Synopsis
mmdiscovercomp -N {Node[,Node...] | NodeFile | NodeClass} [--dry-run] Availability
Available with the Elastic Storage Server.
Description
The mmdiscovercomp command discovers components and adds them to the configuration.
Parameters
- -N {Node[,Node...] | NodeFile | NodeClass}
- Specifies the nodes to which the command applies.
- --dry-run
- Indicates that the changes resulting from the command are not to be recorded in the configuration file.
Exit status
- 0
- Successful completion.
- nonzero

You must have root authority to run the mmdiscovercomp command.
The node on which the command is issued must be able to execute remote shell commands on any other node in the cluster without the use of a password and without producing any extraneous messages. For additional details, see the following IBM Storage Scale RAID: Administration topic: Requirements for administering IBM Storage Scale RAID.
Examples
To find supported storage enclosures
attached to the nodes of a cluster and add them to the configuration,
enter the following command:
mmdiscovercomp all
The system displays output similar to this:
