When creating your BOFM configuration
file, it is best practice to avoid address duplication.
Attention: Duplication of MAC addresses can cause
serious issues with your network. Fibre Channel address duplication
can lead to data corruption, if more than one blade is trying to access
the same volume at the same time.
To ignore the duplicated
addresses and apply the configuration anyway, click Ignore.
To avoid the address duplication check, you can also select the Ignore
duplicate virtual addresses in the configuration file advanced
option on the Apply a Configuration window.
To
avoid duplicate addresses, the AMM performs the following actions:
- When a new configuration file is applied, the AMM verifies that
it does not contain internal duplicate addresses.
- Before applying the configuration, the AMM verifies that the blades
that are about to be re-configured are powered off. This ensures that
no addresses are currently in use.
- Before writing the new BOFM configuration
to the blades, the AMM disables the BOFM configuration
on all the blades that are about to be re-configured. As a result,
there can be no address duplication even if the operation has not
completed.
For flexibility, the user can override these checks and apply
the configuration even if the AMM generates warnings that duplicate
addresses might exist. In addition, if the user defines the same address,
in two different configuration files, for two chassis that are on
the same network, then the AMM can not protect against address duplication.
To
avoid address duplication, it is best practice to use a single configuration
file for a single network domain and not use the options to override
the protection that the AMM provides.
