  • storage tape library path show

    Display a list of Tape Libraries on the given path

    Availability: This command is available to cluster administrators at the admin privilege level.

    Description

    This command displays path information for a tape library and has the following parameters by default:

    • Node name

    • Initiator port

    • Target port

    • TPGN (Target Port Group Number)

    • Port speeds

    • Path I/O in Kbytes/sec

    • IOPs

    Parameters

    { [-fields <fieldname>,…​]

    fields used to be used in this display

    | [-detail ]

    Using this option displays the following:

    • Target IOPs

    • Target LUNs

    • Path IOPs

    • Path errors

    • Path quality

    • Path LUNs

    • Initiator IOPs

    • Initiator LUNs

    | [-instance ] }

    If you specify the -instance parameter, the command displays detailed information about all fields.

    [-node {<nodename>|local}] - Controller name

    The name of the clustered node for which information is being displayed.

    [-array-name <array name>] - Library Name

    Name of the storage tape library that is connected to the cluster.

    [-target-wwpn <text>] - Target Port

    Target World Wide Port Name. Port on the storage tape library that is being used.

    [-initiator <text>] - Initiator Port

    Initiator port that the clustered node uses.

    [-initiator-side-switch-port <text>] - Initiator Side Switch Port

    Switch port connected to the clustered node.

    [-tpgn <integer>] - Target Port Group Number

    TPGN refers to the target port group to which the target port belongs. A target port group is a set of target ports which share the same LUN access characteristics and failover behaviors.

    [-port-speed <text>] - Port Speed

    Port Speed of the specified port.

    [-path-io-kbps <integer>] - Kbytes of I/O per second on Path(Rolling Average)

    Rolling average of Kbytes of I/O per second on the library path.

    [-path-iops <integer>] - Number of I/O per second on Path(Rolling Average)

    Rolling average of I/O per second on the library path.

    [-initiator-io-kbps <integer>] - Kbytes of I/O per second on Initiator(Rolling Average)

    Rolling average of Kbytes of I/O per second on the initiator port.

    [-initiator-iops <integer>] - Number of I/O per second on Initiator(Rolling Average)

    >Rolling average of I/O per second on the initiator port.

    [-target-io-kbps <integer>] - Kbytes of I/O per second to Target(Rolling Average)

    Rolling average of Kbytes of I/O per second on the target port.

    [-target-iops <integer>] - Number of I/O per second to Target(Rolling Average)

    Rolling average of I/O per second on the target port.

    [-target-side-switch-port <text>] - Target Side Switch Port

    Switch port connected to the tape library.

    [-path-link-errors <integer>] - Link Error count on path

    Fibre Channel link error count.

    [-path-quality <integer>] - Percentage of weighted error threshold

    A number representing the threshold of errors that is allowed on the path. Path quality is a weighted error value. When the error weight of a path exceeds the threshold, I/O is routed to a different path.

    [-path-lun-in-use-count <integer>] - Number of LUNs in the in-use state on this path

    Number of LUNs on this path.

    [-initiator-lun-in-use-count <integer>] - Number of LUNs in the in-use state on this initiator

    Number of LUNs on this initiator.

    [-target-lun-in-use-count <integer>] - Number of LUNs in the in-use state on this target

    Number of LUNs on this target.
