Prerequisites for configuring a Management Server in DR environment

A Storage Foundation disk group, volume and a file system for the data is created. Use VxVM and VxFS to create the disk group, volume and a file system. The disk group, volume and a file system are used to configure the Veritas InfoScale Operations Manager database in high availability environment.

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

If you are using VVR for replication, ensure that Storage Foundation HA 7.3.1 or later, and VCS cluster are installed on the hosts that you want to designate as Node1 in local site (Site A) and Node2 in remote site (Site B).

If you are using VVR for replication, ensure that 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.

If you are using VVR for replication, ensure that Volume Replicator (VVR) should be configured in Site A and Site B at VxVM level. For more information on configuring VVR, see Volume Replicator Administrator's Guide.

Both the nodes on which you want to configure Veritas InfoScale Operations Manager in the disaster recovery 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/VRTSsfmcs/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.

Use different virtual IP addresses for GCO IP, SFM_Services_IP, and for the VVR rlinks.

The virtual host name corresponding to the virtual IP configured in SFM_Services_IP must be the same in Site A and Site B.

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.
