Description
All switches and Fibre Channel routers, in both edge and backbone fabrics, must
be running Fabric OS 6.1.0a or later to support this feature.
The failover policy must be enabled in all edge fabrics that are part of the traffic
isolation zones for the proper functioning of traffic isolation over FCR.
All switches must operate with Fabric OS 6.1.x or later to support this feature.
The default settings for Port Fencing reflect very low thresholds and may cause
fence ports to experience errors. HP recommends increasing these threshold values
for use in production environments. Different platforms may require different
threshold settings for optimum behavior. Port Fencing is only available with the
optional Fabric Watch license.
When the port fencing feature is enabled for ITW or CRC errors, the first set of
errors detected on an active link that meet the custom high threshold level set by
the user (or the default threshold level) is always ignored to account for expected
link transition errors. The port is disabled only upon detection of a second set of
errors, that is, the next time the user-set threshold level (or default threshold level)
is reached. This prevents a port from being disabled due to normal link transition
behaviors.
Proper behavior of Port Mirroring requires that the entire frame path contain only
8-Gb ASICs or only 4-Gb ASICs. If a frame path contains a mix of 8-Gb and 4-Gb
ASICs, this functionality will not work as intended.
When operating a switch with Fabric OS 6.1.0a, some licenses may display as
Unknown. this is due to changes in licensing requirements for some features that
no longer require a license key.
When upgrading an HP 4/256 SAN Director that has the FCIP license installed,
the licenseshow output may falsely indicate that Integrated Routing is available.
Fabric OS 6.1.1b is fully compatible with the Data Center Fabric Manager (DCFM)
management software. DCFM is a comprehensive network management application
that enables end-to-end management of HP data center fabrics. It is the next
generation product that is the successor to existing HP management products,
namely HP Fabric Manager (FM) and Enterprise Fabric Connectivity Manager
(EFCM).
DCFM is available in two versions: DCFM Professional, a complimentary
application that is ideally suited for small and medium size businesses that need
a light-weight manaement product to manage their smaller fabrics (one physical
fabric at a time, up to 1,000 ports); and DCFM Enterprise, that is designed for
enterprise-class customers and showcases unparalleled performance and scalability
(24 physical fabrics, up to 9,000 switch ports). DCFM Enterprise configures and
manges DCX backbones, along with HP StorageWorks directors, routers, switches,
and HBAs. Existing EFCM and FM customers that have active Maintenance and
Support contracts are provied a seamless migration path to DCFM Enterprise.
Table 2 on page 14 lists the earliest versions of HP software supported in this
release; these are the earliest supported software versions that interoperate. HP
recommends using the latest software versions to get the greatest benefit from the
SAN.
