IMPORTANT: VERITAS CVM disk groups must be configured in a dedicated modular MNP package using the cvm_dg attribute. This modular MNP package must be configured to have a package dependency on the SG-CFS-pkg SMNP package.

Metrocluster SADTA does not support configuring Legacy style packages for managing VERITAS CVM disk groups.

Configuring the Storage Device using SLVM

Complete the following procedure to import volume groups on the nodes in the target disk site:

1.Define the appropriate volume groups on each host system in the target disk site.

#mkdir /dev/<vg_name>

#mknod /dev/<vg_name> /group c 64 0xn0000

where the name /dev/<vg_name> and the number nn are unique within the cluster.

2.Export the volume groups on the source disk site without removing the special device files.

#vgchange -a n <vg_name>

#vgexport -s -p -m <map_file_name> <vg_name>

Ensure that the map files are copied to all the nodes in the target disk site.

3.On the target disk site, import the VGs on all systems that will run the Serviceguard complex workload package.

# vgimport -s -m <map_file_name> <vg_name>

Configure the Identical Complex Workload Stack at the Recovery SIte

The complex workload must be packaged as Serviceguard MNP packages. This step creates the complex workload stack at the target disk site that will be configured to be managed by the Site Controller Package. For more information on configuring the complex workload stack, see the section “Configuring the Complex Workload Stack at the Source Disk Site” (page 351).

Halting the Complex Workload on the Recovery Site

You must halt the complex workload stack on the recovery site so that it can be restarted at the source disk site. Halt all the packages related to the complex workload using the cmhaltpkg command. When using CVM or CFS, run the vxdg deport command to deport the disk groups at the nodes in the replication target disk.

After halting the complex workload on the recovery site, you must re-synchronize the target disk from the source disk for the replication that was split using the procedures listed in the section “Preparing the Replicated Disk at the Target Disk Site” (page 352).

Configuring the Site Controller Package for the Complex Workload

The Site Controller Package and the Site Safety Latch for the disaster tolerant complex workload are the final components to be configured. Site controller package can be created using the Package Easy Deployment feature available in Serviceguard Manager version B.03.10. For more details, see Using Easy Deployment in Serviceguard and Metrocluster Environments on HP-UX 11i v3 available at http://www.hp.com/go/ hpux-serviceguard-docs —> HP Serviceguard.

This section describes the procedure to configure the Site Controller Package in a Metrocluster using command-line interface.
