Feature Constraints
This appendix provides information about feature constraints implemented in the
current release.
These feature coexistence constraints may be removed in a future release. At that
time, you should be able to use the feature combinations without any additional
configuration steps beyond what would be usually required to enable the features.
Concurrent FCoE and iSCSI Is Not Supported on the Same Port in
NPAR Mode
The current release does not support configuration of both FCoE and iSCSI on
PFs belonging to the same physical port when in NPAR Mode (concurrent FCoE
and iSCSI
is
only supported on the same port in Default Mode). Either FCoE or
iSCSI is allowed on a physical port in NPAR Mode.
After a PF with either an iSCSI or FCoE personality has been configured on a port
using either HII or Cavium QLogic management tools, configuration of the storage
protocol on another PF is disallowed by those management tools.
Because storage personality is disabled by default, only the personality that has
been configured using HII or Cavium QLogic management tools is written in
NVRAM configuration. When this limitation is removed, users can configure
additional PFs on the same port for storage in NPAR Mode.
Concurrent RoCE and iWARP Is Not Supported on the Same Port
RoCE and iWARP are not supported on the same port. HII and Cavium QLogic
management tools do not allow users to configure both concurrently.
NIC and SAN Boot to Base Is Supported Only on Select PFs
Ethernet and PXE boot are currently supported only on PF0 and PF1. In NPAR
configuration, other PFs do not support Ethernet and PXE boot.
When the
Virtualization Mode
is set to
NPAR
, non-offloaded FCoE boot is
supported on Partition 2 (PF2 and PF3) and iSCSI boot is supported on
Partition 3 (PF4 and PF5). iSCSI and FCoE boot is limited to a single target
per boot session. iSCSI boot target LUN support is limited to LUN ID 0 only.
When the
Virtualization Mode
is set to
None
or
SR-IOV
, boot from SAN is
not supported.
