Initialize Element Status Command (07h)

Initialize Element Status Command (07h)
The INITIALIZE ELEMENT STATUS command allows the media changer to
check all assigned element addresses for volume and any other status
relevant to that element address. The intent of this command is to enable
the Initiator to get a quick response from a subsequent
READ ELEMENT
STATUS
command. It may be useful to issue this command after a power
failure, if a volume has been changed by an operator, or if configurations
have been changed.
