ANTX5130W

Explanation
XRC was unable to remove the indicated swap volume
from the indicated physical storage controller session ID. This may
cause impact to applications or prevent the volume from being used
for XRC or other copy services, depending on the status of the volume.
The swapdev is specified by a string with the following format: nnn
where nnn is the device number of the volume. 

An rc value of 4086 indicates
the primary volume is either not connected or not in the configuration.
A reas value
of 4086 indicates the swap volume is either not connected or not in
the configuration.

System action
XRC functions are active. The XDELPAIR command
succeeds and the primary and secondary volume pair is removed from
the XRC session, but the swap XRC session(s) remains activated for
the swap volume.

System programmer response
Since the swap sessions will not be
cleaned up automatically, the F ANTAS000,TERMSESS command(s) will
need to be   issued for each of the affected sessions.  In addition,
if this warning was issued as a result of an XEND after an   unsuccessful
transition from mode normal to mode HYPER-PPRC, all of the sessions
in an ER group (as observed with an   F ANTAS000,LISTSESS command)
may need to be manually terminated on the swap device even though
only a subset of   swap utilities were added.
