Universal Volume Manager Operations
Universal Volume Manager enables you to execute the following operations.
• Preparing to use external volumes
You can map external volumes, set port attributes, and set cross-
subsystem paths.
• Preparing to manipulate the power supply of the storage systems
You must follow specific procedures if you want to manipulate the power
supply of the storage systems when external volumes are used. To turn on
or off the power supply of the external storage system after starting to use
the external volumes, you need to execute the commands of Universal
Volume Manager.
• Setting up and removing the cross-subsystem paths
When you set up or remove the path (cable) connecting the storage
systems, you need to use the Universal Volume Manager to make settings
on the path.
• Referring to the status of external volumes
You can refer to the status and the configuration of external volumes.
• Stopping the use of external volumes
You can cancel mapping of external volumes.
• Mapping external volumes by using spreadsheets
Universal Volume Manager supports the Configuration File Loader
spreadsheets. Spreadsheets allow you to configure the mapping of multiple
external volumes at one time, which is efficient when mapping a large
number of volumes.
• Setting the remote command device
By using the remote command device, you can manipulate volumes in the
external storage system from the Command Control Interface on host
computers.
