Building Disaster Recovery Serviceguard Solutions Using Metrocluster with EMC SRDF

Configure the identical complex workload stack at the recovery site
The complex workload must be packaged as Serviceguard failover or 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 about configuring the complex workload
stack, see the section “Configuring the complex workload stack at the Source Disk Site” (page 42).
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 of 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, establish the SRDF logical replication
links.
# symrdf -g <device_group> establish -v
Configuring the Site Controller package for the complex workload
The Site Controller package and the Site Safety Latch for the disaster recovery complex workload
are the final components to be configured.
Configuring the Site Controller package using Serviceguard Manager
To configure a Site Controller package using Serviceguard Manager:
1. Access one of the node’s System Management Home Page at http://<nodename>:2301.
Log in using the root user credentials of the node.
2. Click Tools. If Serviceguard is installed, one of the widgets will have Serviceguard as an
option. Click the ‘Serviceguard Manager’ link within the widget.
3. On the Cluster’s Home Page, click the Configuration tab, and then select the Create a Site
Controller Package option.

4. If the product Metrocluster with EMC SRDF product is installed, you are prompted to select
the data replication type for the Site Controller package. Select the dts/mcsrdf module,
and then click Next.
