PowerPath Installation
• PROBLEM: PowerPath installation fails.
–CAUSE: Unknown installation error.
– RESOLUTION: Reboot the system on which the PowerPath installation
fails.
NIC Teaming
• PROBLEM: Broadcom NIC teaming fails.
–
CAUSE: The following steps may result in a NIC teaming failure:
• One of the Broadcom NICs that was used in the NIC teaming
fails or is disabled. Due to the availability of the second NIC, the
private network is still active on this node through the second
NIC.
• When the first NIC is still down or disabled, the second NIC in
the teaming also fails or is disabled. This failure causes the private
network to go down completely on this node. The private IP
address on this node cannot be pinged.
• When the second NIC that failed or was disabled becomes
enabled, the private network of this node remains inactive.
NOTE: A private network becomes inactive only if the failed second NIC
becomes enabled. If the first failed NIC becomes enabled, the private network
becomes active.
– RESOLUTION: The most likely cause of this issue is a Spanning Tree
Protocol on your switch. If this issue is caused by a Spanning Tree
Protocol, perform one of the following procedures:
• Turn off
Spanning Tree on the switch.
•Enable
Port Fast Learning (or equivalent, which may be called
something different depending on the brand of switch) on the
ports of the switch to which your teamed NICs are attached.
• Use Broadcom’s LiveLink feature by right-clicking the team,
choosing
Enable LiveLink , and following the instructions in the
window.
