Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy for Linux B.12.00.00

6. Verify if the file system is present, and then unmount the file system.
# umount /<mountpoint_name>
7. Deport the disk group.
# vxdg deport <diskgroup_name>
Repeat steps 2 through 7 on all nodes in the cluster that require access to this disk group.
8. Login to the source disk site's 3PAR storage system. Reverse the direction of replication to
bring it back to its original direction.
cli% setrcopygroup reverse <rc_volume_group_name>
cli% startrcopygroup <rc_volume_group_name>
NOTE: It may be possible to skip the commands to stop and reverse the replication. However,
the import of disk group may take longer to complete.
Configuring Metrocluster Packages
A Metrocluster must be completed using Metrocluster 3PAR module dts/mc3parrc.
NOTE: The maximum number of Metrocluster packages that can be configured is 64. For more
information, see “Managing CLI connections to 3PAR array” (page 44).
Perform the following steps on a node in a Metrocluster to configure a modular package using the
Metrocluster 3PAR module on the command line:
1. Run the following command to create a modular package configuration file using the
Metrocluster with 3PAR Remote Copy for Linux module dts/mc3parrc.
# cmmakepkg –m dts/mc3parrc pkgName.config
In this command, dts/mc3parrc is the Metrocluster module that needs to be included to
create a Metrocluster package configuration file.
By default, the mc3parrc module includes only the Serviceguard volume group module.
If modules other than the Serviceguard modules need to be included, they must be explicitly
specified while creating the Metrocluster modular package configuration file.
The following example shows the package IP, the filesystem, and the monitor subnet module
included along with the mc3parrc module.
# cmmakepkg –m dts/mc3parrc –m sg/filesystem –m sg/monitor_subnet
\-m sg/package_ip pkgName.config
NOTE: Usually, Metrocluster is used with applications toolkits. Therefore, the application
toolkit module must be included when Metrocluster is used in conjunction with an application.
For example, when Metrocluster is used in conjunction with the HP Serviceguard Toolkit for
Oracle on Linux, then the toolkit module and other required modules must be included with
the Metrocluster with 3PAR Remote Copy for Linux module.
Run the following command:
# cmmakepkg –m dts/mc3parrc –m sg/filesystem -m sg/package_ip -m\
tkit/oracle/oracle pkgName.config
2. Edit the following attributes in the pkgName.config file.
