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.
25G and 40G 45000 Series Adapters Support iWARP
100G 45000 Series Adapters do not support iWARP at this time.
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.
NPAR Mode Issue
On Cisco and Lenovo servers, a known issue in NPAR mode prevents the
enumeration of the maximum functions. Use the appropriate workaround:
For Cisco servers, pass the kernel parameter
pci=realloc
during boot
time.
For Lenovo servers, use the
Enable ARI in System BIOS
option.
