The objectives of FYI are to share
with you the answers to common questions that users ask, to
bring you up-to-date on our products' latest capabilities,
to differentiate our products' capabilities versus the competition
and to provide you with hints and recommendations.
FOCUS ON:
FDR full-volume high-speed backups may be used to back up S/390 Linux volumes
in CDL (compatible) format, but only full-volume recoveries are possible from
these backups. You cannot restore individual Linux files from full-volume backups.
Since Linux uses 'lazy writes', you must 'harden' the Linux data to disk before
dumping it with FDR by unmounting the Linux file system or shutting down Linux.
VM volumes containing Linux minidisks can also be backed up with FDR. Although
it is possible to restore individual Linux minidisks, you still cannot restore
individual Linux files from these backups.
FDR full-volume backups and FDRDSF data set backups may be used for high-speed
backups of the HFS and zFS data sets used by OS/390 UNIX System Services (USS).
You can restore entire individual HFS and zFS data sets from these backups but
you cannot restore individual USS files from these backups. When backing up HFS
data sets, you should also 'harden' the data by unmounting the file systems or
using the FDR parameter HFS=QUIESCE to quiesce the file systems during backup.
So, these FDR backups can be used for high-speed restores for disaster recovery,
and for local recovery of entire volumes, or file systems, but they are not appropriate
for recovery of individual files which have become lost or corrupted.
Innovation offers FDR/UPSTREAM for S/390 Linux and OS/390 UNIX to address this
need. FDR/UPSTREAM can back up Linux S/390 and OS/390 UNIX files to OS/390 mainframe
disk or tape without requiring an unmount or shut down. FDR/UPSTREAM can restore
individual files or groups of files on command.
One of the key NEW features of FDR/UPSTREAM S/390 Linux is:
A powerful and unique addition to the FDR/UPSTREAM S/390 Linux support is the
S/390 Linux Rescuer, the industry's first and only complete backup and restore
solution with disaster recovery for S/390 Linux. The S/390 Linux Rescuer is a
stand alone system recovery facility for SuSE S/390 Linux systems.
The S/390 Linux Rescuer allows administrators to completely restore a system
from data that is saved in FDR/UPSTREAM without separate system backups. S/390
Linux Rescuer is completely integrated into FDR/UPSTREAM.
In addition to the S/390 Linux Rescuer, UPSTREAM provides:
- Logical file backup for network attached Linux on the Desktop, Linux
on Intel Servers as well as Linux for S/390.
- Online Database agents for Oracle and DB2 for S/390 Linux.
All FDR programs have been updated to support 'large disks' (up to 32760 cylinders
in size). Most reports will identify disks larger than a 3390-9 as a '3390-27'
(for 27GB capacity).
The FASTCPK recovery log has been enhanced to handle a larger number of relocated
tracks, enabling it to support large disks and 3390-9 disks without special processing
or multiple executions.
In FDREPORT, 'ENABLE=LARGEDISK' is required to support devices larger than a
3390-9.
- FDREPORT can now access and report on offline disk volumes. Offline
volumes may be used with point-in-time backups (such as FDRINSTANT)
or with other special volume replication functions (PPRC, SRDF, BCVs,
ShadowImage, FlashCopy, SnapShot, etc).
- The new option FASTPATH (ENABLE=FASTPATH) significantly reduces the
overhead of allocating and opening disk volumes, improving FDREPORT
efficiency when processing large numbers of disk volumes. FASTPATH
can reduce FDREPORT execution time from 25% to 75% when processing
many disk volumes, depending on the type of report you have requested.
FASTPATH is required when reporting on offline volumes.
FDRDSF, FDRCOPY and FDRABR have been enhanced when restoring or copying multi-volume
VSAM clusters. FDR will now continue searching the available output volumes (NVOL=)
for a volume with sufficient space to allocate each piece of the cluster, for
SMS as well as non-SMS. As long as volumes are available in the NVOL list or
SMS storage group with sufficient free space (and size) to handle the extents
of the cluster, the restore/copy will be successful.
The Archive Control File (ACF) can now contain records for up to 5,701,632 data
sets or VSAM components.
FDRREORG has been updated to handle all currently supported types of IAM and
VSAM data sets. The CONVERTINDEX operand can be used to convert VSAM files which
were originally allocated with IMBED or REPLICATE to NOIMBED and NOREPLICATE,
since IBM no longer recommends those options.
