VCC Initialization and Parameter Message Log
 
This section of the VCC Run Status Report is produced during
standard VCC initialization.  VCCNTRL initialization error
messages, an echo of the run-time parameters, and parameter
scan error messages appear in this section.  See the VCCNTRL
and VCCPARSE message descriptions in Chapter 7, Return Codes
and Messages, for a list of these messages.
 
Figure 3-1 shows a typical Initialization and Parameter
Message Log.
 
 
VCC Processing Summary
 
This section of the VCC Run Status Report is produced by both
the standard and USS File System collection process just
prior to termination.
 
Figure 3-4 contains a typical example of the standard VCC
Processing Summary.  Figure 3-10 contains a typical example
of the Processing Summary for the HFS collection process.
The following describes the entries produced by both
collection processes.

                 system that ran VCC.
 
Previous Collection Date - The date and time of the last
                 successful VCC run.  The timestamp shown is
                 placed in the VCC record and is used by the
                 CA MICS Space Collector Option to compute
                 the duration to use for DASD space charging
                 in Accounting and Chargeback. If the VCC
                 control file is new or null at the time of
                 the VCC run, the word "UNKNOWN" is placed on
                 this line and the CA MICS Space Collector
                 Option computes a default duration based
                 on VCA parameter generation values.
 
Previous Process Time - The VCC processing start time and
                 Julian date for the previous VCC run.
 
                 Note:  If the last VCC run ended with
                 condition code zero although no records were
                 produced (which may or may not indicate an
                 error), this timestamp is updated.  The
                 timestamp shown is placed in the VCC record
                 and is used by the CA MICS Space Collector
                 Option to compute the duration to use for
                 DASD space charging in Accounting and
                 Chargeback.  If the VCC control file is new
                 or null at the time of the VCC run, the word
                 "UNKNOWN" is placed on this line and the CA
                 MICS Space Collector Option computes a
                 default duration based on VCA parameter
                 generation values.
 
Processing Start Time - The VCC processing start time and
                 Julian date.

                 purposes. The SMS level is shown in the
                 format vv.rr.mm.
 
SMS or DFP Level - The version, release, and modification
                 level of the Data Facility Product (DFP) or
                 System Managed Storage (SMS) for technical
                 support purposes. The SMS level is shown in
                 the format vv.rr.mm whereas the DFP level is
                 shown in the format v.r.m.l.

                 executed, displayed primarily to provide
                 information to Technical Support, if
                 needed.  For assistance, contact Technical
                 Support at http://ca.com/support.
 
Temporary Datasets Auto-Excluded - IF TEMPDSN=N is in effect
                 for the VCC run, the count shown indicates
                 the number of records VCC did not write to
                 its output data set (VCCDATA).
 
Total Online DASD Devices - The total number of DASD devices
                 in the I/O configuration of the system on
                 which VCC executed.  This is the number of
                 devices in the volume table built by VCC
                 initialization (see Chapter 5, Operation).
 
Uncataloged NonVSAM Datasets - If CATCHECK=Y is in effect for
                 the VCC run, the count of data sets that
                 were found to be either uncataloged or
                 invalidly cataloged is shown here.  When
                 CATCHECK=N is in effect, a question mark (?)
                 is shown to indicate that this statistic is
                 not known from this VCC scan.
 
USS File Systems Detected - The number of accessible file
                 systems detected by VCC.

                 file system that VCC found.
 
USS File System Directories - The number of directories
                 within a file system that VCC found.
 
VCC Records Bypassed - The number of records that were not
                 written due to a validity check on the
                 record length done by VCCWRITR.  In some
                 cases, a bad catalog cell causes a record of
                 excessive length to be constructed and
                 passed to VCCWRITR.  Rather than abend,
                 VCCWRITR will SNAP a portion of the record
                 (up to the maximum LRECL in the DCB) and
                 count the record as bypassed. Normally, the
                 count that appears here should be zero. If
                 non-zero, you can usually examine the SNAP
                 output and locate the data set name.  Other
                 facilities such as IDCAMS DIAGNOSE or PDF
                 can be used to determine if a data set or
                 catalog entry is invalid.
 
VCC Records Written - The number of records that VCC wrote.
                 These records are either written to SMF or
                 to a data set (user-selectable VCC option).
 
VSAM Catalog Records - The number of VSAM catalog records VCC
                 read during the catalog scan process.  This
                 number includes direct reads that were done
                 to get information from catalog extension
                 records.  Therefore, a catalog record can be
                 counted twice.
 
VSAM Catalogs Scanned - The number of standard VSAM catalogs
                 that were actually processed by VCC.
 
