Administering IBM Storage Scale Erasure Code Edition

Physical disk procedures
This topic describes the various procedures that you can perform for the maintenance of disks.
Export and import of file systems based on ECE recovery groups
IBM Storage Scale Erasure Code Edition offers support for exporting and importing file systems based on vdisks within recovery groups. This feature can be used to move one or more file systems from one cluster to another, or to temporarily remove file systems from a cluster and restore them later.
Virtual disk procedures
The mmvdisk command can be used to manage IBM Storage Scale Erasure Code Edition storage. The commands for listing individual or groups of virtual disks (vdisks), and for defining, creating, and deleting groups of virtual disks (vdisk sets) are available.
Node procedures
This topic describes various procedures that can be done on a node to accomplish various tasks.
