle most of this configuration work for you.) : - Reboot 2 VAX and Alpha Correct. You may/will need to AUTOGEN all three, as well.