FDRINSTANT for EMC now supports Concurrent BCVs, a new feature in TimeFinder
which allows 2 BCVs to be connected to the same standard volume at once. FDRINSTANT
can SPLIT and RE-ESTABLISH either BCV.
FDRINSTANT now uses EMC Instant Split as a default. FDRINSTANT customers running
V5.4 Level 20, 21 or 22 should request zap P-54.2034 to improve the performance
of Instant Split. Zap is automatically applied on V5.4 L23 or higher.
You have the option of sending e-mail messages when an FDR, FDRDSF, FDRCOPY or
FDRABR operation is unsuccessful (and if you like, for successful operations
as well). An optional FDREMAIL DD statement in an FDR step will invoke the facility;
it points to control statements defining the message and its recipients. A mail
server that supports SMTP (Simple Mail Transport Protocol) is required. Messages
can also be sent to alphanumeric pagers and cell phones.
The Concepts and Facilities Guides are a detailed overview of how
a particular INNOVATION component works, with helpful hints.

WHITE PAPER
For important technical information about FDRINSTANT, ask for a copy of our latest
White Paper on Corporate Data Protection with a Special Focus on DB2.
- 3590-H (triple density) tape drives are supported.
- VTS AND COPYCROSS SUPPORT -- Tape volumes in an IBM VTS (virtual
tape server) and EMC's CopyCross product will now be identified as
device type VIRTUAL. The capacity and used percentage for an IBM VTS
virtual tape volume will be reported.
- File statistics (bytes, blocks, etc.) will be printed for each file
copied.
- FDRABR backup tape files and DFSMShsm backup and migration tape files
will be automatically excluded by matching the tape data set name against
various masks.
- Data sets can be selected based on their size in megabytes (MB).
- Copy the 'volume assigned' date/time for RMM.
- Copy the 'creating program name' with CA-1.
- Selection can be limited to data sets cataloged to EMC CopyCross
virtual tape volumes.
- In a simulation run, the capacity of the output tapes that will be
used can be specified. The report will display the estimated number
of volumes of that capacity required to hold the data selected by the
simulation.
- Single System Record Level Sharing (RLS)-No programming changes.
- Full Journaling and Recovery Tools when files are used under IAM
RLS.
- Hardware Compression Support.
- Improved PAV Support and Backup While Open Support.
- IAM files can now be defined as DFSMS extended format sequential
datasets.
- 3390-27 (27 GB DASD) support allows IAM to use all available space
on the large volume.
- IAM Support for RRDS files will be available at no additional charge
to all IAM users who are licensed for IAM/AIX.
- UPSTREAM/SOS local backup volumes supports bi-directional operations
for backups AND restores and for file transfer operations, providing
the high-speed data transfer and reduced network overhead of UPSTREAM/SOS.
- UPSTREAM features logical file level support for S/390 Linux as well
as new non-disruptive online database agents for Oracle and DB2 UDB.
These agents provide non-disruptive online support for backups of the
databases without having to take the databases offline. An additional
benefit is the ability to perform incremental processing.
- The S/390 Linux Rescuer is a stand alone system recovery facility
for SuSE S/390 Linux systems. The S/390 Linux Rescuer allows administrators
to completely restore a system from data that is saved in FDR/UPSTREAM
without separate system backups.
- The UPSTREAM Rescuer also supports Sun Solaris.
- FDR/UPSTREAM provides sophisticated cluster support for Windows NT,
Windows 2000 and NetWare 6 cluster servers.
- UPSTREAM provides support for cluster specific information--for example,
the Cluster Quorum database for Windows 2000. Backups started on a
cluster-aware UPSTREAM system can be automatically restarted when a
cluster server failover occurs--providing the highest possible availability
for your backup services.
- The new UPSTREAM DB2 (UDB) agent now supports multiple, simultaneous
backup and restore operations resulting in the fastest possible operations.
- UPSTREAM now has the ability to send e-mail and SNMP Trap notifications.
By configuring your backups and restores to send notifications of specific
events, you can add another valuable management tool to your data management
capabilities.
- JES3-Managed Disk Volumes can now be Swapped with FDRPAS.
In FDREPORT V5.4, it is possible to obtain a report that contains only one line
per data set, even if the data set extends across multiple volumes and/or is
a VSAM cluster with multiple components. Fields that are additive, such as extents,
bytes, and tracks, will show the total for all parts of the component, cluster,
or non-VSAM data set. Percentages will be calculated based on these totals. Other
fields, such as record length and key position, will be taken from the first
volume. In a report line for a cluster, fields that are not totaled will be taken
from the data component.
