The bfa_supportsave and FOS supportsave commands can provide current information for the
topology map. Also, consider using the Brocade SAN Health products to provide information on
your SAN environment, including an inventory of devices, switches, firmware versions, and SAN
fabrics, historical performance data, zoning and switch configurations, and other data. Click

•
Run appropriate diagnostic tools for storage targets.
•
Determine what has changed in the SAN. For example, if the SAN functioned without problems
before installing the adapter, then the problem is most likely in the adapter installation or
configuration, adapter hardware, or adapter driver package. Other examples of things to
investigate might be changes in the connected switch or storage system firmware, or an offline
switch.
For stand-up adapters, investigate disconnected or faulty cables between the adapter, switch,
or storage controller fiber optic ports. Check if target storage devices are correctly connected
to the switch and are turned on.

adapters).
All LEDs on adapter port flashing amber.
Use appropriate tools on storage targets to gather information such as disk, tape, and
controller model and firmware levels.
Run the bfa_supportsave BCU command on the host system and save output to a file on
your system.
This command captures all driver, internal libraries, firmware, and other information
needed to diagnose suspected system issues. You can save captured information to the
local file system and send it to support personnel for further investigation.
Run the Fabric OS supportSave command on any Brocade switch and save output. This
command collects RASLOG, TRACE, supportShow, core file, FFDC data and other support
information.
