Description

The mkbdsp command assigns a backing device to a virtual SCSI server adapter. If the -sp flag is not specified the default storage pool will be used. The user has the option of selecting a specific backing device, using the -bd flag, or simply specifying the amount of storage required. Only logical volume backing device can be specified with the -bd flag. If the storage size is given, the mkvdev command will create a backing device of at least the specified size and assign it as the backing device. Size can be given in megabytes (###M/n), gigabytes (###G/g), or physical partitions (###). The user also has the option of assigning the name for the newly created backing device using the -bd flag in combination with the size parameter..
