DFSMSrmm displays tape fetch and mount messages on both the operator console and the drive display panel. DFSMSrmm
modifies fetch and mount messages to provide information about shelf
location and scratch pools, when appropriate.
To list mount messages at the console, you can enter
"D R,KEY=MOUNT"
at the console.
Use MNTMSG commands in parmlib to identify the messages to be updated.
DFSMSrmm adds a pool prefix to the message for a non-specific mount
request and to the tape drive display unless you specify a pool name
using the VLPOOL commands with the NAME operand. In that case, DFSMSrmm
adds the pool name to the message. See z/OS DFSMSrmm Implementation and Customization Guide for information on the DFSMSrmm parmlib options.
For a specific mount request, DFSMSrmm adds the rack number to
the message text. The rack number identifies the specific shelf location
where the volume resides to help you locate the volume. This is particularly
useful in those cases where the rack number for a volume differs from
its volume serial number.
When the rack number or pool prefix or pool name is added to the
end of the mount message, the rack number or pool identifier is preceded
by eitherRACK= or POOL=. When the
rack number or pool identifier is added anywhere else in the message,
DFSMSrmm does not add the descriptive text.
These are some of the mount messages DFSMSrmm issues:
- EDG4013I M dev, volser, jobname, procname, stepname, rack, location, loc_bin, destination, dest_bin, loan_location
- EDG6627A M drive_number VOLUME(volser) RACK(rack_number) TO BE erased_or_labelled_or_verified
vol1_volser, label_type
- Mount the volume, write enabled. You do not need to reply to
this message. DFSMSrmm returns a null rack_number when the
volume is not defined to DFSMSrmm.
- If the volume cannot be mounted, reply 'S' to skip the volume.
- EDG6628A drive_number REPLY WITH RACK NUMBER
OR VOLUME SERIAL NUMBER FOR NL VOLUME
- The volume does not have a volume label, so DFSMSrmm cannot verify
that the correct volume is mounted. Check that the correct volume
is mounted. This message is issued during EDGINERS processing.
- Reply with the volume serial number or rack number.
- EDG6663D REPLY "R" TO RETRY OR "F" TO FAIL THE REQUEST, OR
"A" TO ACCEPT THE MOUNTED VOLUME
- During EDGINERS processing, DFSMSrmm detected an incorrect volume
serial number on a mounted volume. The EXEC statement PARM WRONGLABEL
parameter has been specified and DFSMSrmm prompts the operator to
reply. DFSMSrmm issues this message after issuing either message EDG6661E
or EDG6662E.
- Reply as described in Table 1.
Table 1. Operator
responses to message EDG6663D| To |
Reply |
And the result is |
|---|
| Accept the mounted volume |
A |
DFSMSrmm relabels the volume to the new volume serial number. |
| Fail the request |
F |
DFSMSrmm unloads the mounted volume and the request fails. |
| Retry to request |
R |
DFSMSrmm unloads the mounted volume and reissues the mount
request message EDG6627A. |
- IEF233A M dev,ser,[labtyp],jobname [,stepname] [,dsname], RACK=rackno | POOL=poolid
- This message is the normal mount message with addition of a rack
number or pool ID. Use the rack number or the pool ID to locate the
volume.
- The variables in the message text are:
- dev is the device number.
- ser is the volume serial number.
- labtyp is the type of label: SL for standard label, or
NL for no label or by-pass label.
- jobname is the name of the job.
- stepname is the name of the step.
- dsname is the data set name.
- rackno is the external tape label.
- poolid can be a pool prefix, which is the starting characters
of a rack number followed by asterisks (*) or a pool name, which
can be any one to eight character name your installation defines.
For example:
IEF233A M BE1,PRIVAT,SL,PRITCDSX,WRIT1,PRITCDS.POOL2.TEST - POOL=SCRATCH
shows the pool name added to the end of a message.
This message
shows the pool prefix updated in the existing message text:
IEF233A M BE1,A01***,SL,PRITCDSX,WRIT1,PRITCDS.POOL2.TEST
When DFSMSrmm uses the pool name rather than the pool prefix to
update the tape drive display for a mount request, if the pool name
is six characters or less, DFSMSrmm only updates the middle six characters
of the display.
The drive display of eight characters normally looks like this
for a mount of a standard label non-specific volume:
MPRIVATS
When DFSMSrmm updates the display with a six character pool prefix,
the display might look like this:
MA01***S
When DFSMSrmm updates the display with an eight character pool
name, the display might look like this:
BLUE-TAG
When DFSMSrmm updates the display with a pool name that is six
characters or less, the display might look like this:
MRED S
DFSMSrmm provides EDG019VM as a replacement for IFG019VM. This installation
exit is used to obtain the tape label of an NL tape mounted as a scratch
tape on a non-specific request from the operator.
- EDGV01D dev REPLY WITH RACK NUMBER FOR NL REQUEST — OR REPLY
"REJECT"
- DFSMSrmm issues this message to request the rack number for the
NL scratch tape to be mounted.
- Reply with the volume serial number for the scratch tape.
