For a PVI vNIC connected to a VM running any OS other than RHEL
6u2, a PVI vNIC will stay in up state even if the
vNIC is actually set to down on the Oracle Fabric
Interconnect. This problem occurs if you first create the vNIC in a
PVI, then set the vNIC interface to none, set the
vNIC interface back to the PVI, then attempt to set the vNIC to
down.
After this series of events, the PVI vNIC will not be set to
down state unless the vNIC is in a RHEL 6u2
VM on an Oracle VM 3.4.1 server.

With iSCSI storage, a problem prevents the deletion of iSCSI LUNs
from the array. If you attempt to delete an iSCSI LUN from the iSCSI
array, after refreshing Oracle VM Manager the LUN will still be
displayed and the port connected to the LUN will be put into an
error state. This problem also occurs with physical NICs, so it
appears that this is a problem in Oracle VM Manager. Be aware to
explicitly delete an iSCSI LUN from Oracle VM Manager. This
requirement exists for vNICs and physical NICs alike.

A problem with Oracle VM hosts prevents passing traffic (even
pings) across a PVI vNIC if the MTU is set to 64000 on a RHEL 5u8
virtual machine. During testing, an MTU of 9138 K passed traffic in
all cases. Using a 9 K MTU on a PVI vNIC should be used.

For Oracle VM hosts, a problem in the host drivers prevents a
newly added LUN from being automatically recognized.
You can workaround this problem by issuing the xsigo-scan
-r -a command from the Oracle VM server.

If an event causes failover or restart of the OpenSM InfiniBand
subnet manager, multicast traffic is delayed for approximately seven
seconds while the failover or restart occurs.

Disks can be prevented from being displayed on a Linux host (or VM
running in an Oracle VM server). This problem manifests in either of
the following ways:
-
If LUN Masks are not configured on the Oracle Fabric
Interconnect and the vHBA is present, if you then create the
LUN and map it to storage, the disk is not automatically
displayed.
In this situation, you can work around the problem by
running a target rescan on the Oracle Fabric Interconnect
and then running the xsigo-scan -r -a
command on the Oracle VM host to make the LUN visible.
-
If LUN Masks are configured on the Oracle Fabric
Interconnect, but the vHBA is not already present. then if
you create the vHBA and attach it to storage, the disk is
not automatically displayed.
In this situation, you can work around the problem by
running a target rescan on the Oracle Fabric Interconnect
and then running the xsigo-scan -r -a
command on the Oracle VM host to make the LUN visible. Or,
in cases where the vHBA is not already present and is added
later, you will need to run the xsigo-scan -r
-a command on the Oracle VM 3.4.1 host to make
the LUN visible.
