Upgrading to Fabric
OS v4.4.x
Recommended upgrade procedures to Fabric OS v4.4 include the
following:
Before loading v4.4:
• Run configupload. Creates a backup configuration, should the user
want to return to v4.2.
• Run supportShow. Captures the previous error logs in v4.2.
• Run chassisName. Changes the default factory configuration to a
more meaningful name.
After loading Fabric OS v4.4, refer to “Logging, supportFTP,” earlier in this
table.
WWN card FRU repair
If an HA failover or power cycle occurs during a FRU replacement on the
WWN card, the Core Switch 2/64 or SAN Director 2/128 is
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.
Zoning
Issue: Domain 0 in a zoning configuration file is invalid but has not been
previously enforced.
Workaround: Prior to upgrading a switch to Fabric OS v4.2.x or later,
ensure that the fabric’s zoning configuration does not contain domain ID 0,
which is used for zoning. This is specific only to v4.x switches.
Zoning
When enabling a new zone configuration, the user must ensure that the size
of the zone configuration does not exceed the minimum size supported by
all the switches in the fabric. Zone configuration sizes can be determined by
executing cfgsize on all the switches in the fabric.
