Checking the Internal ServerNet X and Y Fabrics
Using TSM to Check the Internal ServerNet Fabrics
Use the Group Connectivity ServerNet Path Test action in the TSM Service
Application to check the internal ServerNet X and Y fabrics for the local system. Use
this test when you want to check the integrity of group-to-group connections along one
ServerNet fabric at a time. This test checks the following components:
•
ServerNet cables
•
PMF CRUs
•
IOMF CRUs
•
SEBs
1. Using a system console attached to the node whose internal fabric you want to
check, log on to the TSM Service Application. Logging on to the TSM Service
Application is described in detail in Appendix F, Common System Operations. The
Management Window appears.
2. In the tree pane, right-click either the Internal_ServerNet_X_Fabric or the
Internal_ServerNet_Y_Fabric and select Actions. The Actions dialog box appears.
3. From the Actions list, click Group Connectivity ServerNet Path Test.
4. Click Perform action. The Action Status window shows the progress of the action.
5. Check for an alarm on the Internal_ServerNet_X_Fabric or the
Internal_ServerNet_Y_Fabric. If no alarm is present, the action completed
successfully and ServerNet messages are able to use the fabric.
6. If an alarm is present, refer to Using TSM Alarms on page 7-12 to identify the
repair actions for the alarm.
Using SCF to Check the Internal ServerNet Fabrics
Use the SCF STATUS SERVERNET command to check processor-to-processor
connectivity for both fabrics within a system:
>SCF STATUS SERVERNET $ZSNET
