Feature Constraints
This appendix provides information about feature constraints implemented in the
current release.
These feature coexistence constraints will be removed in the next release and
customers can 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
The current release does not support configuration of both FCoE and iSCSI on
PFs belonging to the same physical port. Either FCoE or iSCSI is allowed on a
physical port.
After a PF with either iSCSI or FCoE personality has been configured on a port
using either HII or 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 QLogic management tools is written in NVRAM
configuration. When this limitation is removed, users can configure additional PFs
on the same port for storage.
Concurrent RoCE and iWARP Is Not Supported on the Same Port
RoCE and iWARP are not supported on the same port. HII and QLogic
management tools do not allow users to configure both concurrently.
NPAR Configuration Is Not Supported if SR-IOV Is Already Configured
If SR-IOV is already configured, NPAR configuration is not allowed unless SR-IOV
is first disabled.
NPAR is configured using either HII or QLogic management tools. When
NPAR is enabled, device- and adapter-level configuration for multiple PCIe
functions are enumerated on all ports of the adapter.
SR-IOV is configured using either HII or QLogic management tools. When
SR-IOV is enabled, adapter-level configuration is not allowed if NPAR is
already configured.
For the HII mapping specification, the
Virtualization Mode
field supports
only the values
None
,
NPAR
, and
SR-IOV
. The value
NPARSRIOV
is not
currently supported.
