6.2.3 Configuration view in the view frame

The view frame of the Path Management window displays one of the following two views:

This subsection explains the window components in the Configuration view. If the content displayed for each storage subsystem differs, this subsection explains the displayed contents individually.

The following figures show the Configuration view for each storage subsystem.

When using the TagmaStore USP, the display format for the following items is different from that for other storage subsystems:

If you are using Universal Storage Platform V, the Configuration view is not displayed. In the view frame, the KAPL02087-I message is displayed. The following buttons and check boxes for the Configuration view are not displayed:

The following describes each window component:

Type
In Type you can select the type of path to be displayed in the view frame. The selectable types are Owner path and Non-owner path.
  • When using the Thunder 9200, Thunder 9500V Series, or TagmaStore AMS/WMS series
    By default, both the Owner path and Non-owner path check boxes are selected.
    The Type specification has priority over the Status specification. For example, if you select only the Owner path option in Type, the Configuration view will display only the owner paths whose statuses are selected in the Status check boxes.
    When you clear the Owner path check box or Non-owner path check box, the Configuration view narrows down the displayed paths accordingly.
    Note that the Type settings remain in effect even when you click the Path List tab and switch to the Path List view.
    Owner path check box
    When you select Owner path, the Configuration view displays owner paths.
    Non-owner path check box
    When you select Non-owner path, the Configuration view displays non-owner paths.
  • When using the Lightning 9900 Series, Lightning 9900V Series, or TagmaStore USP
    In Type you can select the type of path to be displayed in the Configuration view. Since all paths are owner paths, only the Owner path check box is displayed as active.
    The Type specification has priority over the Status specification. For example, if you clear the Owner path check box in Type, the Configuration view will not display those paths even if their statuses are selected in the Status check boxes.
    Note that the Type settings of the Configuration view remain in effect even when you click the Path List tab and switch to the Path List view.
    Owner Path check box
    Select Owner path to display owner paths. Clear Owner path to hide all paths.

Status
You use the following four check boxes to select the status of the paths to be displayed. By default, all check boxes are selected.
When you clear a Status check box, the Configuration view narrows down the items displayed.
  • [Figure] Online path check box
    When you select this check box, the Configuration view displays the paths that have the Online or Online(P) status.
  • [Figure] Offline path check box
    When you select this check box, the Configuration view displays the paths that have the Offline(C) status.
  • [Figure] Offline (Error) path check box
    When you select this check box, the Configuration view displays the paths that have the Offline(E) or Offline(P) status.
  • [Figure] Online (Error) path check box
    When you select this check box, the Configuration view displays the paths that have the Online(E) or Online(EP) status.
Note that the Status settings remain in effect even when you click the Path List tab and switch to the Path List view.

Online button
Clicking this button changes the status of a selected path (or paths) to Online.
When no path is displayed in the Configuration view, or all the paths displayed in the Configuration view are in the Online status and no path is selected, the Online button is displayed as inactive.
If you click this button without first selecting a path, the Configuration view changes the status of all paths that are not already Online to Online.
If you attempt to change the status of multiple paths to Online but the status of one of those paths cannot be changed, the message KAPL02022-W appears. To ignore the path whose status cannot be changed and to continue processing, click the OK button. To stop processing, click the Cancel button.

Offline button
Clicking this button changes the status of a selected path (or paths) to Offline(C).
In a cluster configuration, if a user selects a path whose status is Online and clicks the Offline button during reserve processing, the status of the selected path switches to Online(P), which indicates that the offline processing is in a waiting-to-execute state. Despite this change in status, however, the appearance of the line that indicates the path status does not change. After the reserve processing finishes and the offline processing executes, the path status will switch to Offline(C); however, the path information displayed in the Configuration view will not be automatically updated. To display the most recent path status, click the Refresh button.
When no path is displayed in the Configuration view, or no path is selected, the Offline button is displayed as inactive.
If you attempt to change the status of multiple paths to Offline(C) but one of those paths cannot be changed, the message KAPL02023-W appears. To ignore the path whose status cannot be changed and to continue processing, click the OK button. To stop processing, click the Cancel button.

Host
host is displayed.

