APAR Error Description / Circumvention

-----------------------------------------------
In a DB2 Mirror environment after a power down of the server
file system (SFS) the client file system (CFS) transformed to a
stand-alone file system (SAS) after the fail over of the
independent ASPs (IASP). The next switch back of the IASP(s),
fails with the following error messages:

MSGCPF9898 - 'IFS unmount failed for IASP xxxxx. Return code =
-1, Errno = 3572.'
MSGCPFB8E5 - 'Vary Configuration or Reclaim Storage detected a
problem.'
MSGCPF2640 - 'Vary command not processed.'

CORRECTION FOR APAR SE74016 :
-----------------------------
Locks preventing file system requests during a failover were not
appropriately released.
The PTF corrects the problem.

CIRCUMVENTION FOR APAR SE74016 :
--------------------------------
None.


Activation Instructions


This PTF contains objects that are activated only at IPL time.
Therefore, if this PTF is applied as an immediate PTF, you must perform
an IPL of the system to activate the PTF. Applying the PTF as an
immediate PTF will ensure that the PTF becomes active even after an
abnormal IPL where delayed PTFs are not applied.

If the PTF is applied as a delayed PTF, no further action is necessary.
