Querying Physical Path Information

Querying Physical Path Information

Function

The show path command is used to query information about a specified or all physical paths, including the working status, owning storage system, owning controller, and owning HBA.

Format

show path [ -a array-id | -p path-id ]

Parameters

Keyword and Parameter

Description

Default Value

-a array-id

ID of a storage system.

You can run show diskarray without an ID to display all storage system IDs.

None

-p path-id

ID of a physical path.

You can run show path without an ID to display all physical path IDs.
NOTE:

You can query a maximum of eight physical paths' performance statistics at a time. Use comas (,) to separate physical path IDs.

None

Level

User root

Usage Guidelines

  • Run the show path command to check the working status of all physical paths.
    NOTE:
    When the show path command is executed, you can only view the information about a maximum of eight paths on one controller.
  • Run the show path -a array-id command to check the working status of a specified storage system's physical paths.
  • Run the show path -p path-id command to check the working status of a specified physical path.

Example

  • Check the working status and path IDs of all physical paths.
    ~ # esxcli upadm show path

System Response

The following table explains some parameters in the command output:

Parameter

Description

Default Value

Path ID

ID of the physical path.

None

Initiator Port

Port of the initiator.

NOTE:
For some arrays such as the S2600 and S5500, the initiator ports are displayed as the initiator port IDs in the SCSI address.

None

Target Port

Port of the target.

NOTE:
For some arrays such as the S2600 and S5500, the initiator ports are displayed as the initiator port IDs in the SCSI address.

None

Controller

Name of a controller.
NOTE:

If the controller name is followed by Remote information, the controller is a remote controller.

None

Path State

State of the physical path. Possible values are as follows:
  • Normal: The path is normal.
  • Fault: The path is faulty.
  • I/O discrete error degradation: The path is degraded due to discrete I/O errors.
  • Intermittent failure degradation: The path is degraded due to intermittent failures.
  • I/O timeout degradation: The path is degraded due to I/O timeout.
  • High latency degradation: The path is degraded due to high latency.
  • Disable: The path is disabled.

None

Check State

State check of a path. Possible values are as follows:
  • Checking: The path is being checked.
  • Waiting: The path is waiting to be checked.
  • Succeed: The path status check succeeded.
  • Fail: The path status check failed.
  • Ignore: The path status check is ignored.
  • --: The path is not checked.

None
