SAN Director 2/128 Fabric OS 4.2.x Release Notes
The SAN Director 2/128 can be configured only as a single domain, as
opposed to two logical domains in the Core Switch 2/64. In other words,
all port blades and slots are a part of that single switch.
If an HA failover or power cycle occurs during a FRU replacement on the
WWN card, the SAN Director 2/128 becomes nonoperational.
CAUTION: When performing a FRU replacement on a WWN card,
complete the FRU procedure before attempting an HA failover or power
cycling the chassis.
To use zoning in a non-RCS (reliable commit service) mode fabric (that is, in
a fabric containing switches with firmware versions other than v2.6.x, v3.1,
and v4.1), HP recommends that all appropriate zoning licenses be installed
on all the switches in the fabric before attempting to bring a switch in to the
fabric.
If the zoning license is to be removed, the user must make sure it is
reinstalled properly on the affected switch before attempting the
cfgenable zoning operation.
Failure to follow these steps can cause inconsistency of zoning configuration
on the affected switches if a zoning operation is attempted from a remote
switch in the fabric. On the affected switches, an error message appears on
the console or Telnet session (or by issuing the errShow or errDump
command), indicating that the zoning license is missing.
Domain 0 in a zoning configuration file is invalid but was not previously
enforced.
Workaround: Prior to upgrading a switch to Fabric OS v4.2.x, ensure that
the fabric's zoning configuration does not contain domain ID 0, which is
used for zoning. This is specific only to 4.x switches.
