Changes To Configuration Data; Selecting A Pid Format; Effects Of Pid Format Changes On Configurations - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Changes to configuration data

Table 96 lists various combinations of before-and-after PID formats, and indicates whether the
configuration is affected.
NOTE: After changing the fabric PID format, if the change invalidates the configuration data (see
Table 96 to determine this), do not download old (pre-PID format change) configuration files to any switch
on the fabric.

After changing the fabric PID format and verifying correct fabric operation, resave configuration data by
running the configUpload command.
Before downgrading firmware, change the PID back to supported PIDs such as Core PID. If the database is
automatically converted, save the converted database, and then download the older OS.

Selecting a PID format

All switches in a fabric must use the same PID format, so if you add a switch that uses a different PID format
to a fabric, the switch will segment from the fabric. The format you select for your fabric depends on the mix
of switches in the fabric, and to an extent on the specific releases of Fabric OS in use (for example,
Extended Edge PID format is only available in Fabric OS 3.1.2 and later, and Fabric OS 4.2.0 through
5.3.0).
If you are building a new fabric with switches running various Fabric OS versions, use Core PID format to
simplify port-to-area_ID mapping.
NOTE: Switches that are queried using outside calls should be configured using PID 1 (core PID) to ensure
that the correct port numbering is used in other management applications.
