Configuration Requirements for Highly Available Local File Systems

Any file system on multihost disks must be accessible from any host that is directly connected to those multihost disks. To meet this requirement, configure the highly available local file system as follows:

  • Ensure that the disk partitions of the local file system reside on global devices.

  • Set the AffinityOn extension property of the HAStoragePlus resource that specifies these global devices to True.

    The Zpools extension property of the HAStoragePlus resource ignores the AffinityOn extension property.

  • Create the HAStoragePlus resource in a failover resource group.

  • Ensure that the failback settings for the device groups and the resource group that contains the HAStoragePlus resource are identical.


Note -  The use of a volume manager with the global devices for a highly available local file system is optional.
