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).
The following figure shows an example of a configuration in which SVPs are used as virtual command
devices. Because this configuration eliminates the need for connecting a command device to the pair
management server, you can install Device Manager Agent and P9000 RAID Manager on the
management server, allowing it to double as a pair management server.
Figure 9 Configuration using SVP as virtual command device
NOTE:
If the SVP is used as the virtual command device, there is no need to set up a Virtual Command Device
server or command device. However, command processing using the SVP takes significantly longer,
so HP recommends using a Virtual Command Device server for large-scale configurations.