HBA port button
Displays the HBA port number as the host port number (hexadecimal) converted into decimal.
The HBA ports that are actually connected are usually displayed as active. If, however, the Type or Status check box specifies that a connected path is not to be displayed, the HBA port button is displayed as inactive.
Placing the mouse pointer over an HBA port button displays a tool tip containing the HBA port number.
Clicking an HBA port button displayed as active selects all the paths connected to that clicked HBA port.

Note
The paths are not displayed in the Configuration view when they are connected to an HBA port whose HBA port number is 16 or higher. To view or operate these paths, use the Path List view. For details about the Path List view, see 6.2.4 Path List view in the view frame.

Paths
The paths that meet the conditions selected in the Type and Status check boxes are displayed. Lines are used to indicate the paths connecting a host and storage subsystem. Table 6-5 Appearance of lines that indicate paths, and the path status shows the appearance of lines that indicate paths, and the corresponding path status.
Placing the mouse pointer over a path displays a tool tip giving the path status (Online, Offline(C), Offline(E), Offline(E) (intermittent error), Online(E), or Online(E) (intermittent error)) and whether the path is an owner path or non-owner path.
When you click any of the following window components and select a path, the line is displayed thicker than before:
  • Line that indicates a path
  • HBA port button
  • CHA port button
  • CHA button

    Table 6-5 Appearance of lines that indicate paths, and the path status

    Lines that indicate paths Path status
    [Figure] (Black unbroken line) Online or Online(P)
    [Figure] (Black broken line) Offline(C)
    [Figure] (Red broken line)# Offline(E) or Offline(P)
    [Figure] (Red unbroken line)# Online(E) or Online(EP)
    When the LU dynamic deletion functionality is used, the path whose status is Online(E) is deleted. Therefore it is not displayed.

    #
    If the intermittent error monitoring functionality is enabled, the line that indicates the error path flashes when an intermittent error occurs in the path (The line lights for 3 seconds and then goes out for 0.2 seconds, repeatedly).

  • When using TagmaStore USP
    When you display the CHA port in the minimized mode, one of the paths that has the most impact on the system is displayed when multiple paths connect to the CHA. The displayed paths are sorted in the following order of path status values:
    1. Online(E) (intermittent error)
    2. Online(E) or Online(EP)
    3. Offline(E) (intermittent error)
    4. Offline(E) or Offline(P)
    5. Offline(C)
    6. Online or Online(P)

CHA port button
These buttons display the CHA port number.
  • When using the Thunder 9200, Thunder 9500V Series, or TagmaStore AMS/WMS series
    The buttons for the channel adapter ports that are actually connected are usually displayed as active. If, however, the Type or Status check box specifies that a connected path is not to be displayed, the CHA port button is displayed as inactive.
    Clicking a button displayed as active selects all the paths connected to that clicked channel adapter port.
    When using the Thunder 9200, Thunder 9500V Series (except the Thunder 9580V), or TagmaStore AMS/WMS (except the TagmaStore AMS 1000) series two CHA port buttons are displayed per CHA button.
    When using the Thunder 9580V or the TagmaStore AMS 1000, four CHA port buttons are displayed per CHA button.
  • When using the Lightning 9900 Series, or Lightning 9900V Series
    These buttons display the channel adapter port number. The buttons for the channel adapter ports that are actually connected are usually displayed as active. If, however, the Type or Status check box specifies that a connected path is not to be displayed, the CHA port button is displayed as inactive.
    Clicking a button displayed as active will select all the paths connected to that channel adapter port.
    When using the Lightning 9900 Series, four of these buttons are displayed for each CHA button. When using the Lightning 9900V Series, eight of these buttons are displayed for each CHA button.
    Placing the mouse pointer over these buttons displays a tool tip containing the channel adapter port number.
    For the Lightning 9900V Series, the tool tips for the buttons a to r of CL1 may display 3a to 3r, and the tool tips for the buttons a to r of CL2 may display 4a to 4r.
  • When using TagmaStore USP
    This button displays the CHA port number. The CHA port button is displayed in the minimized or the expanded mode for each CHA. Clicking the Minimize button or the Expand button switches the mode for displaying the CHA ports. The following explains the displays in the minimized mode and expanded mode.

