You can manually monitor Exadata Infiniband switches.
- You can checks for failed switch hardware sensors
- Note. If you want to manual monitoring is your switches software version prior to 1.1.3
first make ssh root@ib
root@ib’s password:
then write
[root@ib ]# showunhealthy
OK – No unhealthy sensors
then check the power
[root@ib]# checkpower
PSU 0 present status: OK
PSU 1 present status: OK
If you use Oracle Enterprise manager grid control then
go to InfiniBand switch home page and check the status and availibility.
– How can you Monitoring the InfiniBand Switch Ports
# ibqueryerrors.pl –s RcvSwRelayErrors,RcvRemotePhysErrors,XmtDiscards,
XmtConstraintErrors,RcvConstraintErrors,ExcBufOverrunErrors,VL15Dropped
also you can
# ibstatus
# perfquery
# ifconfig
# ping Remote InfiniBand Hostname
# ibswitches
And use
verify-topology to check the Network Topology
# /opt/oracle.SupportTools/ibdiagtools/verify-topology
