Storage partitions
Storage partitions are used to implement Policy-based High Availability solution. Partitions contain volumes, volume groups, hosts, and host-to-volume mappings.
- All volumes are in volume groups.
- Mappings can only be created between volumes and hosts in the same partition.
Each partition that is associated with an HA replication policy has two properties - the preferred management system and the active management system.
All configuration actions on a storage partition must be performed on the active management system. The storage partition can be monitored on either system.
The preferred management system is the system that you would like to be the active management system under ideal conditions. In the event of a situation where the active management system and the preferred management system are not the same system, the system will automatically failover the active management system back to the preferred management system when it is able. The preferred management system can be changed by the user.
You can configure additional volumes, volume groups, hosts, and host-to-volume mappings at any time, either by adding to an existing partition or by creating a new one.
