The RY (Ready) command makes devices ready for system use if they were made inaccessible by an SV (Save) or SV (Save) command, or were locked by a program or by an SNL (Serial Number Lock) or a PG (Purge) command using the Lock (PGL) option.

The RY command puts modules into use.

Explanation

READY <device type> <unit number list>

Readies the device for use. The unit number can be an integer from 1 through 32767.

READY CPM <CPM list>

READY CPM <CPM list>:NOW

Readies the specified CPM for use by the system. The CPM numbers in the list can be integers from 0 through 15. If the NOW modifier is used, the CPM is readied without additional operator input.

READY IOP <number>

Readies the specified IOP for use for I/O operations. On completion, the IOP is marked READY in the PCD. The specified IOP remains READY through subsequent halt/loads until the user saves it using the SV (Save) command.

Examples

Example 1

This example readies a tape unit:

RY MT 113

   MT 113 WILL BE READY

Example 2

Considerations for Use

System Initialization Restrictions

A pack that is readied during system initialization is made available to the system only after initialization is completed. During initialization, if it is determined that an unavailable pack is needed, such as the CATALOG pack, you must halt/load the system again after you enter the RY PKnn command.
