  • 1.  PowerHA single node "cluster" ?

    We are planning a DR site, in which a single DR node running AIX 6.1 will use EMC MirrorView replication software to mirror a data Volume Group. During the production site failure, the DR node should:

    (1) Vary on the mirrored data Volume Group
    (2) Mount the file systems
    (3) Create a service IP alias in the DR site subnet / VLAN (different from the production site VLAN / subnet)
    (4) Start the application

    Since PowerHA Enterprise Edition doesn't support EMC MirrorView, we are considering to install PowerHA Standard Edition on the DR site node, and create a single node "cluster", which will enable me to perform all the above actions by bringing a Resource Group online.

    My question is: Is it supported to create a single node PowerHA "cluster" in such a way ?
