IEC101A M dev,ser,jjj,sss [,dsname]
Explanation
M indicates that a volume is to be mounted on a
device:
- If the volume serial number is a 6-digit serial number, the volume with that serial number is to be mounted on the device.
- If the volume serial is SCRTCH, a scratch volume is to be mounted.
- If the volume serial number begins with a slash or L, the volume to be mounted is unlabeled; the number after the slash or L is an internal serial number assigned by the system to an unlabeled volume. If ser begins with L, the number after the L is of the form xxxyy, where xxx is the data set number and yy is the volume sequence number for the data set.
In the message text, labtyp and dsname appear only for tape volumes. The volume has the type of label specified by labtyp: SL for standard label, NSL for nonstandard label, or NL for no label; the density is as specified by den.
If a MONITOR DSNAME command is active, the data set contained on the volume is also specified in the message text.
In the message text:
- dev
- The device number of the specified device.
- ser
- The volume serial number.
- jjj
- The job name.
- sss
- The step name.
- dsname
- The data set name.
Operator response
If ser is SCRTCH, make sure that the file protection ring has been inserted in the volume.
Mount the volume on the device; then, ready the device.
