Setting Command Devices (In-Band Method)

CCI commands are issued by the CCI software to the RAID storage system command device.

The volume designated as the command device is used only by the storage system and is blocked from the user. The command device uses 32 MB, and the remaining volume space is reserved for CCI and its utilities.
