Known Problems with this release
This section provides a list of known problems and limitations as known to HP at the time of
publication. If workarounds are available, they are included.
Defect ID: QXCR1001187596
Problem: Inconsistent behavior while deleting aggregation onVM guest for DIO interface
While deleting a DIO LACP aggregation in HPVM Guest for "iexgbe" driver a
delay may be observed in deleting an aggregation.
There is no loss of traffic, except some delay. This delay mostly attributes to two
factors
1. Low number of vCPUs
2. lan reset taking time
This issue is not very prominent if the number of interfaces in the aggregation
is lower than the number of vCPUs.
Defect ID: QXCR1001197219
Problem: When heavy UDP traffic is run over APA DIO interfaces and if network cable pull
out is performed, the UDP traffic tries to escape to other available interfaces.
As the traffic is heavy this would take the system to hang state. This behavior is
not seen with TCP traffic.
Known Problems with Switches
• HP ProCurve Switches
When disabling Cisco's Fast Ether Channel protocol on the HP 9000 server, the HP ProCurve
switches block that particular port from further use.
