2C3

Explanation
The zFS Physical File System (PFS) encountered
an internal error. An internal reason code is displayed along with
the zFS 2C3 abend code. Each reason code is made up of 4 bytes; cccc
rrrr, where cccc is a halfword reason
code qualifier and rrrr is the halfword     reason code. The high-order
bytes of the reason codes returned contain a value that is used to
qualify the contents of the 2 low-order bytes. zFS reason code qualifiers
are found within the range X'EA00' to X'EAFF'. The
low-order bytes of the reason codes are found within the range X'0000' to X'FFFF'.

System action
The system issues an ABEND dump and then zFS might
attempt to stop and restart. Additional messages can be issued.

System programmer response
Search the problem reporting data
bases for a fix for the problem. If no fix exists, contact the IBM® Support Center and provide the
ABEND dump and the internal reason code.
If the automatic stop
and restart of zFS is unsuccessful, cancel the zFS address space and
then respond R to the BPXF032D WTOR to restart zFS.

The system this code issued on is taking a zFS
dump at the request of zFS running on another sysplex member.

The IOEAGFMT utility has attempted to obtain
storage and failed.
If possible, determine why the storage obtain
failed and correct the problem. Try to increase the region size for
the job and run it again. Ensure that a user exit does not cause the
job to fail to obtain storage.
0412
 zFS marked a zFS aggregate dead because of
an internal problem. zFS will attempt to dump on this system and on
each member of the sysplex (with the same abend reason code).
To recover the compatibility mode aggregate,
unmount it, run the zFS IOEAGSLV utility against it and then mount
it again.  See z/OS Distributed File Service zFS Administration for
information on IOEAGSLV.

Programmer response
None.
