Command execution by the out-of-band method
In the RAID Manager before supporting P9500, a command can be executed only from the host
connected by the fibre channel directly. This is known as in-band operations. In the RAID Manager
supporting P9500, a command can be executed from any client PC connected to the storage
system via LAN, not just from connected hosts. This is known as out-of-band operations.
•
For in-band RAID Manager operations, the command device is used, which is a user-selected
and dedicated logical volume on the storage system that functions as the interface to the
storage system on the UNIX/PC host. The command device accepts read and write commands
that are executed by the storage system.
•
For out-of-band RAID Manager operations, a virtual command device is used. The virtual
command device is defined in the configuration definition file by an IP address on the SVP.
RAID Manager commands are issued from the client or the host server and transferred via
LAN to the virtual command device, and the requested operations are then performed by the
storage system.
The following figure illustrates in-band and out-of-band RAID Manager operations.
