port, Source Device, and Destination Device or ISL, if the Destination Device is located on
another switch. The ASIC port groups are 0- 1 5, 16-31, 32-47, 48-63, and 64-79. The routes
will be broken if the port mirror resources are spread across multiple port groups.
Port Mirroring is not supported on a switch with the VF feature enabled.
10 G interoperability
10 G interop between HP StorageWorks SAN Director 6 Port 10 Gb FC blade and McDATA
blades is not supported due to a hardware limitation. However, the SAN Director 6 Port 10 Gb
FC blade is supported in a chassis running in interopmode 2 or 3 (SAN Director 6 Port 10 Gb FC
blade to SAN Director 6 Port 10 Gb FC blade connections only). A SAN Director 6 Port 10-Gb
FC blade will not synchronize with a McDATA 10 G blade, but will not negatively impact the
system.
Zoning
Beginning with Fabric OS 6.2.0, all WWNs containing uppercase characters are automatically
converted to lowercase when associated with a zone alias and stored as part of a saved
configuration on a switch. For example, a WWN entered as either AA.BB.CC.DD.EE.FF.GG.HH
or aa.bb.cc.dd.ee.ff.gg.hh when associated with a zone alias will be stored as
aa.bb.cc.dd.ee.ff.gg.hh on a switch operating with Fabric OS 6.2.0 or later.
This behavioral change in saved zone alias WWN members does not impact most environments.
However, in a scenario where a switch with a zone alias WWN member with uppercase characters
(saved on the switch with pre-Fabric OS 6.2.0 code) is merged with a switch with the same alias
member WWN in lower case characters, the merge fails, because the switches do not recognize
these zoning configurations as being the same. For more information and workaround solutions,
see the latest Fabric OS Administrator Guide.
Fabric Watch
Core Blade status reporting modification
Fabric Watch has been modified so that Core blade status reporting matches CP blade reporting,
rather than status reported by port blades.

NOTE: If any type of blade goes to a faulty state, the switch/blade state will be marginal.
Port Fencing
When the Port Fencing trigger threshold is exceeded for ITW, LR, 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 of approximately 6 seconds) is always ignored to account for
expected link transition errors. The port is disabled only upon detection of a second set of