This new feature is called RECORDSUMMARY, because each record (report line) may
be a summary of multiple volumes and/or components. This is different from the
summaries controlled by the SUMMARY command and the SUM= operand, which are produced
at control breaks between sets of report lines. RECORDSUMMARY can be requested
if you are processing with any of these three data types: CATARCH, CATVTOC, or
EXTRACT. The RECORDSUMMARY operand is valid on either the DEFAULT or the PRINT
command. There are two values for RECORDSUMMARY: RECORDSUMMARY=CLUSTER specifies
that each report line will represent a VSAM cluster or non-VSAM data set, and
RECORDSUMMARY= COMPONENT specifies that each report line will reflect a VSAM
component or non-VSAM data set.
For this feature to work, the input must be sorted by cluster and data set name.
The output from CATARCH and CATVTOC is always sorted in this sequence; when running
with DATATYPE of EXTRACT, you may need to provide the appropriate SORT command.
Note: The BREAK option of the SORT command will not be honored when RECORDSUMMARY
is in effect. It is possible, however, to use the SUM=YES operand or the SUMMARY
command to obtain final totals and to control their format.
Collect and report information about multi-volume clusters:
XSELECT XDSN=TEST.MV.**
PRINT DATATYPE=CATVTOC,RPTYPE=DATA
CANCEL
REPORT FIELD=(NAME,VOL,VOLSQ,COMPTYPE,CATVOLCT,SIZE,SIZEFREE,SIZEUSED)
PRINT DATATYPE=EXTRACT
This results in the following output:
ENTRY NAME VOLSER VSQ CPTYP CVC ALLOC FREE USED
---------- ------ --- ----- --- ----- ---- ----
TEST.MV.A.CLUSTER SMS812 1 DATA 1 135 15 120
TEST.MV.A.CLUSTER SMS812 1 INDEX 1 3 2 1

TEST.MV.B.CLUSTER SMS813 3 DATA 3 930 30 900
TEST.MV.B.CLUSTER SMS813 1 INDEX 1 6 2 4
Example 1b:
Continuing to use the same extract file,
you can summarize the clusters like this:
PRINT DATATYPE=EXTRACT,RECORDSUMMARY=CLUSTER
This results in the following output:
ENTRY NAME VOLSER VSQ CPTYP CVC ALLOC FREE USED
---------- ------ --- ----- --- ------ ---- ----
TEST.MV.A.CLUSTER SMS812 1 DATA 1 138 17 121
TEST.MV.B.CLUSTER SMS811 1 ATA 3 2676 32 2644
Example 2:
Summarize multi-volume data sets from
an extract file:
DEFAULT SORTALLOCATE=(YES,CYL),WORKDD=5,WORKSPACE=500
SORT FIELD=(NAME,DSN,VOLSQ)
REPORT FIELD=(NAME,VOL,VOLSQ,CATVOLCT,SIZE,SIZEFREE,SIZEUSED)
PRINT DATATYPE=EXTRACT,RECORDSUMMARY=COMPONENT
This results in the following type of
output:

How can I report on OFFLINE units?
A new field, UCBSTATS, has been added for reporting
as well as for XSELECT/XEXCLUDE. UCBSTATS has two possible values-ONLINE
and OFFLINE.
Example:
Report on all offline units with addresses
of 20Cx.
REPORT FIELD=(UCBSTATS,VLDEFAUL)
XSELECT UNIT>=20C0,UNIT<=20CF,UCBSTATS=OFFLINE
PRINT DATATYPE=VOLDATA,ENABLE=FASTPATH
This results in the following output:
UCBSTAT VOLSER DEVTYPE UADR VTINDX USEATTR USERS ALOTR %TU FRTRK LFCYL LFTRK FREXT FRAG
------- ------ ------- ---- ------ ------- ----- ------ --- ---- ----- ----- ----- ----
OFFLINE SH20C7 3390 20C4 NONE UNKNOWN 0 2 1 33388 2225 33388 1 0
OFFLINE SH20CE 3390 20CA NONE UNKNOWN 0 16230 98 465 31 465 1 0
Can I report on both OFFLINE and ONLINE data
sets?
Yes, ENABLE=SELECTOFFLIN specifies that offline
DASD units selected using the UNIT or VLUNIT operand on the XSELECT command(s)
be included in the processing.
