You can create an optional message queue, QSYSMSG, to hold specific severe system messages.
QSYSMSG holds only messages that require immediate action.
To create QSYSMSG, type CRTMSGQ QSYS/QSYSMSG TEXT ('OPTIONAL MSGQ TO RECEIVE SPECIFIC SYSTEM MESSAGES') at the command line and press Enter. The system then creates the message queue.
After you create the QSYSMSG message queue, your system stores specific system messages in it.
Example: CPF0907
Serious storage condition might exist. Press HELP.
