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
