Command execution using in-band and out-of-band methods
The methods of executing commands provided by RAID Manager can be classified into the in-band
and out-of-band methods.
•
In-band method. This method transfers a command from the client or the server to the command
device of the storage system via Fibre and executes a RAID Manager operation instruction.
•
Out-of-band method. This method transfers a command from the client or the server to the
virtual command device in the SVP via LAN, assigning a RAID Manager operation instruction
to the storage system, and executes it.
When executing a command using the in-band and out-of-band methods, a command device or
a virtual command device is set in a configuration definition file as shown in the following figure.
The following figure shows a system configuration example and a setting example of a command
device and a virtual command device using the in-band and out-of-band methods.