Note that SELECTOFFLIN is only honored if FASTPATH is enabled and when DATATYPE=VTOC
or VOLDATA is active.
Example:
Summarize the number of data sets that
are on OFFLINE and ONLINE units in the range 20C0-20FF:
XSELECT UNIT>=20C0,UNIT<=20FF
DEFAULT ENABLE=(FASTPATH,SELECTOFFLIN)
SUMMARY FIELD=(UCBSTATS,DSN,SIZE,SIZEFREE,SIZEUSED)
SORT FIELD=(UCBSTATS),BREAK=YES
PRINT RPTYPE=NONE
This results in the following output:

How does FDRPAS handle multi-volume data sets?
FDRPAS is not sensitive to multi-volume data
sets. Since FDRPAS swaps one volume at a time, to a like device, in a manner
that is transparent to the system and applications, it can swap volumes
containing pieces of multi-volume data sets with no special considerations.
Applications will be unaware that part of the data set has been moved to
a new device and part may still be on an older device.
How does FDRPAS handle HFS and zFS data sets?
HFS (Hierarchical File System) data sets are
used with z/OS UNIX System Services (USS), the UNIX component of z/OS and
OS/390. FDRPAS is not sensitive to HFS data sets. Volumes containing HFS
data sets can be swapped even when they are in use.
Likewise, zFS data sets are a new format used by USS, based on a VSAM linear
cluster. Volumes containing zFS data sets can also be swapped without problems
or any special considerations.
What FDR & ABR RESTORE parameters
are recommended at a disaster recovery site?
SMSPROT=NONE and CONFMESS=NO are strongly recommended.
By default, FDR and ABR full-volume restore requires confirmation from the operator,
to prevent accidental overlay of a volume. But at a disaster site, where hundreds
or thousands of volumes must be restored, this confirmation is useless. CONFMESS=NO
will suppress it and speed up the restores.
Likewise, backups of SMS volumes can normally only be restored to SMS-managed
volumes. But at a DR site, you are probably restoring under a starter system
where the target volumes are not marked as SMS. SMSPROT=NONE allows the SMS volumes
to be restored. The SMS volumes will have the correct SMS attributes when the
full system is IPLed.
Note: ABR users who license FDRDRP can significantly
reduce elapsed time when recovering from incremental backups on high capacity
tape.
How can I improve the performance of FDRINSTANT
for ABR (the SPLIT, PSPLIT, SNAP, or FCOPY step)?
The number of //TAPEx DD DUMMY statements controls how many FDRINSTANT subtasks
execute concurrently; each subtask processes one disk volume at a time. To increase
the number of volumes that are processed concurrently, add more //TAPEx DD DUMMY
statements (and TAPExx DDs if needed to specify retentions). Up to 9 TAPEx DDs
are supported. The number of TAPEx DDs in the SPLIT/PSPLIT/SNAP/FCOPY step can
be more than are used in the actual DUMP step.
If you run several ABR jobs in parallel, each with a number of TAPEx DDs, you
can usually process hundreds of volumes in just a few minutes.
How can I release an FDRINSTANT copy?
Sometimes you want to backup an FDRINSTANT point-in-time copy with PGM=FDR or
FDRDSF, but you don't want to release the copy immediately, perhaps because you
want to use it for another purpose. To do so, you omit the REL or RET subparameter
of BCV=, FCOPY=, SNAP= or PPRC=, e.g., code SNAP=USE instead of SNAP=(USE,REL).
To release the point-in-time copy, use a simple FDRDSF step like this:
//RELEASE EXEC PGM=FDRDSF,REGION=0M
//SYSPRINT DD SYSOUT=*
//TAPE1 DD DUMMY
//DISK1 DD UNIT=SYSALLDA,
// VOL =SER=vvvvvv,DISP=OLD
DUMP TYPE=DSF,DSN=VTOC,SNAP=(USE,REL)
How can I improve FDR's backup performance?
The DUMP parameter RTC=YES is strongly recommended,
especially if the disks are attached via FICON channels. RTC=YES:
- Reads and writes up to 1 cylinder of data per I/O.
- Moves disk buffers above the line, allowing more backups to run concurrently
in one DUMP step.
Custom zap C-54.0905 will make RTC=YES the
default in V5.4. You can download the zap from the Innovation FTP site
or request it from Innovation.
