Configuring the cluster volume manager

Cluster volume manager configuration tasks include:

• Specifying the CVM timeout interval
• Setting up naming scheme
• Setting up default disk group

Specifying the CVM timeout interval

By default, the Cluster Volume Manager (CVM) component is configured with a reconfiguration timeout value of 200 seconds. When you are prompted, accept the default, which is appropriate for most clusters.

 To specify the CVM timeout interval

• Enter the timeout interval for CVM:

  Enter Cluster Volume Manager cluster reconfiguration timeout (sec): (200)

  Refer to the Veritas Volume Manager documentation for more information on CVM.

Setting up naming scheme

Disks on HP-UX systems typically use device names such as /dev/rdsk/c#t#d# to identify disks on the system. It is possible to use the VxVM enclosure-based naming scheme, which allows disk arrays to be more readily recognizable. Dynamic Multipathing (DMP) is a prerequisite for enclosure-based naming schemes. Refer to the Veritas Volume Manager documentation for details on this scheme.

 To set up the naming scheme

1. If you want to set up the enclosure-based naming scheme, enter y.

   Do you want to set up the enclosure-based naming scheme? [y,n,q,?] (n)

2. Specify if you want to use the new naming scheme for all eligible systems.

   Do you want to use the enclosure-based naming scheme for all of the eligible systems? [y,n,q,?] (y)

Setting up default disk group

If applicable, set up the default disk group. Because some VxVM commands require that a disk group be specified, the installer enables you to register the name of a default VxVM disk group on each eligible node. Note that you can create the default disk group later.

1. If you want to set up a default disk group, enter y.

   Do you want to set up a system wide default disk group? [y,n,q,?] (y) y

   Which disk group? [<group>,list,q,?] xyz_dg

2. If you specified setting up a default disk group, review the setup output.

   Volume Manager default disk group setup and daemon startup
