HP Serviceguard Metrocluster # cmapplyconf -v -P cvmdgpkgname.conf, # vgchange -a n /dev/vgname

1.Create a package configuration file using the following modules:

# cmmakepkg -m sg/multi_node -m sg/dependency -m\ sg/resource -m sg/volume_group <cvm_dg_pkg_name>.conf

2.Edit the configuration file and specify values for the following attributes:

package_name <cvm_dg_pkg_name> package_type multi_node cvm_dg <cvm_dg_name>

cvm_activation_cmd "vxdg -g \${DiskGroup}set activation=sharedwrite"

3.Specify the nodes in the primary cluster using the node_name attribute. node_name <node1>

node_name <node2>

In this command, <node1> and <node2> are nodes in the primary cluster.

4.Specify the Serviceguard dependency. dependency_name SG-CFS-pkg_dep dependency_condition SG-CFS-pkg=up dependency_location same_node

5.Apply the newly created package configuration.

# cmapplyconf -v -P <cvm_dg_pkg_name>.conf

Configuring the storage device using SLVM

To create volume groups on the primary cluster:

1.Define the appropriate volume groups on every host system in the primary cluster.

#mkdir /dev/<vg_name>

#mknod /dev/<vg_name>/group c 64 0xnn0000

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

2.Create the volume group on the source volumes.

#pvcreate -f /dev/rdsk/cxtydz

#vgcreate /dev/<vg_name> /dev/dsk/cxtydz

3.Create the logical volume for the volume group.

#lvcreate -L XXXX /dev/<vg_name>

In this command, XXXX indicates the size in MB.

4.Export the volume groups on the primary system without removing the special device files.

#vgchange -a n <vg_name>

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

Ensure that you copy the mapfiles to all host systems.

5.On the nodes in the primary cluster, import the volume group.

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

6.On every node, ensure that the volume group to be shared is currently inactive on all the nodes.

#vgchange -a n /dev/<vg_name>

7.On the configuration node, make the volume group shareable by members of the primary cluster in the cluster.

#vgchange -S y -c y /dev/<vg_name>
