Monitoring and managing storage systems using virtual
command devices
As an alternative to using P9000 RAID Manager command devices, you can also issue commands
to storage systems over the LAN connection using virtual command devices.
NOTE:
As of 7.1.0, Replication Manager only supports monitoring and managing copy pair configuration
definitions that use virtual command devices. You cannot set up such a configuration from within
Replication Manager.
This module includes the following topics:
• About virtual command devices
• Prerequisites for virtual command device configurations
• Setting up an SVP as a virtual command device
• Using a Virtual Command Device server
• Performing user authentication for replica operations
About virtual command devices
Command devices are used to send P9000 RAID Manager commands between the pair management
server and a storage system. Command devices use the FC link (known as an in-band connection).
Virtual command devices allow you to perform the same operations using the LAN (known as an
out-of-band connection). This configuration uses either the Service Processor (SVP) of the storage
system, or a dedicated P9000 RAID Manager server (known as a Virtual Command Device server).
