The following changes are made for z/OS Version 2 Release 1 (V2R1) as updated February,
2015. Technical changes for this revision are indicated by a vertical line to the left of the
change.
New
- Support for Multi-Target Mirror
environments. For details, refer to Choosing Multi-Target Mirror.
- PSETCHAR request type, to set PPRC volume pair characteristics, including
whether the indicated pair is to be used for a Preserve Mirror function in a Multi-Target Mirror configuration. For more information, refer to PSETCHAR – set PPRC volume pair characteristics, Subparameters for REQUEST=PSETCHAR, PSETCHAR (PPRC set characteristics of volume pair), Converting to Multi-Target Mirror and Defining resource profiles in the RACF Facility class.
- Message ANTP7026I, issued for a RQUERY DVCSTAT or STAT4C request in a
Multi-Target environment. For more information, refer to Querying Global Mirror summary output at device level.
- Support for multiple Incremental FlashCopy targets, with Incremental
FlashCopy Version 2. For more information, refer to Incremental FlaschCopy.
- Support for workload-based write pacing. For more information, refer to Workload-based write pacing, and the description of the new WorkloadWritePacing parameter in
ANTXIN00 parmlib parameters.
- The XFEATURES parameter on the XQUERY STORAGECONTROL command, to show information related to
workload-based write pacing. For more information, refer to XQUERY–Querying a session and XQUERY storage control XFEATURES report.
- The XFEATURES parameter on XQUERY requests using ANTRQST or ANTTREXX. For more information,
refer to ANTRQST and ANTRQSTL macros – call to the system data mover API and REXX support for the ANTRQST API.
Changed
- The ACTION parameter on PPRC Establish functions now accepts MTFAILOVER, to
establish a Multi-Target Mirror configuration. For more
information, refer to Adding a PPRC volume pair, Subparameters for REQUEST=PESTPAIR, and
PESTPAIR (PPRC establish volume pair).
- The value for STATE in formatted output for CQUERY shows new values (MTIR
and UNKNOWN) related to Multi-Target Mirror. In addition, the
output for CQUERY VOLUME and CQUERY PATHS is expanded. For more information, refer to Identifying Peer-to-Peer Remote Copy volume states, Fields in formatted output, CQUERY formatted output in a multi-target configuration, and CQUERY formatted output with the PATHS option in a Multi-Target configuration.
- RVOLUME JOIN requests now accept MTVOLLIST and MTVOLRANGE, for Multi-Target
Global Mirror sessions.For more information, refer to RVOLUME – manage volumes for Global Mirror session, Subparameters for REQUEST=RVOLUME, and RVOLUME (Global Mirror manage volumes).
- The output for a RQUERY DVCSTAT request includes an additional ANTP7026I message in a
Multi-Target environment. For more information, refer to Querying Global Mirror summary output at device level.
- In a PPRC configuration, you can now attach up to 16 recovery site logical subsystems to each
primary site logical subsystem. For more information, refer to Examining PPRC configuration options and
Table 1.
- Incremental FlaschCopy is updated to reflect Incremental FlashCopy V2.
- Optional parameters for the FCESTABL command is updated to indicate that PREFERRED is
not supported in a Multi-Target Mirror configuration.
- XQUERY volume pace report is updated for workload-based write pacing.
- The descriptions of ON for DVCBLOCK are changed to reflect workload-based write pacing, in XADDPAIR–Adding volume pairs or utility volumes and XSET–Changing session parameters, Adding a volume with the LOGPLUS option, Subparameters for REQUEST=XADD, Subparameters for REQUEST=XSET, XADD (XRC add volume pair),
and XSET (XRC session parameters).
