## Verifying Storage Node configuration

You can use the `diagnostics verify` tool to verify the configuration of the specified Storage Nodes. You can also check if the configuration of each Storage Node is consistent with other members of the cluster.

The usage of this command is:

    diagnostics verify { -checkLocal | -checkMulti }
    [-host <host name of a SN in topology>]
    [-port <registry port of a SN in topology>]
    [-sshusername <SSH username>]
    [-username <store username>]
    [-security <security-file-path>]
    [-configdir <location of Storage Node target file>]

where:

- -checkLocal

  If specified, verifies the configuration of the specified Storage Nodes.

- -checkMulti

  If specified, verifies that the configuration of each Storage Node is consistent with other members of the cluster.

- -host

  Specifies the host of a Storage Node. If specified, it detects a running topology in order to update the `sn-target-list` without having to run `diagnostics setup` first. It needs to be specified with -port.

- -port

  Specifies the host of a Storage Node. If specified, it detects a running topology in order to update the `sn-target-list` without having to run `diagnostics setup` first. It needs to be specified with -host.

- -sshusername

  Specifies a SSH username to log on as in a Storage Node.

- -username

  Specifies a username to log on as in a secure deployment.

- -security

  In a secured deployment, specifies a path to the security file. If not specified in a secure store, updating the `sn-target-list` will fail.

- -configdir

  Specifies the directory which contains the `sn-target-list`. If the flag is not specified, the default directory is the working directory.
