Requirements for Unified Manager in a failover clustering environment
Before installing Unified Manager in a failover clustering environment, you must ensure that the cluster nodes are properly configured to support Unified Manager.
You must ensure that the failover cluster configuration meets the following requirements:
-
Both the cluster nodes must be running the same version of Microsoft Windows Server.
-
The same version of Unified Manager must be installed using the same path on both the cluster nodes.
-
Failover clustering must be installed and enabled on both the nodes.
See Microsoft documentation for instructions.
-
You must have used Fibre Channel switched fabric or iSCSI-based storage for creating shared data disk as the storage back-end.
-
Optional: Using SnapDrive for Windows, a shared location must be created that is accessible to both the nodes in the high-availability setup.
See the SnapDrive for Windows Installation Guide for information about installing and creating a shared location.
You can also manage LUNs using the storage system command-line interface. See the SnapDrive for Windows compatibility matrix for more information.
-
You must have the Perl installed with
XML::LibXML
andFile::chdir
modules for scripts to work. -
There must be only two nodes in the cluster setup.
-
The “node and disk majority” quorum type must be used for failover clustering.
-
You must have configured a shared IP address with a corresponding FQDN to be used as the cluster global IP address to access Unified Manager.
-
The password for Unified Manager maintenance user on both the nodes must be same.
-
You must have used only IPv4 IP address.
