SAN discovery overview
3
For a Fabric OS fabric, the seed switch must be the primary Fabric Configuration Server (FCS). If
you use a non-primary FCS to discover the fabric, the Management application displays an error
and will not allow the discovery to proceed. If the Management application has already discovered
the fabric, but afterward you create the FCS policy and the seed switch is not a primary FCS, an
event is generated during the next poll.
The Management application cannot discover a fabric that is in the process of actively configuring
to form a fabric. Wait until the fabric is formed and stable, then re-attempt the fabric discovery.
After fabric discovery successfully completes, all clients are updated to display the newly
discovered fabric.
During fabric discovery, you can define an IPv4 address or IPv6 address for the device; however,
the Management application uses the preferred IP format to connect with the device. To configure
the preferred IP format, refer to
“Configuring the preferred IP format”
NOTE
Professional edition can discover only 1 fabric.
NOTE
Professional Plus edition can discover up to 2,560 ports.
NOTE
Once a fabric is discovered an enclosure is formed for the Host having FDMI with symbolic name
enabled.When FDMI name is same for the adapters (HBA and CNA) which are displayed through
fabric discovery, auto enclosure will be displayed for the fabric/fabrics
NOTE
Professional Plus edition can discover, but not manage the Backbone chassis.Use the device’s
Element Manager, which can be launched from the Connectivity Map, to manage the device. This
device cannot be used as a Seed switch.
FCS policy and seed switches
The Management application requires that the seed switch is the primary Fabric Configuration
Server (FCS) switch at the time of discovery.
Setting time on the fabric will set the time on the primary FCS switch, which will then distribute the
changes to other switches.
When FCS Policy is defined, ConfigDownload is allowed only from the primary FCS switch, but
Management application does not check at the time of download that the switch is the primary FCS
Switch.
NOTE
Switches running in Access Gateway mode cannot be used as the seed switch.
NOTE
The Backbone Chassis cannot be used as seed switch to discover and manage edge fabrics. You
must discover a seed switch from each edge fabric to discover and manage the edge fabric.
