7.5 HA 5.5.2, 7.4 HA 4.11.2 PTFs

Open

IBM PowerHA SystemMirror for IBM i 7.5 with HA version 5.5.2 and 7.4 with HA version 4.11.2 brings strategic enhancements centered around integration. This release integrates with IBM FlashSystem asynchronous policy-based replication and continues to enhance the administrative domain.

IBM FlashSystem Asynchronous Policy-based Replication 7.5 HA 5.5.2 7.4 HA 4.11.2

PowerHA has a long history of integrating with IBM Spectrum Virtualize-based storage, including IBM FlashSystem, with built-in native support for technologies including Metro Mirror, Global Mirror, LUN-level switching, and FlashCopy.

With this enhancement, PowerHA adds integration with IBM Spectrum Virtualize asynchronous policy-based replication. PowerHA automatically detects if replication is configured with asynchronous policy-based or consistency-group-based replication, enabling the use of the same configuration and management commands with minimal changes to the user experience. In addition, it is possible to combine technologies, including LUN-level switching and PowerHA’s native FlashCopy integration and automation with policy-based replication.

Enhanced Administrative Domain Integration 7.5 HA 5.5.2 7.4 HA 4.11.2

The administrative domain in PowerHA synchronizes security and configuration-related objects across a PowerHA environment, including user profiles, job descriptions, and printer device descriptions, so that changes to resources monitored by the administrative domain are automatically synchronized with the other nodes.

The administrative domain now includes support for synchronizing SNMPv3 attributes on printer device descriptions, including the SNMP user name (SNMPUSR) and SNMP context name (SNMPCNTX) attributes. Existing monitored resources in the administrative domain that previously monitored all attributes for printer device descriptions will automatically begin monitoring the new attributes after all nodes are updated to a PowerHA version supporting the new attributes.
