Benefit / Impact:
cables require proper connections for optimal efficiency. Verifying the
Ethernet cable connection quality helps to ensure that the Ethernet network

is minimal impact to verify Ethernet cable connection quality.
cables that are not properly connected may negotiate to a lower speed, work
intermittently, or fail.
Action / Repair:
the following command as the root userid on all database and storage servers:
for cable in `ls
/sys/class/net | grep ^eth`; do printf "$cable: "; cat
output should look similar to:
/sys/class/net/eth1/carrier: Invalid argument
/sys/class/net/eth2/carrier: Invalid argument
/sys/class/net/eth3/carrier: Invalid argument
argument" usually indicates the device has not been configured and is not
in use. If a device reports "0", investigate that cable connection.
Within machine types, the output of this command will vary by customer
depending on how the customer chooses to configure the available ethernet
