Table 29. Band and channel allocation chart for problem determination configuration

One of the IBM 2029 channels supports an ETR link between a server (known as

P701) and a 9037-002 Sysplex Timer. The other IBM 2029 channel that has been

provisioned uses a 4TDM card to support four ESCON links. Two of the links are

from a server to an ESCON Director, and the other two are from an ESCON

Director to control unit interfaces.

9.2 Normal operational status

It is important to understand what status is good for an IBM 2029 channel link and

attached devices, as displayed on the System Manager workstation. The initial

conditions for this network are:

• ETR ports on both the server and the 9037-002 are enabled.

• ESCON CHPIDs are online to the operating systems running in the servers.

• ESCON director ports are unblocked and have a status of online (that is, the

ports can see light on attached ESCON interface cables).

• Attached device interfaces are enabled.

• There are no outstanding IBM 2029 equipment alarms on the System

Manager workstation.

After logging in to the System Manager, the IBM 2029 System Manager window is

displayed. See Figure 131 on page 183.

Figure 131. IBM 2029 System Manager window - no active alarms

On the IBM 2029 System Manager display, information relating to only SF Hub

Band 6 and Oak Rmt Band 6 is displayed for clarity. This filtering of shelf

information is done using the following procedure:

• Click the Selected Shelves tab; the Network tree is displayed.

• Click shelf icon SF Hub Band 6; the icon is highlighted.

• Press and hold the Ctrl key and click shelf icon Oak Rmt Band 6. Both shelf

icons are highlighted.

• Click the Apply button.

• Click the Selected Shelves tab again to hide the Network tree.

• Click Surveillance, then Active Alarms to display the current active alarms

for both Band 6 shelves.

In Figure 131:

• The upper area of the IBM 2029 System Manager window is the Alarm

Banner. This shows a summary count of active alarms in the IBM 2029

network using colored fields.

• The top row of the Alarm Banner shows the number and type of alarms which

are currently active for the whole Andreas Network (all shelves).

• The bottom row of the Alarm Banner shows alarms which are currently active

for the shelves selected from the Network tree (SF Hub Band 6, Oak Rmt

Band 6).

• The alarm banner uses red, orange, and yellow to highlight the alarm counts

that have not been acknowledged.

184 Fiber Saver (2029) Implementation Guide

The alarm categories are:

• Critical (Red): A traffic-affecting anomaly that requires immediate attention.

• Major (Orange): An anomaly that may affect traffic if it does not receive

immediate attention.

• Minor (Yellow): A secondary indicator of another alarm or a condition that

does not affect traffic.

• Alerts (Light Yellow): An anomaly that is not traffic affecting; an alert can be

an early indication of equipment that is failing.

Gray indicates acknowledged alarms and alerts. Clicking a colored Alarm field

acknowledges the alarm and turns the icon gray.

• There are no active alarms of any category present in the Alarm Banner. Also,

there are no active alarms displayed in the Surveillance - Active Alarms

window.

• The Active Alarms window updates automatically when the Auto Refresh

option is selected.

To display the current physical operational state of the shelf hardware:

• Click Equipment, then Inventory.

• Either click the Refresh button or, on the menu bar, click the Refresh

pulldown, then Refresh current window.

The Equipment - Inventory window is displayed in Figure 132.
