Service processor network
This section includes troubleshooting information about service processor network
problems.
Table 17. Troubleshooting the service processor network
Symptom Action
1. The rpower —a query
command does not return
with the status of all nodes
2. Cannot see all the nodes
when managing remote
Advanced System
Management (ASM)
service processors.
3. Cannot connect to
individual Remote
Supervisor Adapter (RSA)
cards using browser.
1. Check the physical connections on the RS485 network
and check for errors.
2. From the management node, use the Web browser
and try to connect to the failing node through that
node’s RSA card.
3. Check that the RSA network is properly terminated.
When more than one node is connected, terminators
should be plugged into the empty port on the dongle
and in the second RS485 port of the last node in the
chain.
4. Swap the internodal Cat 5 cable on the unresponsive
node with a known good cable. Also, replace the
dongle if a problem is suspected.
5. Swap the KVM/RS485 cable (on the xSeries 335 only)
with a known good cable. Also, replace the dongle if a
problem is suspected.
6. Review the RSA configurations and IP settings with
support.
7. Check the 10/100 Ethernet link between the RSA card
and the Cisco 3550 or 400x switch.
8. Flash the ASM service processors to the latest
firmware level.
9. Flash the RSA to the latest firmware level.
10. Check RSA configurations using the firmware update
diskette.
If following the steps in Table 17 did not correct the problem, continue with the
steps shown in “Remote Supervisor Adapter card connection failure.”
Remote Supervisor Adapter card connection failure
Use the following information to resolve Remote Supervisor Adapter card
connection failures:
1. To make sure the node has power, type:
rpower query
.
a. If the node has power,
ping
the Remote Supervisor Adapter (RSA) card
using the
HWControlPoint
field in the
lsnode
output.
1) If
ping
succeeds, reset the RSA card. If the adapter connection
continues to fail after it has been reset contact IBM support.
2) If the
ping
fails, check the network connection.
b. If the node does not have power, check the power connections.
2. If the network connection LED is lit for the RSA adapter at the Ethernet switch,
go to “Resetting the Remote Supervisor Adapter card” on page 50 and reset the
RSA adapter.
Node connection or command failure
If the Remote Supervisor Adapter (RSA) card connection is working, but the node
connection or commands issued to the node failed:
v
Connect to the RSA card and check the node list.
v
Check all cabling.
