Diagnosing an SIO Combo Card Network Connection Problem
$DEV_NAME $FRU_NAME, has been selected.
Before starting this service action enable the reserve cabinet(s) function.
a) Reserve the cabinet(s) for maintenance.
b) Enter a description of the service action (i.e. Diagnose an SIO combo card Gigabit Ethernet connection problem).
c) Select the estimated amount of time of the service action from the pull-down.
d) Select the Reserve button.
e) Other users will be alerted that this service action is in progress when they log in.
If the correct SIO card has been selected continue to the next step or select another SIO card from the index on the left-side of the screen.
Verify the State of the SIO combo card: $DEV_NAME - $FRU_NAME.
a) The Show Chassis screen State should be "Normal".
b) If the SIO Combo card State is NOT "Normal" check for alarms associated to this card.
c) If the SIO Combo card State is "Powered Off": Restart the SIO card.
c) If the SIO Combo card State is "Fault" proceed to the removal / replacement procedures to replace the card.
If the SIO combo card State is "Normal" and a problem still exists proceed to the next section and continue until the problem is resolved.
Verify that the remote 6920 is responding and that the links are functional.
Verify that the default gateway is reachable and responding if replicating to a different subnet.
Inspect the cable/connector for physical damage at all connection points.
Reseat the cable/connector at both ends of the link.
If necessary use the available network diagnostic tools for further isolation.
Display the SIO combo card network configuration and status to verify the following informatiom.
a) Verify the replication link addressing and status.
b) Verify that the netmask, port enabled, default gateway and IP address configuration values are correct.
c) Verify that the Gigabit Ethernet port values are correct.
Verify the ARP entries.
a) Verify that the correct remote host is in the ARP table: Display the ARP table.
b) Verify that the correct default gateway address is in the ARP table if the replication is occurring across subnets: Display the ARP table.
c) If any of the ARP table entries are incorrect clear the ARP table. After clearing the ARP table determine the cause of the incorrect entries. If necessary use the available network diagnostic tools for further isolation.
Display the SIO combo card network configuration to verify the login of the local 6920 to the remote 6920.
a) Verify that the remote 6920 port is enabled for replication. Note that the remote 6920 must configure it's own port for replication. If this has not been done correctly a "connection failure" may occur
b) Verify that the remote 6920 has enabled a "peer" link to the local 6920. If this has not been done correctly a "login" failure" may occur
Verify the login of the remote 6920 to the local 6920.
a) Verify that port 3260 is "enabled" at the local site firewall.
b) Verify that the remote 6920 is configured correctly and not to an incorrect port on the local 6920.
If at this point the problem still exists contact your next level of support.
After this sevice action has been completed all Alarms will need to be deleted: Delete Alarms.
a) From the left side of the screen select the "check mark" box to select all alarms.
b) Select the Delete button to delete all of the alarms.
Note: Be sure to delete any associated alarms from all other monitoring applications.
Disable the reserve cabinet(s) function.
b) Select the Release button.
