Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA A.05.01

7. Create mount points for the complex workload data and set appropriate permissions.

# mkdir /cfs

# chmod 775 /cfs

# mkdir /cfs/<cvm_dg_name>

8. Create the Mount Point MNP package with a unique name in the cluster:

# cfsmntadm add <cvm dg name> <cvm_dg_vol_name> \

/cfs/<cvm_dg_name> <cfs_mount_point_pkg_name> all=rw \

where node1 and node2 are the nodes in the Source Disk Site.

Configuring the storage device for complex workload at the target disk site using SG

SMS CFS or CVM

To import CVM disk groups on the nodes in the target disk site and to create CFS disk group and

mount point MNP packages:

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 MNP packages for the disk groups with a unique name in

the cluster:

# cfsdgadm add <cvm_dg_name><cvm_dg_pkg_name> all=sw\

where node1 and node2 are the nodes at the target disk site.

3. Activate the complex workload disk groups in the CFS sub-cluster.

# cfsdgadm activate <cvm_dg_name>

4. Create the mount point directories for the complex workload cluster file systems.

# mkdir /cfs

# chmod 775 /cfs

# mkdir /cfs/<cvm_dg_name>

NOTE: Skip the following steps if you want to use the storage devices as raw CVM volumes.

5. Create the Mount Point MNP package with a unique name in the cluster:

# cfsmntadm add <cvm_dg_name><cvm_dg_vol_name>\

cvm_dg_name> </cfs/<cfs_mount_point_pkg_name> all=rw\

where node1 and node2 are the nodes at the target disk site.

6. Mount the cluster file systems in this CFS sub-cluster.

# cfsmount /cfs/<cvm_dg_name>

Migrating complex workloads using legacy SG SMS CVM/CFS packages to modular

packages with minimal downtime

To migrate all the legacy SG SMS CVM/CFS packages managed by a Site Controller package

to modular SG SMS CVM/CFS packages:

1. Halt the Site Controller that is running on the primary site in DETACH mode. When the Site

Controller package is halted in the DETACH mode, the Site Controller package goes down

without bringing down the complex workload packages. This is done by creating a file DETACH
