Prerequisites for configuring a Management Server in Symmetrical DR environment

A virtual IP and a virtual host name are available for installing and using Veritas InfoScale Operations Manager in high availability and disaster recovery environment. This IP is used and configured in VCS for SFM_Services_IP and should not be shared with other applications.

Storage Foundation HA 5.x , or later, and VCS cluster are installed on the hosts that you want to designate as Node1 and Node2 in local site (Site A) and Node3 and Node4 in remote site (Site B). Also, Node1 in Site A and Node3 in Site B are considered as primary nodes. In case of HADR configuration using asymmetrical nodes, only one node is configured on the remote site (Node3 ).

Global Cluster Option (GCO) is enabled in VCS in Site A and Site B. For more information on enabling GCO, see Cluster Server Administrator's Guide.

Volume Replicator (VVR) is configured in Site A and Site B at VxVM level. For more information on configuring VVR, refer to the Veritas Volume Replicator Administrator's Guide.

All the nodes on which you want to configure Veritas InfoScale Operations Manager in the high availability environment must report synchronized Universal Time Clock (UTC/UC) time.

You must specify the database location. You can either use the default database location /var/opt/VTRSsfmcs/db or specify another location. If you specify the location other than the default database location, you must make sure that it is not part of the shared file system that is used for failover. Later, the Veritas InfoScale Operations Manager DR script moves the database to the shared file system.

If you do not use DNS Agent, you must add the host names to the /etc/hosts file.

The SFM_Services and the SFM_SStore base service groups that are created on Site A and Site B should have similar attributes and values, except for SFM_SStore_IP.

Use different virtual IP addresses for GCO IP and SFM_Services_IP.

The virtual host name that is used on all domains in Site A and Site B are the same.

The SFM_Services base service group must be configured as Global Service group between the two clusters.

SFM_SStore service is online on any of the nodes before you execute the disaster recovery script.

You need to create a Storage Foundation disk group, file system, and a volume for the data with identical names on all the nodes. Use VxVM and VxFS to create the file system and volume. The disk group, file system, and volume are used to configure the Veritas InfoScale Operations Manager database in high availability environment.
