MNTMSG command operands

ID(nnn)

Specifies the starting position of the message identifier. Specify a value between 1 and 128.

Default: None. You must specify ID when you define a MNTMSG command in parmlib.

MSGID(nnnnnnnnnnnn)

Specifies message text 1 to 12 characters long. Normally the text is the message number, but it can include additional characters and blanks. You must enclose the MSGID value in quotation marks if you use blanks or special characters.

Default: None. You must specify MSGID when you define a MNTMSG command in parmlib.

RACK(nnn|999)

Specifies the position to insert the rack number, pool prefix, pool name, or storage group in the message. Specify a value between 1 and 128 to insert the value within the message text.

Use 999 if you want to add the value to the end of the message.

If the message has continuation lines, DFSMSrmm adds the required information to the end of the message regardless of the value specified with the RACK operand.

DFSMSrmm adds either RACK=rack_number or POOL=pool_value to the end of the message if there is enough space for the additional information. If you specify RACK(999), DFSMSrmm adds '- POOL=pool_value' if a pool name or storage group is substituted for a non-specific volume mount. For a rack number, DFSMSrmm writes nnnnnn. For a pool prefix, DFSMSrmm writes nnnnn*. For a pool name or storage group, DFSMSrmm writes nnnnnnnn.

If you specify RACK(999), DFSMSrmm adds - RACK=nnnnnn if a rack number is added:
```
IEF233A M 0480,999003,,J1400001,S0300 - RACK=T14103
```
If you specify RACK(999), DFSMSrmm adds - POOL=ppp* if a pool prefix is substituted for a non-specific volume mount:
```
IEF233A M 0480,PRIVAT,,J1400001,S0300 - POOL=AB****
```
If you specify RACK(999), DFSMSrmm adds - POOL=pool_value if a pool name is substituted for a non-specific volume mount.
```
IEF233A M 0480,PRIVAT,,J1400001,S0300 - POOL=SCRTCH00
```

If there is not enough space to add the information, DFSMSrmm overlays the end of the message text with the 6 to 8 character rack number or pool value preceded by a -.

To display the pool prefix in the message, you must specify the SYSID operand on the VLPOOL command as described in Defining pools: VLPOOL.

Default: None. You must specify RACK when you define a MNTMSG command in parmlib.

VOLUME(nnn)

Specifies the position of the volume serial number in the message. Specify a value between 1 and 128.

Default: None. You must specify VOLUME when you define a MNTMSG command in parmlib.
