Moving ServerNet Cables to Different Ports on the
ServerNet II Switches
b. On all other nodes in the cluster, use the SCF ABORT LINE command to abort
the Expand-over-ServerNet line to the node being removed. Depending on
your service LAN, you might have to log on to each node individually to do this.
For example:
-> ABORT LINE $SC011
c. On the node being removed, bring ServerNet cluster services to a STOPPED
logical state:
-> STOP SUBSYS $ZZSCL
6. At the ServerNet II Switches, disconnect the X-fabric and Y-fabric fiber-optic cables
for the node you removed from the cluster.
7. Reconnect the cables to the unused ports, making sure that:
•
The fiber-optic cables connect to the same port number on the X and Y
ServerNet II Switches.
•
The fiber-optic cables connect to the same group of switches (X1 and Y1 or X2
and Y2).
8. Check for link alive at both ends of each cable. About 10 seconds after you
connect a cable to an unused port on the ServerNet II Switch, the green ServerNet
port LED near the PIC lights to indicate link alive. The status lights on the front
panel of the ServerNet II Switch also indicate link alive.
The ServerNet port LED at port 6 on the MSEB in group 01 lights to indicate link
alive. If a ServerNet port LED does not light after 60 seconds, disconnect and
reconnect the cable. If the cables are properly connected and one or both LEDs fail
to light, a PIC or cable might be faulty. For procedures to replace cables and switch
components, refer to Section 7, Troubleshooting and Replacement Procedures.
9. Use either the guided configuration procedure or SCF commands to add the
removed node back into the cluster:
•
To use the guided configuration procedure:
a. From the system console of the system you are adding, choose
Start>Programs>Compaq TSM>Guided Configuration
Tools>Configure ServerNet Node.
b. Click Start and log on to the system.
c. When the guided procedure prompts you:
•
Click Yes to install the server tools.
•
Click Yes to enable automatic line-handler configuration.
•
Click Yes to start the SNETMON subsystem (ServerNet cluster
services).
