Figure 4. Claim storage using the GUI (for HTML5)
The UI supports most of the metro node operations, and includes Dell EMC Online help for metro node to assist new users in
learning the interface.
Metro node operations that are not available in the GUI, are supported by the Command Line Interface (CLI), which supports full
functionality.
Metro node CLI
The metro node CLI supports all metro node operations.
The CLI is divided into command contexts:
● Global commands are accessible from all contexts.
● Other commands are arranged in a hierarchical context tree, and can be executed only from the appropriate location in the
context tree.
The following example shows a CLI session that performs the same tasks as shown in Figure.
Example 1 Claim storage using the CLI:
In the following example, the claimingwizard command finds unclaimed storage volumes, claims them as thin storage, and
assigns names from a CLARiiON hints file:
VPlexcli:/clusters/cluster-1/storage-elements/
storage-volumes> claimingwizard --file /home/service/clar.txt
--thin-rebuild
Found unclaimed storage-volume
VPD83T3:6006016091c50e004f57534d0c17e011 vendor DGC:
claiming and naming clar_LUN82.
Found unclaimed storage-volume
VPD83T3:6006016091c50e005157534d0c17e011 vendor DGC:
claiming and naming clar_LUN84.
Claimed 2 storage-volumes in storage array car
Claimed 2 storage-volumes in total.
VPlexcli:/clusters/cluster-1/storage-elements/storage-volumes>
The Dell EMC CLI Guide for metro node provides a comprehensive list of metro node commands and detailed instructions on
using those commands.
Metro node Element Manager API
Metro node Element Manager API uses the Representational State Transfer (REST) software architecture for distributed
systems such as the World Wide Web. It allows software developers and other users to use the API to create scripts to run
metro node CLI commands.
Metro node Element Manager API supports all metro node CLI commands that can be run from the root context.