VTOC Dataset Records - The number of VTOC DSCBs that VCC read
                 during the VTOC scan process.
 
VTOC Scan Elapsed Time - The total elapsed time, in
                 hh:mm:ss.th format, it took VCC to process
                 the VTOCs on the DASD devices that were
                 selected to be scanned.
 
zSeries File Systems Detected - The number of zFS type data
                 sets that VCC detected during the VTOC scan
                 process.

                 the volume expressed as a percentage.
 
TOTAL VTOC TRKS - The size of the VTOC in tracks.
 
DSCB USE STATISTICS - A set of DSCB counts that are useful in
                 determining:
 
                   o  VTOC over-/underallocation
 
                   o  VTOC DSCB spread (how many DSCBs are
                      used in relation to the high used DSCB)

                 use (not binary zeros).
 
F1             - The number of Format 1 (data set identifier)
                 DSCBs in the VTOC.  The sum of this number
                 and the number of Format 8 DSCBs below
                 represent the number of data sets on the
                 DASD device.

F8             - The number of Format 8 (data set identifier)
                 DSCBs in the VTOC.  The sum of this number
                 and the number of Format 1 DSCBs above
                 represent the number of data sets on the
                 DASD device.  The Format 8 DSCB is used for
                 data sets that are eligible for placement in
                 cylinder-managed space on an Extended
                 Address Volume (EAV).
 
F9             - The number of Format 9 (data set attribute
                 information) DSCBs in the VTOC.  These DSCBs
                 occur only in conjunction with Format 8
                 DSCBs for data sets eligible for placement
                 in cylinder-managed space on an EAV.
 
HIGH USED      - The DSCB number in the VTOC of the last DSCB
                 in use.  This number is equivalent to the
                 number of VSAM READ macros issued by VCCVTOC
                 to read the VTOC.
 
 
The fields in the next set indicate specific attributes of
the DASD volume.  "Y" indicates that the attribute is
available or true.  "N" indicates that it is unavailable.
"?"  indicates unknown or unable to determine if the specific
attribute is available.
 
V I X   - Specifies whether a VTOC index exists on the DASD
          volume.
 
V V D   - Specifies whether an ICF VVDS exists on the DASD
          volume.
 
I C F   - Specifies whether an ICF BCS exists on the DASD
          volume.
 
S M S   - Indicates the DFSMS ownership status of this
          volume.  If an "I" appears in this field, the
          volume is in the process of being converted to
          SMS. The volume status is "INITIAL," indicating
          that some data sets are under SMS control.
 
S H R   - Indicates whether the DASD device is identified to
          the operating system as a device that is sharable
          between multiple systems.
 
E A V   - Indicates whether the DASD device is identified to
          the operating system as an Extended Address Volume
          (EAV).  An EAV volume is one that is configured
          with more than 65,520 cylinders. Cylinder-managed
          space exists and extended attribute DSCBs, format
          8 and 9 DSCBs, are permitted in the VTOC.
 
STORAGE GROUP  - If SMS is active and the volume is
                 SMS-managed, the storage group name is
                 shown.
 
PROCESS STATUS - Indicates error situations (if any) that
                 occurred during the scan of a volume.  This
                 report field will be present for all DASD
                 devices in this section of the VCC Run
                 Status Report.
 
                 The possible status values are:
 
                   Device Not Ready - VCC bypassed the
                        processing of this device because the
                        device was not ready at the time the
                        VTOC scan control table (VSCT) was
                        built.
 
                   DSN Residuals - One or more queue elements
                        for Format 1 DSCBs were found during
                        end of VTOC processing.  This
                        condition can only occur when an
                        error condition is encountered that
                        causes premature termination of scan
                        processing for a DASD volume.
 
                   EXT Not Found - A locate request for a
                        Format 3 DSCB on the EXT queue
                        resulted in a not-found condition.
                        This may be caused by an invalid
                        pointer in a Format 1 or 3 DSCB as
                        the result of an interrupted VTOC
                        update process.  The scan result may
                        or may not be in error depending on
                        the condition of the VTOC.
 
                   EXT Residuals - One or more residual
                        Format 3 DSCB extent records were
                        read, but the associated Format 1
                        DSCB records for them had not been
                        read by the VCC scan task.  This
                        condition will most likely occur when
                        processing DASD volumes with
                        extremely high activity if the
                        SERIALIZE=N option is in effect for
                        the VCC scanner.  This condition
                        might also occur as a result of a
                        system crash that occurred during an
                        update of the VTOC that has resulted
                        in a corrupted VTOC.
 
                   Incomplete Scan - A DASD volume being
                        processed encountered an error
                        condition.  One or more data records
                        have been written to the volume
                        record free extent segment, but not
                        all of the VTOC has been successfully
                        processed.
 
