Table 5-3
Solving Node-to-Node Communication Problems
Problem
Alternating root node panics
ServerNet I link exception
errors are reported
continued
Possible Cause
ServerNet I cross-cabled in
two-node cluster (and the CI
serial cable is not used)
ServerNet I cable is defective
SPA is defective
Action
Power down the cluster. Verify that
ServerNet I is cabled between cluster
nodes (X to X and Y to Y) as described in
Chapter 2 of this guide. Correct the
cabling and boot the cluster.
Verify that the ServerNet I cables are
properly connected, do not have bent
pins, and are not crimped or
compromised in any way. If necessary,
replace the ServerNet I cables.
ServerNet I cables can be damaged if
improperly secured or crimped when a
rack-mount server on a slide-rail is
pushed back into a rack.
Eliminate the ServerNet I cable as a
possible cause. Then, verify the SPA
functionality by using the ServerNet I
graphical monitor or the ServerNet I
command line diagnostic (spam). See
the spam(1M) man page for additional
information.
