Enables or disables the MPE/iX movable volume facility. (Native Mode)

Syntax

VMOUNT { ON [,AUTO] OFF } [;ALL,]

Parameters

ON or ON,AUTO

Enables the movable volume facility so that all valid user MOUNT/VSRESERVE and operator LMOUNT/VSRESERVESYS requests are allowed. When ON is used without AUTO, the operator must reply to all MOUNT/VSRESERVE requests.

When ON,AUTO is used, MPE/iX attempts to satisfy user MOUNT/VSRESERVE and operator LMOUNT/VSRESERVESYS requests without operator intervention.

OFF

Requests to use the movable volume facility are rejected.

ALL

Prints all volume set mount-related console messages, including those not requiring operator intervention, on the console.

Operation Notes

If the movable volume facility is enabled when you issue a VMOUNT OFF command, users having reserved volume sets are unaffected; the command is satisfied when the last access is complete.

The MPE/iX naming convention for volume sets differs from that of MPE V/E for private volumes. Refer to the MOUNT, DISMOUNT, VSRESERVE, and VSRELEASE commands in this chapter.

Once the movable volume facility has been enabled, use the VSUSER command to determine which users have which volume sets reserved. Refer to the VSUSER command in this chapter.

The movable volume facility is enabled immediately following a system startup. (The setting is equivalent to VMOUNT ON,AUTO.) However, you still receive console messages concerning volume set requests.

The operator has the greatest interactive control over the use of volume sets by using VMOUNT ON;ALL. The command that least interrupts the operator when users are accessing volume sets is VMOUNT ON,AUTO.

Use

This command may be issued from a session, job, program, or in BREAK. Pressing Break has no effect on this command. It may be issued only from the console unless distributed to users with the ALLOW command.

Examples

To disable the movable volume facility so that no messages are sent to the console when users attempt to reserve volume sets (the default condition) enter:

 VMOUNT OFF

To disable the movable volume facility and still receive messages on the console when users attempt to reserve volume sets, enter:

 VMOUNT OFF;ALL
