The planning steps you must consider to successfully install the
TS1130 tape drive software, vary depending upon the tape environment
you have installed. Table 1 discusses planning
considerations for stand-alone environments (including tape devices
installed in vendors' automated tape libraries) and for IBM tape
library environments.

drive planning considerationsArea |
Planning Considerations |
---|
System customization: stand-alone
environment |
- Determine which data needs to be encrypted and set up the appropriate
data class policy specifying EEFMT3 (or EEFMT2 for media interchanges).
Also specify, as appropriate, the non-encryption recording formats,
EFMT3 (or EFMT2 for media interchanges). If a TS1130 tape drive
tape drive is allocated, the default recording format is EFMT3. Also,
modify or create ACS routines to associate the tape output functions
with a data class that has the appropriate recording format specified.
- As appropriate, determine which key labels are to be used and
how they will be specified, data class, the DD statement or Encryption
Key Manager established defaults.
- Determine whether you will need help from your tape management
system vendor and contact them, if needed.
- As appropriate, plan for the installation of the Encryption Key
Manager (EKM) and decide which of the supported key stores to use.
- As appropriate, plan for the key labels that will be used and
the encoding mechanism (label or hash) for each and where the key
labels will be specified.
- For in-band key management (with encryption), update the IOS PARMLIB
member (IECIOSxx) using the EKM command. Also create a z/OS UNIX segment for the IOS address space.
- Upgrade 3592 Model J1A and 3592 Model E05 drive microcode to
enable the drives to recognize and enable the EFMT3 and EEFMT3 formatted
cartridges to be relabelled/reused. Also, ensure that VOLNSNS=YES
is in the DEVSUPxx member of PARMLIB.
- Determine which systems should have coexistence support and which
systems should have full support.
- Determine when to IPL the host machine after installing the coexistence
PTFs, if needed.
- Determine when to IPL the host machine after installing all necessary
PTFs.

- Determine which data needs to be encrypted and set up the appropriate
data class policy specifying EEFMT3 (or EEFMT2 for media interchange).
Also, specify as appropriate, the non-encryption recording formats,
EFMT3 or EFMT2 (for media interchange). If a TS1130 tape drive is
allocated, the default recording format is EFMT3. Also, modify or
create ACS routines to associate the tape output functions with a
data class that has the appropriate recording format specified.
- Because the 3592 Model E06 is only downward read (and not write)
compatible with the EFMT1 format, you must specify the read-compatible
special attribute indicator (in the tape configuration database) or
use LABEL=(,,,IN) on the DD statement of JCL to enable the 3592 Model
E06 drive to be considered eligible for an EFMT1 request.
- As appropriate, determine which key labels are to be used and
how they will be specified, data class, the DD statement or Encryption
Key Manager established defaults.
- Determine whether you will need help from your tape management
system vendor and contact them, if needed.
- As appropriate, plan for the installation of the Encryption Key
Manager (EKM) and decide which of the supported key stores to use.
- As appropriate, plan for the key labels that will be used and
the encoding mechanism (label or hash) for each and where the key
labels will be specified.
- For in-band key management (with encryption), update the IOS PARMLIB
member (IECIOSxx) using the new EKM command. Also create a z/OS UNIX segment for the IOS address space.
- Upgrade 3592 Model J1A and 3592 Model E05 drive microcode to
enable the drives to recognize and enable the EFMT3 and EEFMT3 formatted
cartridges to be relabelled/reused. Also, ensure that VOLNSNS=YES
is in the DEVSUPxx member of PARMLIB.
- Identify the installation exit changes that are needed.
- Determine which systems should have coexistence support and which
systems should have full support.
- Determine when to IPL the host machine after installing the coexistence
PTFs, if needed.
- Determine when to IPL the host machine after installing all necessary
PTFs.

System customization: OAM object tape environment |
The planning steps that you must consider in tape environments
that use OAM objects vary depending upon the type of environment that
is installed.
- If you install the TS1130 tape drive devices in a stand-alone
environment:
- Follow the system customization planning steps listed for a stand-alone
environment.
- Determine the esoteric or generic device names that need to be
added to STORAGEGROUP statements in the CBROAMxx member of
PARMLIB for the object storage groups that are to use the new devices.
- Determine whether to use the global keyword DSNWITHSGNAME on the
SETOAM statement in the CBROAMxx member of PARMLIB to append
the object storage group name to the OAM object tape data set names.
See Object tape data set low-level qualifier enhancement for additional information.
- Determine the new data classes that need to be defined in STORAGEGROUP
statements in the CBROAMxx member of PARMLIB for the object storage
groups that are to use the new encryption format EEFMT3 (by default,
the non-encryption recording format EFMT3 is used).
- If you install the TS1130 tape drive devices in an IBM tape library:
- Follow the system customization planning considerations listed
for an IBM tape library environment.
- Determine the new data classes that need to be defined in STORAGEGROUP
statements in the CBROAMxx member of PARMLIB for the object storage
groups that are to use the new devices and the new encryption format
EEFMT3.
- In addition, if you install the TS1130 tape drive devices in an
OAMplex:
- Ensure that the TS1130 tape drive devices are available to all
instances of OAM where the full support software is installed.
- Determine whether systems exist that will require coexistence
support. This situation is particularly important in an OAMplex where
at least one system has the full-support software installed and enabled,
and at least one system will not have all of the support installed
or enabled. Coexistence support is needed if not all of the systems
in the OAMplex will be at the same full-support level.
- To provide this coexistence support, as appropriate for the support
and the release level, install the OAM full-support PTF without the
enabling PTF or any separate coexistence support PTF.
- Determine when to IPL the host machine after installing the coexistence
PTFs, if needed.
- In an OAM Object Tape environment, any coexistence or full support
systems must also have the new overflow-related columns added to the
TAPEVOL table in the Optical Configuration Database (OCDB). Only one
system in an OAMPlex needs to run CBRSMKBO sample JCL to add the new
TAPEVOL columns, but all systems in the OAMplex need to run CBRPBIND.
Adding the new TAPEVOL columns and running CBRPBIND is needed with
the installation of the PTFs regardless of whether the new TS1130
tape drives are being used.