                   Lost Tracks - VCC VTOC processing of this
                        volume could not account for all of
                        the tracks on the volume.  The sum of
                        the allocated tracks, free tracks,
                        size of VTOC, and 1 for track 0 did
                        not equal the track capacity of the
                        volume.
 
                   Migration Level 1 - The DASD volume being
                        scanned was determined to be a DFHSM
                        migration level 1 storage volume.
                        Only the VTOC Volume Record will be
                        output for this volume, regardless of
                        the value of the DATAINFO= parameter.
 
                   Mount Attributes - VCC processing of this
                        device was bypassed because the
                        device was not mounted in a manner
                        that satisfied the requirements of
                        VCC (online and resident).
 
                   No VTOC Found - VCC was unable to process
                        a DASD volume because a valid pointer
                        to the VTOC did not exist in the UCB
                        for the device.
 
                   Processing Error - An error occurred
                        during the processing of the VTOC on
                        the DASD device.  The VTOC scan log
                        will contain a description of the
                        error.
 
                   PDSE Extended - The DASD volume was
                        explicitly specified on an
                        EXTENDEDPDSE parameter statement
                        causing extended attribute data for
                        the PDS/Es on the volume to be
                        collected.
 
                   PDSE No Extended - The DASD volume was
                        explicitly specified on an
                        NOEXTENDEDPDSE parameter statement
                        causing extended attribute data for
                        the PDS/Es on the volume NOT to be
                        collected.
 
                   Record Overflow - A volume contained more
                        free space extents than could be
                        placed into the data record. The VTOC
                        Volume Record free extent segment
                        will be incomplete.
 
                   Reserve Bypassed - A hardware RESERVE was
                        not done for this volume before it
                        was processed.  This was because
                        either the volume was specified in a
                        BYPASSRES parameter or because the
                        RESRETRY limit was exceeded and
                        RESFAILOK=Y was coded or defaulted.
 
                   Scan Abend Sxxx - An abend occurred during
                        scan processing of a DASD volume.
                        The Sxxx value indicates the abend
                        code returned by the system.  Scan
                        processing for the volume is
                        terminated and one of two actions is
                        taken. If the abend code is
                        determined to be recoverable, such as
                        an S213-04 from an invalid VTOC,
                        processing for the volume is
                        terminated, the environment is
                        cleaned up, and processing continues
                        with the next DASD volume.  If the
                        abend is determined to be
                        non-recoverable, processing for the
                        volume is terminated and the scan
                        subtask terminates after cleanup
                        processing.
 
                   Status Bypassed - The UCB status of the
                        DASD volume was found to contain
                        indicators that would prevent
                        successful scan processing of the
                        volume. If this condition persists
                        for three successive attempts, the
                        volume is permanently bypassed for
                        this processing execution.
 
                   Volume Excluded - VCC bypassed processing
                        of this device because the device
                        either was not INCLUDEd or was
                        specifically EXCLUDEd.
 
                   Volume Not Read - A VTOC was not processed
                        because of a critical error.
 
                   Volume Reserved - VCC could not process
                        this volume because it was reserved
                        by another user and VCC could not
                        reserve it.  You will receive this
                        message if the RESRETRY limit was
                        exceeded and RESFAILOK=N was coded.
 
                   VM Volume - Indicates a DASD volume that
                        has been formatted for use by a VM
                        operating system. These volumes
                        either have no VTOC or a non-standard
                        VTOC that cannot be processed by the
                        VCC scan task.

                        record.  The data/index cell
                        sets-of-fields information is not
                        accurate.
 
                   EXT S-O-F Error - An error occurred during
                        the processing of a VSAM catalog
                        record.  An extension record's
                        sets-of-fields information is not

                   Processing Error - Scan processing for a
                        BCS, VVDS. or VSAM catalog did not
                        complete. The interruption was
                        probably due to an abend condition.
                        Refer to the Catalog Scan Log for
                        additional information.
 
                   Read Error - An error occurred during the
                        execution of a VSAM GET macro.  Check
                        the Catalog Scan Log for the error
                        return and reason codes.  Refer to
                        the applicable IBM publication for

                   SMF Write Error - An error condition code
                        was returned from the SMFWTM service
                        while attempting to write the VCC
                        Catalog record to SMF.  Refer to the
                        Catalog Scan Log for additional
                        information.
 
                   Unknown Status - An error condition was
                        encountered while processing a BCS,
                        VVDS, or VSAM catalog.  The status
                        information returned was unknown to
                        the scan task. Refer to the Catalog
                        Scan Log for additional information.
