The following information can be obtained for the path information about compute nodes with the specified ID.

  • id: Path IDs (character string of initiator ID of the computer node and ID of the compute port for the target operation connected by a comma)

  • serverId: IDs (uuid) of compute nodes

  • hbaName: WWNs, iSCSI names, or host NQNs of initiators for compute nodes

  • hbaId: IDs (uuid) of initiators for compute nodes

  • portId: IDs (uuid) of compute ports of targets with which initiators negotiate

  • portName:

    • For iSCSI connection, iSCSI names of compute ports of targets with which initiators negotiate

    • (Bare metal) For FC connection, WWN of compute ports of targets with which initiators negotiate. Always null for NVMe/TCP connection.

  • portNickname: Nicknames of compute ports of targets with which initiators negotiate

  • vpsId: ID of the VPS to which the compute node path belongs

  • vpsName: Name of the VPS to which the compute node path belongs

  • Required role: Security, Storage, RemoteCopy, Monitor, Service, or Resource

  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. Verify the ID of the initiator for the applicable compute node and the ID of the compute port.

    • For iSCSI connection, if you use the CLI to specify an initiator and compute port by iSCSI name, verify the iSCSI name of the initiator and compute port.

    • (Bare metal) For FC connection, if you use the CLI to specify an initiator and compute port by WWN, verify the WWN of the initiator and compute port.

    • (Bare metal) For NVMe/TCP connection, if you use the CLI to specify an initiator by host NQN, verify the host NQN of the initiator.

    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>/hbas

    CLI: hba_list

  3. Obtain path information about 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: GET /v1/objects/servers/<id>/paths/<hbaId>,<portId>

    CLI: path_show
