After the SP Switch Router Adapter media card completes initialization, its state machine
enters the
Configured state (6). The media card sends an up-trap request to mib2d. mib2d
sends the SP Switch manager a pair of switchNodeUp and switchConfigState
( ConfigState=FullyConfigured ) trap messages.
The SP system administrator now decides which action is required to bring the IP router
interface on-line.
If the SP Switch Router Adapter was previously fenced from the switch network with the
-autojoin option, the SP SNMP Manager will automatically unfence the adapter. Otherwise,
the SP system administrator must perform one of the following actions to bring the SP Switch
Router Adapter card on-line. Possible actions include:
- a switch initialization
- an unfencing sequence
- other 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 re-initialize 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 is needed.
Many different states are possible. Consult the PSSP Installation and Migration Guide and the
PSSP Administration Guide for descriptions of the administrative actions needed to bring
extension nodes on-line (dependent nodes are specific types of extension nodes). See the PSSP
Diagnosis Guide” for information on diagnosing extension node configuration problems.
The SP Switch Router Adapter media card remains in fullyConfigured state until it is
actually brought on line 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 returns “running” if the card is
ready to be brought on-line.
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. Use the vi editor to determine whether proper or NULL parameters are set in the
/etc/grdev1.conf file. You can also use the maint 3 command to view the parameters for a
single card.
If you are unable to find a configuration problem or are unable to correct the configuration due
to potential hardware problems, the procedure should be used to check the connection to the
SP switch. Each SP Switch Router Adapter media card is considered a dependent node for the
