CAUTION:

  • When compute nodes are clustered and the volumes recognized by the compute nodes are online, set the intended volume offline and then delete path information.

  • For FC or iSCSI connection, before you delete path information from a compute node, verify whether the volumes that can be accessed from the compute node are in SCSI-2 Reserve status or SCSI-3 Persistent Reserve status. If the volumes are in either status, release them from the status, and then delete path information.

  • When you change the path information of a compute node, perform a rescan of the storage on that compute node. If the path information already deleted remains on the compute node, it might cause malfunction.

  • Required role: VpsStorage

  1. Verify the ID of the applicable compute node.

    If you use the CLI to specify a compute node by nickname, check the nickname of the compute node.

    REST API: GET /v1/objects/servers

    CLI: server_list

  2. Obtain a list of path information about compute nodes.

    Run either of the following commands with the compute node ID specified.

    If you use the CLI, you can specify a nickname instead of the compute node ID.

    REST API: GET /v1/objects/servers/<id>/paths

    CLI: path_list

  3. Delete path information from the applicable compute node.

    Run either of the following commands with the ID of the compute node, ID of the initiator, and ID of the compute port for the target operation specified.

    If you use the CLI, you can specify nicknames instead of compute node IDs, specify WWNs, iSCSI names, or host NQNs instead of initiator IDs, and specify WWNs or iSCSI names instead of compute port IDs.

    REST API: DELETE /v1/objects/servers/<id>/paths/<hbaId>,<portId>

    CLI: path_delete

    Verify the job ID which is displayed after the command is run.

  4. Verify the state of the job.

    Run either of the following commands with the job ID specified.

    REST API: GET /v1/objects/jobs/<jobId>

    CLI: job_show

    If the job state is "Succeeded", the job is completed.

  5. Obtain a list of path information and verify that the intended path information is deleted.

    Run either of the following commands with the compute node ID specified.

    If you use the CLI, you can specify a nickname instead of the compute node ID.

    REST API: GET /v1/objects/servers/<id>/paths

    CLI: path_list
