Sun Cluster Data Service for Oracle Parallel Server/Real Application Clusters Guide for Solaris OS

Installing Storage Management Software With Sun Cluster Support for Oracle Parallel Server/Real Application Clusters

For Sun Cluster Support for Oracle Parallel Server/Real Application Clusters disks, use the following configurations.

How to Use VxVM

To use the VxVM software with Sun Cluster Support for Oracle Parallel Server/Real Application Clusters, perform the following tasks.

  1. (Optional) If you are using VxVM with the cluster feature, obtain a license for the Volume Manager cluster feature in addition to the basic VxVM license.

    See your VxVM documentation for more information about VxVM licensing requirements.

    Caution – Caution –

    Failure to correctly install the license for the Volume Manager cluster feature might cause a panic when you install Oracle Parallel Server/Real Application Clusters support. Before you install the Oracle Parallel Server/Real Application Clusters packages, run the vxlicense -p or vxlicrep command to ensure that you have installed a valid license for the Volume Manager cluster feature.

  2. Install and configure the VxVM software on the cluster nodes.

    See “Installing and Configuring VERITAS Volume Manager” in Sun Cluster Software Installation Guide for Solaris OS and the VxVM documentation for more information.

How to Use Hardware RAID Support

You can use Sun Cluster Support for Oracle Parallel Server/Real Application Clusters with hardware RAID support.

For example, you can use Sun StorEdgeTM A3500/A3500FC disk arrays with hardware RAID support and without VxVM software. To use this combination, configure raw device identities (/dev/did/rdsk*) on top of the disk arrays' logical unit numbers (LUNs). To set up the raw devices for Oracle Parallel Server/Real Application Clusters on a cluster that uses StorEdge A3500/A3500FC disk arrays with hardware RAID, perform the following steps.

  1. Create LUNs on the disk arrays.

    See the Sun Cluster hardware documentation for information about how to create LUNs.

  2. After you create the LUNs, run the format(1M) command to partition the disk arrays' LUNs into as many slices as you need.

    The following example lists output from the format command.


    # format

0. c0t2d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248>
   /sbus@3,0/SUNW,fas@3,8800000/sd@2,0
1. c0t3d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248>
   /sbus@3,0/SUNW,fas@3,8800000/sd@3,0
2. c1t5d0 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64>
   /pseudo/rdnexus@1/rdriver@5,0
3. c1t5d1 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64>
   /pseudo/rdnexus@1/rdriver@5,1
4. c2t5d0 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64>
   /pseudo/rdnexus@2/rdriver@5,0
5. c2t5d1 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64>
   /pseudo/rdnexus@2/rdriver@5,1
6. c3t4d2 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64>
   /pseudo/rdnexus@3/rdriver@4,2
    Note –

    To prevent a loss of disk partition information, do not start the partition at cylinder 0 for any disk slice that is used for raw data. The disk partition table is stored in cylinder 0 of the disk.

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

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


    # scdidadm -L

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

  4. Use the DID that the scdidadm output identifies to set up the raw devices.

    For example, the scdidadm output might identify that the raw DID that corresponds to the disk arrays' LUNs is d4. In this instance, use the /dev/did/rdsk/d4sN raw device, where N is the slice number.

How to Use the Cluster File System

  1. Create and mount the cluster file system.

    See “Configuring the Cluster” in Sun Cluster Software Installation Guide for Solaris OS for information about how to create and mount the cluster file system.

  2. When you add an entry to the /etc/vfstab file for the mount point, set UNIX file system (UFS) file-system-specific options for various types of Oracle files.

    See the following table.

    File Type 

    Options 

    Archived redo log files

    global, logging, forcedirectio

    Oracle application binary files, configuration files, alert files, and trace files

    global, logging
