07E

Explanation
A CONFIG or VARY command requested addition or
removal of hardware units from a configuration. To process the command,
the system checked the availability of device paths. While checking
the device paths, the system encountered an error. A hexadecimal reason
code in register 15 explains the error: Code
Explanation
04
The unit control block (UCB) address, passed to the device path
checking routine, did not point to the common segment of the UCB.
0C
An incorrect function code was passed to the device path checking
routine.
14
The system received a return code from a device path checking
routine indicating that an unrecoverable program or hardware error
occurred.

System action
The system ends the CONFIG or VARY command.

Operator response
Depending on the reason code, do the following: For reason code X'04' or X'0C', contact the
system programmer.
For reason code X'14', if you entered the VARY or CONFIG
command to bring a device online, try to vary the individual paths
to the device. If this is unsuccessful, contact hardware support.

System programmer response
Search problem reporting bases for
a fix for the problem. If no fix exists, contact the IBM® Support Center.
