Installation and Configuration 101
one of the following actions to bring the SP Switch Router Adapter card
online:
• A switch initialization
• An unfencing sequence
• Another Switch management sequence
The appropriate action depends on what state the SP system is in with
respect to the dependent node. For example, if no
Estart command has been
issued to reinitialize the SP Switch since the dependent node (the SP Switch
Router Adapter) was installed, then an
Estart command is needed. If the
dependent node was fenced from the SP Switch without the
-autojoin option,
then an
Eunfence command should suffice.
Many different states are possible. Consult
RS/6000 SP: Installation and
Migration Guide Version 2 Release 4,
GC23-3898
and
RS/6000 SP:
Administration Guide Version 2 Release 4,
GC23-3897 for descriptions of the
administrative actions needed to bring extension nodes online (dependent
nodes are specific types of extension nodes). See
RS/6000 SP: Diagnosis
and Messages Guide Version 2 Release 4,
GC23-3899 for information on
diagnosing extension node configuration problems.
The SP Switch Router Adapter media card remains in
ConfigState=FullyConfigured
,until it is brought online via a switch
initialization or unfencing sequence.
Should the SwitchNodeUp
-trap message not reach the SP SNMP Manager,
use the
grcard command to check the card’s readiness and state. The grcard
command
must
return running for the SP Switch Adapter card before the card
can be brought online.
3.15.1 Checking Connectivity to the SP System
The procedure in this section is useful when a problem is suspected with the
SP Switch Router Adapter media card, its connection to the SP Switch, or its
connection to the SP Switch Router hardware. This section is intended for
hardware service personnel, although parts may be applicable to customer
problem determination.
Before beginning this procedure, it may be helpful to verify the configuration
of the media adapter. If you are unable to find a configuration problem or are
unable to correct the configuration due to potential hardware problems, this
procedure should be used to check the connection to the SP Switch.
