IXC244E

Explanation
XCF could not open the data set indicated and will
attempt to continue to IPL the system without it.
b
In
the message text: dsname
The name of the couple data set.
volser
The DASD volume where the data set resides, if known.  (It may
be unknown when the master catalog is used to determine the volser,
but the data set has not been cataloged.)
text
One of the following: CONTINUING THE IPL USING SPECIFIED ALTERNATE AS PRIMARY
XCF is attempting to use the data set that was specified as the
Alternate in the COUPLExx parmlib member as the Primary Sysplex couple
data set, because the specified Primary could not be opened.
CONTINUING THE IPL WITHOUT AN ALTERNATE
XCF could not open the data set specified as the Alternate in
the COUPLExx parmlib member, and is continuing without it.

System action
XCF issues message IXC255I, giving the details
of the OPEN error which occurred for the specified data set and attempts
to continue the IPL without it.

Operator response
Contact the system programmer.

System programmer response
Determine why the open of the specified
data set failed.  If the name or volume serial of the data set is
incorrect in the COUPLExx parmlib member, correct it before the next
IPL.  If the data set name and volser are valid, but the data set
is on a volume that is inaccessible, format a new Sysplex couple data
set on another volume, update the COUPLExx parmlib member, and use
the SETXCF COUPLE,ACOUPLE command to add it to the current sysplex.
While
the sysplex is running with only one Sysplex couple data set, it is
exposed to errors on that device that could bring down the entire
sysplex.
