Recommended IBM and other maintenance to
be applied before running FDRPAS
SUPPORTED FDRPAS RELEASES:
Versions 5.4 level 17 of FDRPAS, and higher, are
supported. You should not run earlier releases of FDRPAS. V5.4/20 or above
is recommended.
REQUIRED IBM 2105 ESS MAINTENANCE:
If a source volume is in an IBM 2105 ESS (Shark)
with FICON channels, you should be at microcode level 1.5.2.114 or above
so that FDRPAS can properly identify the attached systems. This does not
affect target volumes but this microcode level is recommended even for
target systems.
REQUIRED AND RECOMMENDED IBM MAINTENANCE:
Please check this matrix against your operating
system level to see which IBM APARs should be applied (contact Innovation
if you are running an earlier level).

Brief IBM APAR descriptions follow (consult IBM for
complete APAR text). Note that some APARs may not be required in your
environment; see the text.
OW55469: this is a fix to Media Manager which was
implicated in a problem with FDRPAS and CA-OPSMVS (from Computer Associates).
If you are running CA-OPSMVS this fix is strongly recommended.
OW54976: you should apply the PTF to avoid SQA overlays
due to a problem in the IBM service IEEVARYD. You can avoid the problem
altogether by adding the undocumented operand "VARYON=NOAFTER" to all
SWAP and MONITOR statements on every system; however, this leads to a
rare case where concurrent copy and flashcopy do not work after the swap;
if this occurs, issue the console command
V uuuu,ONLINE,UNCOND
OW54317: this fix adds an interface which FDRPAS
can use to prevent Flashcopy and PPRC sessions from starting on a IBM
2105 Shark during a swap. If it is not installed, no errors will occur,
but FDRPAS will be unable to prevent such sessions from starting (they
may fail when the swap occurs).
OW53222/OW52127: you may want to apply the PTFs to
prevent accidentally IPLing from the old versions of SYSRES and IODF volumes
which have been swapped. These fixes are optional but recommended.
OW5263: if you swap to or from devices with PAV
(Parallel Access Volumes), You MUST apply the PTF for APAR OW52631 to
avoid a S0C4 abend in IOS after swapping
a non-PAV device to a PAV device or vice versa. The error may occur when
trying to use the non-PAV device after the swap.
OW52422: If you have applied the PTF for APAR OW51163
or are running z/OS 1.3, you should apply this PTF to avoid a S09A ABEND
with reason code CB01 in GRS after a swap (even if you use CA-MIM). This
abend will only occur if there is a RESERVE on the volume at the moment
of the actual swap; FDRPAS will not complete the swap until there are
no outstanding RESERVEs but it is possible for a RESERVE request to be
issued after FDRPAS checks. z/OS systems should also apply the PTF for
APAR
OW54570 to avoid a S0C4 abend in GRS after the S09A
abend. This problem is most likely on volumes with high RESERVE activity,
such as JES checkpoint volumes and other volumes with shared system-type
datasets such as catalogs, but it can affect any volume. In many cases,
the abend will affect the task issuing the RESERVE but will not harm other
tasks. If JES abends, you should be able to restart JES without affecting
running jobs.
OW51840: if you have applied the PTF for IBM APAR
OW48166 or one of the catalog level set PTFs UW81063/64/65, you MUST apply
this fix. This problem causes a loop in the catalog address space at the
end of a swap if you are NOT using ECS (Enhanced Catalog Sharing).
OW49783/OW51248: you may want to apply the PTF if
you plan to do dynamic I/O configuration after a swap (before the next
IPL).
OW49672: you MUST apply the PTF to avoid a hang when swapping a
volume containing a shared catalog. The APAR describes a catalog performance
problem, but it has resolved several hangs during swaps.
OW48166: if you are using ECS (Enhanced Catalog Sharing)
in a parallel sysplex, you should apply the PTF before swapping any volumes
containing catalogs. The fix will automatically remove a catalog from
ECS if it is on a volume that is swapped. You must also apply the PTF
for APAR OW51840. To determine if you are using ECS, issue this console
command on any system: F CATALOG,ECSHR(STATUS) if all catalogs displayed
have a status of "inactive", ECS is not in use. Circumvention: If you
have not applied the PTF, or you wish to avoid the catalog messages, IBM's
recommendation is to remove catalogs from ECS before you swap the volumes
on which those catalogs reside. Read the IBM APAR text for details.
OW46936: you may want to apply the PTF to avoid an
occasional ABEND0C4 during a swap. The ABEND0C4 is not harmful (the swap
will complete successfully) but it causes an unnecessary SVC DUMP. OW46459:
if you swap to or from devices with PAV (Parallel Access Volumes) and
are using WLM-managed dynamic aliases, you MUST apply the PTF to solve
problems with binding and unbinding aliases.
OW4610: you may want to apply the PTF to fix performance
problems on LLA-managed datasets after a swap. OW45683: you may want to
apply the PTF to fix performance problems after swapping to a device with
PAV (Parallel Access Volumes).
OW44548: If you have ever used FDR to convert DB2
or other linear VSAM clusters from 3380 disks to 3390 disks, and you are
now swapping those clusters to IBM 2105 Sharks, you should apply the PTF
to avoid I/O errors when re-loading or extending those clusters after
the swap. Circumvention: delete/define and reload the clusters before
or after the swap.
OW41858: you MUST apply the PTF before attempting
to swap to or from a device with PAV (Parallel Access Volumes). This PTF
adds a PAV interface routine that is invoked by FDRPAS.
OW31942: you MUST apply the PTF before attempting
to swap a volume from a device with a 3-digit device address to one with
a 4-digit address.
OW30926: if you plan to swap volumes containing system
couple datasets (CDS) it is recommended, but not required, that you apply
the PTF. This fix allows the coupling facility to better tolerate short
delays in I/O to the datasets, which may occurring during the swap. Without
the fix, there is a possibility that a coupling facility failure may occur.
See Section 320.02 of the FDRPAS manual for more information.
REQUIRED HDS (Hitachi Data Systems) MICROCODE
UPDATE:
Customers swapping to a HDS 9xxx Lightning disk subsystem
must insure that the microcode level is 01-13-19/00 or higher. Without
this microcode, FDRPAS monitor tasks may not recognize that a swap is
starting. UNSUBSCRIBING