  • Display in the minimized mode
    All the CHA ports belonging to a CHA (for example, CHA-1E) are integrated and displayed as one label. The button displays the first CHA port number and the last CHA port number, connected by a hyphen (-). For example, when a CHA contains CHA ports from 1A to 7D, the CHA port button shows 1A-7D.
    If the connected paths are disabled by selecting the Type or Status check boxes, the CHA port button will also be disabled.
    You cannot select a path by clicking an active CHA port button.
  • Display in the expanded mode
    Each CHA port belonging to a CHA (for example, CHA-1E) is displayed in a button independently.
    If the connected paths are disabled by selecting the Type or Status check boxes, the corresponding CHA port button will also be disabled.
    Clicking an active button selects all paths connected to the selected CHA port.

Expand button and Minimize button
These buttons are displayed only when using TagmaStore USP. The buttons switch the mode for displaying the CHA ports of each CHA.
  • Expand button ([Figure])
    The Expand button appears when the CHA ports are displayed in the minimized mode. When you click this button, it changes to the Minimize button and all the CHA port numbers belonging to the selected CHA appears. When you place the mouse pointer on the Expand button, Expand is displayed in the tool tip.
  • Minimize button ([Figure])
    The Minimize button appears when the CHA ports are displayed in the expanded mode. When you click this button, it changes to the Expand button and one CHA port number that integrates all the CHA ports belonging to the selected CHA appears.
    When you place the mouse pointer on the Minimize button, Minimize is displayed in the tool tip.
When there is already a CHA port in the expanded mode and you switch another CHA port to the expanded mode, the first CHA port in the expanded mode is switched to the minimized mode. Only one CHA can be in the expanded mode.
The Expand or Minimize button is always active, whether or not the path connected to the CHA is displayed.

CHA button
This button indicates a channel adapter.
  • When using the Thunder 9200, Thunder 9500V Series, or TagmaStore AMS/WMS series
    There are two buttons: CHA0 and CHA1. If one or more of the channel adapter ports belonging to a CHA are displayed as active, the corresponding CHA button is displayed as active.
    If you selected an LU in the tree frame, HDLM displays whether the paths connected to the CHA are owner paths or non-owner paths based on the information of the paths connected to the LU. For example, when the path connected to CHA0 is an owner path, the CHA0 button displays CHA0 (Owner Path). When the path connected to CHA0 is a non-owner path, the CHA0 button displays CHA0 (Non-owner Path).
    If you selected a storage subsystem in the tree frame, owner paths and non-owner paths are not distinguished so the label on the button remains CHA0 or CHA1 without change.
    Clicking a button displayed as active selects all the paths connected to the port that belongs to that clicked channel adapter.
  • When using the Lightning 9900 Series, or Lightning 9900V Series
    The owner and non-owner paths are not distinguished, so no number is attached to CHA.
    If one or more of the channel adapter ports belonging to CHA are displayed as active, the CHA button is displayed as active.
    Clicking CHA selects all paths connected to the ports belonging to that channel adapter.
  • When using TagmaStore USP
    A number is used to identify the cluster and channel adapter. The button displays the first CHA port number and the last CHA port number, connected by a hyphen (-). The channel adapter ports connected to the channel adapter are displayed as active when one or more is active. When clicked, all paths connected to ports belonging to the channel adapter are selected.

CL 1
This area is displayed only when using the Lightning 9900 series, Lightning 9900V series, or TagmaStore USP. This area displays the cluster number (CL 1) of the RAID device.

CL 2
This area is displayed only when using the Lightning 9900 series, Lightning 9900V series, or TagmaStore USP. This area displays the cluster number (CL 2) of the RAID device.

LU
If you selected a storage subsystem in the tree frame, the box next to LU displays the number of LUs that can be accessed from the host and storage subsystem.
If you selected an LU in the tree frame, the box next to LU displays the LU number.

Subsystem
This box displays the name of the storage subsystem that you selected in the tree frame. A storage subsystem name consists of the following three elements, separated by periods:
  • Vendor ID: the name of the storage subsystem vendor (for example, HITACHI)
  • Model ID: indicates the model name of the storage subsystem (for example, 9200 indicates the Thunder 9200)
  • Serial number: the serial number of the storage subsystem (for example, 0123)
Table 6-6 Model IDs and the model names of corresponding storage subsystems shows the model IDs displayed in the Configuration view, and the model names of corresponding storage subsystems supported by HDLM.
