Stop monitoring of a discovered fabric

NOTE

Monitoring is not supported on Hosts.

When you stop monitoring of a fabric, you stop discovery of and data collection for the specified

fabric and all associated devices.

To stop monitoring a fabric and all associated devices, complete the following steps.

1. Select Discovery > Setup.

The Discover Setup dialog box displays.

2. Select the fabric you want to stop monitoring from the Discovered Addresses table.

3. Click Unmonitor.

4. Click OK.

Seed switch

The seed switch must be running a supported Fabric OS or M-EOS version and must be

HTTP-reachable.

Sometimes, the seed switch is auto-selected, such as when a fabric segments or when two fabrics

merge. Other times, you are prompted (an event is triggered) to change the seed switch, such as in

the following cases:

• If, during fabric discovery, the Management application detects that the seed switch is not

running a supported version, you are prompted to change the seed switch.

• When one or more switches join the fabric or if the switch firmware is changed on any of the

switches in the fabric, the Management application checks to make sure that the seed switch

is still running a supported version. If it is not, then you are prompted to either upgrade the

firmware on the seed switch or to change the seed switch to a switch running a supported

firmware.

If a fabric of switches running only Fabric OS 5.X or later is created due to segmentation, the

Management application continues to monitor that fabric, but if any switch with a later Fabric OS

version joins the fabric, an event is triggered informing you that the seed switch is not running the

latest firmware and you should change to the seed switch running the highest firmware.

ATTENTION

If a seed switch is segmented or merged, historical data such as offline zone DB, profile and reports,

and Firmware Download Profile can be lost. Segmentation of a seed switch does not result in

formation of a new fabric. If a merge occurs, the historical data is lost only from the second fabric.

You can change the seed switch as long as the following conditions are met:

• The new seed switch is HTTP-reachable from the Management application.

• The new seed switch is a primary FCS.

• The new seed switch is running the latest Fabric OS or M-EOS version in the fabric.
