Sun Cluster 3.0 12/01 Software Installation Guide

How to Install VERITAS Volume Manager Software Only

This procedure uses the scvxinstall command to install VERITAS Volume Manager (VxVM) software only.

Note -

To create the rootdg disk group by encapsulating the root disk, do not use this procedure. Instead, go to "How to Install VERITAS Volume Manager Software and Encapsulate the Root Disk" to install VxVM software and encapsulate the root disk in one operation.

Perform this procedure on each node that you want to install with VxVM. You can install VxVM on all nodes of the cluster, or on only those nodes that are physically connected to the storage device(s) VxVM will manage.

Note -

Although the scvxinstall utility disables Dynamic Multipathing (DMP) at the start of installation processing, DMP is automatically re-enabled by VxVM version 3.1.1 or later when the VRTSvxvm package is installed. Earlier versions of VxVM must still run with DMP disabled.

  1. Ensure that all nodes in the cluster are running in cluster mode.

  2. Become superuser on a cluster node you intend to install with VxVM.

  3. Ensure that the node's /etc/name_to_major file does not already contain a vxio entry.

    If a vxio entry exists, remove it from the file. This entry might exist if VxVM was previously installed on other nodes of the cluster. The correct vxio entry is added automatically during installation of the VxVM software packages.

  4. Insert the VxVM CD-ROM into the CD-ROM drive on the node.

  5. Start scvxinstall in interactive installation mode.


    # scvxinstall -i

    The scvxinstall command automatically performs the following tasks.

    • Disables Dynamic Multipathing (DMP)

    • Installs the VRTSvxvm, VRTSvmdev, and VRTSvmman packages

    • Sets the vxio driver major number to 210

    See the scvxinstall(1M) man page for information.

  6. (Optional) Install the VxVM GUI.


    # pkgadd VRTSvmsa

    See your VxVM documentation for information about the VxVM GUI.

  7. Eject the CD-ROM.

  8. Install any VxVM patches.

    See the Sun Cluster 3.0 12/01 Release Notes for the location of patches and installation instructions.

  9. (Optional) If you prefer not to have VxVM man pages reside on the cluster node, remove the man page package.


    # pkgrm VRTSvmman

  10. Do you intend to install VxVM on another node?

  11. Are there one or more nodes that you do not intend to install with VxVM?

    Note -

    If you intend to enable the VxVM cluster feature, you must install VxVM on all nodes of the cluster. Go to Step 13.

  12. Modify the name_to_major file on each non-VxVM node.

    1. Become superuser on a node that you do not intend to install with VxVM.

    2. Edit the /etc/name_to_major file and add an entry to set the vxio major number to 210.


      # vi /etc/name_to_major
vxio 210

      Note -

      If you later install this node with VxVM, you must remove the vxio entry before you install VxVM.

    3. Initialize the vxio entry.


      # drvconfig -b -i vxio -m 210

      Note -

      The next time you reboot this node, you might see messages similar to the following. These messages are harmless and can be ignored. 


      /sbin/rcS: /usr/sbin/vxrecover: not found
/etc/rc2.d/S75MOUNTGFSYS: /usr/sbin/vxdctl: not found

    4. Repeat Step a through Step c on all other nodes that you do not intend to install with VxVM.

      When you finish, each node of the cluster should have the same vxio entry in its /etc/name_to_major file.

  13. Create a rootdg disk group.

    Go to "How to Create a rootdg Disk Group on a Non-Root Disk".
