8.7 Remove Cables from Disabled ServerNet Ports
on X-fabric
8.7 Remove Cables from Disabled ServerNet Ports on X-fabric
Looking at an enclosure you are removing, you can see where all the ServerNet cables
attach. Therefore, removing that end of the ServerNet cables is simple. However, those
cables might be attached at the other end to enclosures that are still operating. You
must be careful which ServerNet cables you remove from an enclosure that is still
operating. If you disconnect the wrong cable, you might bring down one of the
ServerNet fabrics on your system. Therefore, remove only those ServerNet cables that
are attached to an enclosure you have are removing, as follows:
1. Detach both ends of the ServerNet X-fabric cables that run between an enclosure
you have prepared and the rest of the system.
2. Using the OSM Service Connection or TSM Service Application and SCF, check
the status of the ServerNet X fabric, as described in Determine the ServerNet
Fabric Status on page A-4.
You should not normally see alarms at this point. However, if a ServerNet alarm is
generated, you might have detached a live ServerNet cable: one that does not
connect on at least one end to an enclosure that you powered off.
Repair the problem that generated the ServerNet alarm. Because problems in
ServerNet fabrics are often specific to an individual system, this guide cannot
contain every diagnostic or recovery procedure. Consult your service provider.
8.8 Reenable Disabled ServerNet Ports on both fabrics
This procedure enables the ServerNet ports that were disabled in steps 8.3 and 8.6.

Note. Consult the topology diagrams in the planning worksheets to determine which
ServerNet ports need to be reenabled. If you are unsure whether a port needs to be to
enabled, enable it anyway. Enabling an already-enabled port does not cause any problems.
