Sun Cluster 3.0 Release Notes Supplement

Data Services Installation and Configuration Guide

Additional documentation is needed when installing Sun Cluster HA for Oracle Parallel Server using the instructions in Chapter 8, "Installing and Configuring Sun Cluster HA for Oracle Parallel Server."

In the section, "How to Install Sun Cluster HA for Oracle Parallel Server Packages," it does not describe how to set up the LUNs if you are using RAID 5 rather than VERITAS Volume Manager.

This section should state that if you are using the Sun StorEdge A3500 disk array with hardware RAID, you use the RAID Manager (RM6) software to configure the Sun StorEdge A3500 LUNs. The LUNs can be configured as raw devices on top of the /dev/did/rdsk devices.

The section should also provide an example of how to configure the LUNs when using hardware RAID. This example should include the following steps:

  1. Create LUNs on the Sun StorEdge A3500 disk array.

    Refer to the information in Appendix A, Installing and Maintaining a Sun StorEdge A3500/A3500FC System to create the LUNs.

  2. After you create the LUNs, run the format(1M) command to partition the Sun StorEdge A3500 LUNs into as many slices as you need.

       /pseudo/rdnexus@3/rdriver@4,2


    Note -

    If you use slice 0, do not start the partition at cylinder 0.


  3. Run the scdidadm(1M) command to find the raw DID device that corresponds to the LUNs that you created in Step 1

    The following example lists output from the scdidadm -L command.


    1        phys-visa-1:/dev/rdsk/c0t2d0   /dev/did/rdsk/d1
    1        phys-visa-2:/dev/rdsk/c0t2d0   /dev/did/rdsk/d1
    2        phys-visa-1:/dev/rdsk/c0t3d0   /dev/did/rdsk/d2
    2        phys-visa-2:/dev/rdsk/c0t3d0   /dev/did/rdsk/d2
    3        phys-visa-2:/dev/rdsk/c4t4d0   /dev/did/rdsk/d3
    3        phys-visa-1:/dev/rdsk/c1t5d0   /dev/did/rdsk/d3
    4        phys-visa-2:/dev/rdsk/c3t5d0   /dev/did/rdsk/d4
    4        phys-visa-1:/dev/rdsk/c2t5d0   /dev/did/rdsk/d4
    5        phys-visa-2:/dev/rdsk/c4t4d1   /dev/did/rdsk/d5
    5        phys-visa-1:/dev/rdsk/c1t5d1   /dev/did/rdsk/d5
    6        phys-visa-2:/dev/rdsk/c3t5d1   /dev/did/rdsk/d6
    6        phys-visa-1:/dev/rdsk/c2t5d1   /dev/did/rdsk/d6

  4. Use the raw DID device that the scdidadm output identifies to configure OPS.

    For example, the scdidadm output might identify that the raw DID device that corresponds to the Sun StorEdge A3500 LUNs is d4. In this instance, use the /dev/did/rdsk/d4sx raw device, where x is the slice number, to configure OPS.
