Performing manual mapping

Perform the following steps to do manual mapping:

  1. Open the Manual Mapping view. To do so, click Manual Mapping or click the arrow beside Manual Mapping (by default the third button from the left). This opens a list of choices. Figure 1 shows this list.
    Figure 1. Manual Mapping button in group
    This picture shows Manual Mapping available.
    I/O -> Hardware
    Displays the Manual Mapping view in the I/O > Hardware format. You probably use this format less frequently than the Hardware > I/O format. In this chapter, you use the Hardware > I/O format.
    Hardware -> I/O
    Displays the Manual Mapping view in the Hardware > I/O format. This is the more commonly used format. This format is the default (unless you change it).

    The Hardware > I/O format is also displayed if you clicking Manual Mapping (and have not changed the default).

    The rest of the steps are based on the Hardware >I/O format of the Manual Mapping view.

    You perform manual mapping mainly in the Hardware pane and the I/O Config pane of the Manual Mapping view. Figure 2 shows these panes.

  2. Select the target row containing the PCHID to which you want to map one or more CHPIDS. Figure 2 shows the CHPIDs in the I/O Config pane.
    Note:
    1. The tool displays only compatible CHPID types in the I/O Config pane.
    2. If the CHPID column is blank, no selections are available in the I/O Config pane. Figure 3 shows an example:
      Figure 3. CHPID column is blank - no selections in I/O Config
      This picture shows Manual Mapping available.
  3. Map one or more CHPIDs to the PCHID by selecting one or more check boxes in the first column of the I/O Config pane.
    • If you map a single CHPID to the selected PCHID, the tool inserts a check mark in the selected check box. The tool also makes the following changes:
      • In the Hardware pane, in the CHPID column, the tool inserts the CHPID number.
      • In the Hardware pane, in the Assigned By column, the tool inserts the value Manual.
      • In the I/O Config pane, in the Assigned By column, the tool inserts the value Manual.

      Figure 4 shows these changes.

      Figure 4. Selecting a check box to map a single CHPID to a PCHID
      This picture shows Manual Mapping available.
      Note:
      1. If you map a single CHPID to a PCHID, the tool might automatically map an additional CHPID to that PCHID. Figure 5 shows an example. The user selected the check box (at 0.F1) in row three of the I/O Config pane, and the tool selected the check box (at 0.F1) in the ninth row as well.
        Figure 5. CHPID Mapping Tool automatically maps a CHPID to a PCHID
        This picture shows Manual Mapping available.

        Notice the (S) after the value Manual in the Assigned By row in the Hardware pane. The (S) indicates the CHPID is spanned.

      2. If the I/O Config pane has a green box inside a check box, this means the CHPID is already assigned to another PCHID, and you cannot assign it to the target PCHID. Figure 6 shows an example.

      3. On some channels, you can define multiple CHPIDs. You can define up to 16 CHPIDs on one AID. OSA Express3 cards can have four ports (for two PCHIDs) or two ports (for one PCHID).
      4. If you map more than one CHPID to a PCHID (or the tool does this for you automatically), the tool makes the changes listed in Step 3 with two differences:
        • In the Hardware pane, in the first column, the tool displays a plus sign.
        • The tool inserts the value Multiple -> in the CHPID and Assigned By columns.

          Figure 7 shows an example of these differences.

          Figure 7. Plus sign in first column and "Multiple -> in CHPID and Assigned By columns
          This picture shows Manual Mapping available.
          Clicking the plus sign expands the row. Figure 8 shows the expansion.
          Figure 8. Expanding the information in the Hardware pane
          This picture shows Manual Mapping available.
          • The plus sign changes to a minus sign.
          • The expansion shows the value Manual in the CHPID and Assigned By columns.
            Note: The (S) after Manual indicates the CHPID is spanned
  4. Optionally, save your session. See Saving a session.
  5. Optionally, create another IOCP file with statements that include the assignments you have made with the tool. For details, seeExporting an IOCP input file.
