|Abstract: PowerHA/XD Version 5.5 expands support to include the asynchronous mirroring option for GLVM. Please be aware that GLVM 5.5 (regardless of sync or async) requires AIX 6.1. Asynchronous mode currently does not support using the enhanced concurrent volume group type.|
|IBM PowerHA supports Asynchronous Mirroring Option for GLVM|
March 26, 2009
IBM* PowerHA* (formerly HACMP*) for AIX*, Version 5.5 with the PowerHA/XD optional feature, expands support to include the asynchronous mirroring option for GLVM.
Please refer to the following information for support details.
PowerHA V5.5 SP1
AIX 6.1 TL2 SP3
- Geographic Logical Volume Manager (GLVM) provides data replication over IP networks for use in disaster recovery solutions. GLVM supports two modes for replication: Synchronous replication and Asynchronous replication.
More information can be found in the Geographic LVM: Planning and Administration Guide.
- PowerHA/XD GLVM Asynchronous support requires PowerHA APAR IZ31205 and IZ31207 (included in PowerHA V5.5 SP1), and AIX APAR IZ31208 (included in AIX V6.1 TL2 SP3). IBM recommends the software levels stated in the above table.
- If it is necessary to change the configuration of a geographically mirrored volume group - such as, to replace a failed disk, or to extend the volume group - it is necessary to bring the volume group off-line and on-line again. IBM intends to remove this restriction in the future.
