Monitoring DSPU Resources

DSPU is a Cisco IOS software feature that enables a Cisco router to act as a downstream physical unit (DSPU) concentrator in SNA networks. This feature eliminates the need for an SNA gateway to provide PU concentration. This support also reduces the number of PU definitions required in the mainframe, which conserves mainframe resources, simplifies administration, and reduces polling overhead.

ISM adds routers as DSPU concentrators through the Discovery feature. You can monitor these DSPU concentrators in ISM from SOLVE:Netmaster. ISM administrators can change and delete DSPU resources. You can also access a list of Cisco IOS software show commands that you can issue to a specific DSPU concentrator from ISM.

This chapter describes the following tasks to help you find information about DSPU concentrators:

Displaying a List of Routers Defined as DSPU Concentrators

From the ISM : DSPU Router List panel, you can obtain the following information about a DSPU concentrator:

List of logical units (LUs) associated with a specific DSPU concentrator and the status of each LU
Peer PUs and peer LUs associated with a specific DSPU concentrator

Complete the following tasks to display a list of DSPU concentrators being monitored by ISM:

Step 1 On the ISM : Monitoring Menu panel, type D in the Select Option field and press Enter. The ISM : DSPU Router List panel is displayed (Figure 8-1).

Figure 8-1: ISM : DSPU Router List Panel

Step 2 To view further DSPU details, do one of the following on the ISM : DSPU Router List panel:

To display a list of DSPUs, type S next to a service point name and press Enter (see the "Viewing DSPUs and Associated LUs and PUs" section).
To display a list of host names, type H next to a service point name and press Enter (see the "Viewing Host Names and Associated LUs and PUs" section).

Viewing DSPUs and Associated LUs and PUs

To view LUs and PUs associated with a specific DSPU, perform the following steps:

Step 1 On the ISM : DSPU Router Selection List panel, type S next to a service point name and press Enter. The ISM : DSPU List for Router panel (Figure 8-2) is displayed for the selected router.

Figure 8-2: ISM : DSPU List for Router Panel

Step 2 To view LU details for a DSPU, on the ISM : DSPU List for Router panel type L next to the DSPU name and press Enter. The ISM : LU Details for DSPU panel (Figure 8-3) is displayed for the selected DSPU.

For information about the LU details on this panel, press F1 for help.

Viewing Host Names and Associated LUs and PUs

To view LUs and PUs associated with a specific DSPU, perform the following steps:

Step 1 On the ISM : DSPU Router List panel, type H next to a service point name and press Enter. The ISM : Host List for DSPU panel (Figure 8-5) is displayed for the selected router.

Figure 8-5: ISM : Host List for Router Panel

Step 2 To view LU details for a host, on the ISM : Host List for Router panel type L next to the host name and press Enter. The ISM : LU Details for Host panel (Figure 8-6) is displayed for the selected DSPU.

For information about the LU details on this panel, press F1 for help.

Obtaining Additional Information About DSPUs

The ISM DSPU Monitoring function provides standard Cisco IOS software show commands that you can use to obtain additional information about a DSPU resource that is useful for monitoring and problem determination purposes.

Complete the following steps to obtain additional information about a DSPU resource:

Step 1 From the ISM : Router List panel, type CI next to a service point name and press Enter. The ISM : Command Interface panel (Figure 8-8) is displayed.

Step 2 On the ISM : Command Interface panel (Figure 8-8), type a DSPU show command in the Command field and press Enter. ISM executes the command and displays the command output on the ISM : Command Interface panel.

Figure 8-8: ISM : Command Interface Panel

The following commands are available for DSPUs:

show dspu---Displays the status of the DSPU feature.

show dspu pool xxxx---Displays the status of a specific pool of LUs. Specify the pool name in the provided field before selecting this command.

show dspu pool xxxx all---Displays a detailed status of a specific pool of LUs. Specify the name of the pool in the field to the right of the command before selecting this action.

show dspu pu xxxx---Displays the status of a specific PU. Specify the PU-name or DSPU host name in the field to the right of the command before selecting this action.

show dspu pu xxxx all---Displays a detailed status of a specific PU. Specify the PU name or DSPU host name in the field to the right of this command before selecting this action.
