Multipathing
Multipathing is the process of providing a server more than one path to a storage system, so that in
the case of an emergency, the server will have continuous access to the storage system.
Multipathing can be done many ways. For example, you can provide redundant switches for a host
to access a storage system. Another example of multipathing is providing redundant paths from the
host to the switch. To determine if your multipathing software is supported, refer to the release notes.
Keep in mind the following:
• "SANtricity" Manager Utilities" must be installed on the host running RDAC for the management
server to obtain RDAC information.
• HDLM on Sun Solaris requires the storage array to be included in discovery in order to report
the correct information back to the bindings page. For more information about HDLM issues, see
"Troubleshooting HDLM."
• The software supports VERITAS Volume Manager without VxDMP, but VxDMP is required to do
multipathing.