Storage administration: stand-alone
tape environment |
- Determine how to setup your tape management systems pooling support
to segregate rewritable (MEDIA5, MEDIA7, and MEDIA9) and WORM (MEDIA6,
MEDIA8, and MEDIA10) media and also to segregate the standard, economy,
and extended length cartridges, as appropriate for your job and application
usage.
- Review the usage of the DEVSUPxx PARMLIB option, ENFORCE_DC_MEDIA,
(optional) to ensure that the media type mounted is the media type
requested through data class. This can be used in conjunction with
the tape management systems pooling support as an additional safety
check.
- Review the existing SMS data class media policies to ensure compatibility
with existing tape scratch pool policies before enabling the DEVSUPxx PARMLIB option, ENFORCE_DC_MEDIA.
- Review the existing SMS data class recording technology policies
to ensure that data set policies set to EFMT2 and EEFMT2 are being
appropriately used. If a TS1130 tape drive is allocated and the specified
data class indicates EFMT2 or EEFMT2, the drive will record in the
lower recording technology. Also, remember that the TS1130 does
not record in the EFMT1 format, so also review any existing SMS data
classes that specify EFMT1 for applicability.
- Determine the data class updates that are needed to request the
appropriate recording format for the TS1130 tape drives. If a TS1130
tape drive is allocated, the default recording format is EFMT3 (non-encryption).
- Determine if media should use performance segmentation, with a
fast access segment to be filled first, and a slower access segment
to be filled after. If you decide to use the performance segmentation
attribute (available with MEDIA5 and MEDIA9 tape cartridges only,
and mutually exclusive with performance scaling), you can:
- Define a data class that requests performance segmentation.
- Modify or create ACS routines to associate the tape output functions
using performance segmentation with a data class that requests performance
segmentation.
- Determine if media should be used at full capacity or scaled for
optimal performance. If you decide to use the performance scaling
attribute (available with MEDIA5 and MEDIA9 tape cartridges only),
you can:
- Define a data class that requests performance scaling.
- Modify or create ACS routines to associate the tape output functions
using performance scaling with a data class that requests performance
scaling.
- Determine how to allocate media to appropriate nonlibrary drives.
Consider using the IBM manual tape library. You can also segregate
the real drives from the emulating drives, use third-party tape management
software, or use customer-written applications.
- Identify any needed changes to the hardware configuration definition
(HCD) to define the new devices.

Storage administration: IBM tape library
environment |
- Review the usage of the DEVSUPxx PARMLIB option, MTL_NO_DC_WORM_OK,
if the WORM cartridges in the manual tape library environment will
be mounted through use of the tape management systems pooling support
versus a data class WORM media specification.
- Determine the 3592 media usage of rewritable (MEDIA5, MEDIA7,
and MEDIA9) and WORM (MEDIA6, MEDIA8, and MEDIA10) media and also
the usage of the standard, economy, and extended length cartridges.
Then make the appropriate data class definition updates to select
the appropriate media type. WORM media can only be used if explicitly
requested through data class.
- Review ACS routines for changes needed in selecting tape storage
groups and libraries that have the TS1130 tape drive devices.
- Determine the data class updates that are needed to use the recording
technology, media type, and performance scaling or performance segmentation
data class attribute (performance scaling or segmentation available
with MEDIA5 and MEDIA9 tape cartridges only).
- Identify any needed changes to the HCD to define the new devices.
- To define the partitioning category code for MEDIA5, MEDIA6, MEDIA7,
MEDIA8, MEDIA9, and MEDIA10 tape cartridges, specify the appropriate
parameter of the DEVSUPxx parmlib member.
- Because the 3592 Model E06 is only downward read (and not write)
compatible with the EFMT1 format, you must specify the read-compatible
special attribute indicator (in the tape configuration database) or
use LABEL=(,,,IN) on the DD statement of JCL to enable the 3592 Model
E06 drive to be considered eligible for an EFMT1 request.

Storage administration: OAM object tape
environment |
The planning steps that you must consider in tape environments that
use OAM objects vary depending upon the type of environment that is
installed.
- If you install the TS1130 tape drive devices in a stand-alone
environment, follow the storage administration planning steps listed
for a stand-alone environment.
- If you install the TS1130 tape drive devices in an IBM tape library:
- Follow the storage administration planning steps listed for an
IBM tape library environment.
- Review ACS routines for STORE or CTRANS environments and make
any changes needed to ensure proper class assignment.
- If you install the TS1130 tape drive devices in an OAMplex, you
must make the devices available to all instances of OAM where the
full support is installed.

Tracking Data Written: An application
may track in KBs, data such as the number of logical bytes written,
the number of physical bytes written, the amount of free space remaining
on a volume, the capacity of the volume, or the number of logical
bytes deleted. Now, with a 1 TB tape (non-compressed), the possibility
exists with the 3592 Model E06 to overflow some of the 4-byte fields
that contain these values. Of particular concern would be the logical
data-related fields that (with compression) deal with an amount of
data that may be larger than the physical capacity of the tape.
Applications that use, store, and display this type of information
may need to account for and determine how best to handle an overflow
situation. For a signed (4-byte) integer X'7F FF FF FF' (2,147,483,647
in KBs) supports 2+ TBs and for an unsigned (4-byte) integer X'FF
FF FF FF' (4294967295 in KBs) supports 4+ TBs.
