IBM PowerHA SystemMirror for IBM i

June 2019

Version PTF 7.2/7.3 SI70186

NOTE: PTF update SI70186 applies to both the 7.2 and the 7.3 releases of the Operating System. Information about PowerHA for i, additional PTF groups, and recommended fixes, visit the IBM PowerHA SystemMirror for i pages in the IBM developerWorks wiki.

Enhancements
  • Communication to the SVC has been enhanced for robustness in certain heavily loaded environments where the SVC communication fails with ssh_exchange_identification: Connection closed by remote host. PowerHA has implemented connection retries when this error is encountered.
Other Fixes
  • SE69755: DSPASPSSN for geographic mirroring has been corrected to display accurate geographic mirroring status during a cluster partition.
  • SE70374: PowerHA environments utilizing DSCLI have been corrected to work in all CCSIDs. Previously, some PowerHA commands would fail in some job CCSIDs with message HAE2013.
  • SE71270: DSCLI communication within PowerHA has been enhanced to support passwords up to 16 characters long. Previously passwords longer than 14 characters resulted in an HAE2024 with CMMCI9026E Unmatched ' characters.
  • In some instances the CHGHAPCY command with invalid input incorrectly reported success even though the operation failed. CHGHAPCY has been enhanced to perform additional validation and error reporting.
  • In a HyperSwap with Global Mirror environment, in some instances CHGCSMSSN with the option of *REATTACH failed with an HAE2057. PowerHA has been corrected to allow the reattach of a detached Global Mirror in these instances.
  • In some instances CHGHYSSTS *START would incorrectly report success even if an I/O path was not available to both DS8000 storage devices.
  • PowerHA has been corrected to no longer create or delete proxy commands for temporary PTF objects in QSYS.
Version 7.4

NOTE: PTF SI70216 is a required PTF for the the 7.4 version of PowerHA. Failure to install the PTF will result in the following message:

The IBM PowerHA SystemMirror for i licensed program is missing required program temporary fixes (PTFs). Install the required PTFs and try the request again. If the problem persists, contact your service provider for further assistance.

New Features
  • PowerHA contains support for Copy Services Manager (CSM) Metro Mirror, Global Mirror, and HyperSwap with Global Mirror.
  • PowerHA SystemMirror for i standard edition integrates with Db2 Mirror for i to provide support for near-continuous availability of IFS data within a Db2 Mirror for i environment.
  • CRG containers that serve as a control object for a collection of CRGs to be managed as a single entity.
  • The PowerHA SystemMirror for i enterprise edition enables Db2 Mirror disaster recovery capability through the use of new CRG containers.
  • PowerHA supports customizing and controlling behaviors in a PowerHA and cluster environment via HA Policies. The following policies are initially supported:
    • Automate the addition of Monitored Resource Entries (MREs) across nodes in the administrative domain upon object creation with the QCST_AD_CREATE policy.
    • Automate the deletion of MREs across all nodes in the administrative domain upon object deletion with the QCST_AD_DELETE policy.
    • Honor the restore of attributes on MREs in the administrative domain upon system save and restore operations with the QCST_AD_RESTORE policy.
    • Integrated control over the ability to cancel automatic CRG failovers with the QCST_CRG_CANCEL_FAILOVER policy.
    • Control the configuration of security settings governing communication between PowerHA and a storage device using IBM Copy Services Manager (CSM) with the QHA_COMM_STRICT_CERT_CHECK policy.
Enhancements
  • Additional customization on device CRGs with a new vary online setting of *CURRENT.
  • Improved control over administrative domain synchronization options with the STRCAD command.
  • Continued improvements to reduce IASP vary on times.
  • Communication to the SVC has been enhanced for robustness in certain heavily loaded environments where the SVC communication fails with ssh_exchange_identification: Connection closed by remote host. PowerHA has implemented connection retries when this error is encountered.
Other Fixes
  • SE70374: With certain job ccsids, ASP session commands failed with error HAE2013. This has been corrected to no longer occur.
  • SE69755: DSPASPSSN for geographic mirroring has been corrected to show the correct replication and ASP vary status when the cluster has a node with a status of partition.
  • SE71270: DSCLI communication within PowerHA has been enhanced to support passwords up to 16 characters long. Previously passwords longer than 14 characters resulted in an HAE2024 with CMMCI9026E Unmatched ' characters.
  • PowerHA has been corrected to no longer create or delete proxy commands for temporary PTF objects in QSYS.

April 2019

Version PTF 7.2/7.3 SI69233 (plus language PTFs)

NOTE: PTF update SI69233 applies to both the 7.2 and the 7.3 releases of the Operating System. Information about PowerHA for i, additional PTF groups, and recommended fixes, visit the IBM PowerHA SystemMirror for i pages in the IBM developerWorks wiki.

New Features
  • Integration of PowerHA IASP-based replication with IBM Copy Services Manager for DS8000 Metro Mirror and DS8000 Global Mirror replication solutions.
  • PowerHA has been enhanced to enable DS8000 HyperSwap configuration in conjunction with Global Mirror for regional outage protection.
Enhancements
  • The RPG Header files located in QHASM/QRPGLESRC for PowerHA APIs have been enhanced to use free-form RPG for easier usability and readability.
Other Fixes
  • When one or more storage devices are down or inaccessible, HyperSwap status screens and APIs now properly show the HyperSwap status as unknown, instead of reporting a potentially incorrect cached status.
  • PowerHA has been updated so that it no longer leaves QHASM in the product portion of the library list after the execution of commands.

  • The number of HAC0026 and CPCBB01 joblog messages that contain a reason code of success, on many PowerHA commands has been reduced for enhanced usability.
  • The ADDHACFGD and CHGHACFGD command parameter HYSSTGTYPE has been renamed to SUBTYPE. Any existing CL programs that use these commands may require modification.

  • The CHGHYSSTS command default parameter for ASP device has been changed from *ALL to *SYSBAS. The *ALL option for the ASP device parameter is no longer available. Any existing CL programs that use these commands may require modification.

NOTE: PTF update SI69233 requires one or more associated language PTFs. To determine if additional languages you have installed in your environment require a requisite MRI PTF, consult the table of language PTFs in the release cover letter at IBM Support.

September 2018

Version PTF 7.1 SI68260, 7.2/7.3 SI68212
Other Updates

  • SE69857 PowerHA has been updated to only log HAI2002 in QSYSOPR a single time once cross site mirroring becomes synchronized.

NOTE: PTF update SI68212 applies to both the 7.2 and the 7.3 releases of the Operating System. Information about PowerHA for i, additional PTF groups, and recommended fixes, visit the IBM PowerHA SystemMirror for i pages in the IBM developerWorks wiki.

July 2018

Version PTF 7.2/7.3 SI67828
Other Updates

  • SE68810 PowerHA has been updated to properly handle the authorities needed to perform an automatic HyperSwap during a Live Partition Mobility operation.
  • SE69047 In order to prevent extra HAI000C from being sent to QSYSOPR, PowerHA only verifies that the *CIMOM server is active on the system if there is a cluster monitor of type *CIMSVR. The HAI000C will no longer be sent to QSYSOPR in environments that do not have a *CIMSVR cluster monitor.

NOTE: PTF update SI67828 applies to both the 7.2 and the 7.3 releases of the Operating System. Information about PowerHA for i, additional PTF groups, and recommended fixes, visit the IBM PowerHA SystemMirror for i pages in the IBM developerWorks wiki.
