1. Can ping the Storage Node from the
Management Node but cannot ping the
Cluster Nodes
2. Can ping the Cluster Nodes from the
Management Node but cannot ping the
Storage Nodes
3. Cannot ping either the Storage Nodes or
the Cluster Nodes.
4. Cannot ping the Cluster Nodes in one of
the expansion cabinets.
If following the steps in Table 11 on page 60 did not correct the problem, continue
with the steps shown in "Cluster with one network".
Cluster with one network
Ping failure on one or some nodes: If one or more nodes experience a ping
failure, it indicates a problem with the node hardware or software.
1. Attempt to telnet to the node via the serial console or KVM and verify the
node is operational.
a. If telnet succeeds, check the syslog for errors.
1) If there are errors, go to"Isolating software problems" on page 69 and
continue with the steps shown there.
2) If there are no errors, it indicates a network problem. Go to Table 12 and
continue with the steps shown there.
b. If telnet fails, it indicates a node hardware problem. Go to "Isolating
hardware problems" on page 63 for problem resolution.
Ping failure on all nodes: If all nodes experience a ping failure, it indicates a
problem on one of the following:
v Network. Go toTable 12 and continue with the steps shown there.
v Network adapter on the Management Node.
v DHCP configuration
v Network configuration
v Cisco blade failure
Table 12. Network troubleshooting for a cluster with one network
Symptom
1. Verify links between the Management
Node, Storage Nodes, Cisco 3550, 3500,
and 400x switches.
2. Reboot the Management Node and press
F1 to enter SETUP. Verify that Ethernet
devices are turned on.
3. Verify correct driver level for 1GB fibre
Ethernet. Verify status using the ifconfig
command.
4. Verify the correct level of the driver is
installed for the 1 GB fibre ethernet
5. Check the Cisco (3500,4003, or 4006)
switch for green status lights or system
and status LEDs. If the green lights are
on the switch is OK.
6. Verify 1 GB fibre ethernet connections
are good by swapping a known good
cable to isolate the failing device.
7. Replace the failing fibre cable, GBIC, or
network interface card.
