2.2.5.1 Solstice DiskSuite Considerations

Consider these points when planning Solstice DiskSuite configurations:

• Always use trans metadevices for file systems within disksets.

• If you run with only two disk expansion units, you will need to use Solstice DiskSuite mediators.

• When using Solstice DiskSuite mediators with any disksets in your configuration, only two cluster nodes can act as mediator hosts. Those two nodes must be used for all disksets requiring mediators, regardless of which nodes master those disksets. Therefore, in Sun Cluster configurations with more than two nodes, it is possible for a diskset's mediator host to be one that is not actually a potential master of that diskset.
