HP FlexFabric Virtual Switch 5900v Troubleshooting Guide

Problems with EVB

VSIs cannot get online after the EVB port on the

physical switch is manually brought up

Symptom

Enable EVB on the port or aggregate interface connecting the physical switch to the ESXi host. After the

VSIs have been registered on the VM, shut down the port or aggregate interface on the physical switch

by using the shutdown command. When the VSIs time out and get offline, one of the following failures

occurs:

• Bring up the port on the physical switch, and only some VSIs can get online.

• Bring up the aggregate interface on the physical switch, and no registered VSIs can get online.

Solution

By default, STP is enabled on the physical switch port. When the port state changes from down to up, the

port performs STP negotiation with the remote port. The physical network card interface on the ESXi host

does not support STP, so the negotiation fails. During the negotiation period, the STP port is in discarding

state and does not accept user packets, so the VSIs on the VM cannot be registered.

To resolve the problem:

1. Configure the port or aggregate interface connecting the physical switch to the ESXi host as an STP

edge port by executing the

stp edged-port command in Layer 2 Ethernet interface view or Layer 2

aggregate interface view.

2. If the problem persists, contact HP Support.

The VSI gets offline when you migrate the storages

of two VMs at the same time

Symptom

1. Bind the vNICs of two VMs to a port group.

2. After the VSI gets online, migrate the storages of the two VMs at the same time.

The VSI gets offline.

Solution

To resolve the problem:

1. Migrate the VMs one by one.
