Three commands are exclusively available via the API. These

are the Connect, Disconnect, and Multimount Media

associate commands.

Connect When a client issues a Connect command, the sending host

becomes a member of an Enterprise. An Enterprise is a group of

clients that communicate with the VolServ host computer.

When a client establishes an Enterprise connection, a unique

address is associated with it. This address is associated with a

parameter called the Enterprise ID. The Enterprise ID may then

be used as a target location for all media class callbacks. Refer

to the VSCMD_Connect command in the MSTM-V21-010 API

Programmer’s Guide and “Use Callbacks and Callback

Information” on page 3-23 for more information.

Disconnect The Disconnect command destroys a specific Enterprise that

was established with the Connect command. For more detailed

information about this command, refer to the

VSCMD_Disconnect command in the MSTM-V21-010 API

Programmer’s Guide.

Clients use the Multimount Media command to mount one

medium or more at one time. This frees the client from the

requirement of finding available drives, locking the drives,

finding applicable media, mounting the media on the locked

drives, and unlocking those drives.

All functionality of the mount command is retained in this

command. Refer to “Mount Media on a Drive” on page 4-18.
