Support for dynamic LUN expansion in FSS environments

Volume Manager (VxVM) provides the ability to grow the existing storage by growing the LUN, which is termed as Dynamic LUN Expansion (DLE). This feature is supported with both, private and shared (CVM configurations) disk groups, where the disks are exclusively connected to all the hosts in the cluster.

Beginning with this InfoScale release, DLE is also supported with FSS configurations in which disks are connected with each cluster node and accessible to other nodes through network interconnect. To use the DLE feature, you invoke the vxdisk resize command with the length option from the master node in an FSS configuration. Alternatively, you can use the Management Server console of InfoScale Operations Manager to resize a disk, which internally invokes this command. The command intelligently detects the remote disks and gets the required protocol executed to complete the LUN expansion; you do not need to specify any additional options. No explicit master switching is required.

For details on growing the existing storage by growing the LUN, refer to the platform-specific Storage Foundation 9.0 Administrator’s Guide.
