Phasing Out a Component
Phases out a component.
component_phaseout component=ComponentId
Parameters:
Name Description Mandatory
component Component identification. Y
This command instructs the system to stop using the component, where the
component can be either a disk, module, switch or UPS.
For disks, the system starts a process for copying the disk's data, so that even
without this disk, the system is redundant. The state of the disk after the command
is Phasing-out.
The same process applies for data modules. The system starts a process for
copying all the data in the module, so that the system is redundant even without
this module. A data module phase-out causes a phase-out for all the disks in that
module.
For UPSs and switches, the system configures itself to work without the
component. There is no phase-out for power supplies, SFPs or batteries.
Phasing out a module or a disk, if it results in the system becoming
non-redundant, is not permitted. Components must be in either OK or a Phase In
status.
