where node3 and node4 are the nodes at the target disk site.
Do not configure any mount specific attributes like cfs_mount_point, cfs_mount_options
if SG SMS CVM is configured as raw volumes.
4. Check the package configuration file.
# cmcheckconf -P cfspkg1.ascii
5. Apply the package configuration file.
# cmapplyconf -P cfspkg1.ascii
6. Run the package:
# cmrunpkg <siteB_cfs_pkg_name>
Configuring the storage device using VERITAS CVM
To import CVM disk groups on the nodes in the target disk site and to create Serviceguard CVM
disk group package as follows:
1. From the CVM master node at the target disk site, import the disk groups used by the complex
workload.
# vxdg -stfC import <cvm_dg_name>
2. Create Serviceguard disk group modular MNP packages for the CVM disk group.
IMPORTANT: Configure VERITAS CVM disk groups in a dedicated modular multi-node package
using the cvm_dg attribute. This modular MNP package must be configured to have a package
dependency on the SG-CFS-pkg system multi-node package.
Metrocluster SADTA does not support configuring Legacy style packages for managing VERITAS
CVM disk groups.
Configuring the storage device using SLVM
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.
NOTE: If you are using the March 2008 version or later of HP-UX 11i v3, skip step 1;
vgimport (1m) will create the device file.
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>
