Managing disks
Use the given information to manage disks in IBM Storage Scale.
Disks can have connectivity to each node in the cluster, be managed by network shared disk servers, or a combination of the two. For more information, see mmcrnsd command. Also see, Network Shared Disk (NSD) creation considerations.
Note: A LUN provided by a storage subsystem is a disk for the purposes
of this documentation, even if the LUN is made up of multiple physical
disks.
The disk related tasks performed on a GPFS
file system include:
- Displaying disks in a GPFS cluster
- Adding disks to a file system
- Deleting disks from a file system
- Replacing disks in a GPFS file system
- Additional considerations for managing disks
- Displaying GPFS disk states
- Changing GPFS disk states and parameters
- Changing your NSD configuration
- Changing NSD server usage and failback
- Enabling and disabling Persistent Reserve
