Resume monitoring of discovered switches
NOTE
Monitoring is not supported on Hosts.
NOTE
You can only monitor a switch that is reachable and has valid credentials.
To monitor a switch, complete the following steps.
1. Select Discovery > Fabrics.
The Discover Fabrics dialog box displays.
2. Select one or more switches that you want to monitor from the Discovered Fabrics table.
3. Click Monitor.
The Monitor Status dialog box displays with the status.
4. Click Close on the Monitor Status dialog box.
5. Click Close on the Discover Fabrics dialog box.
SAN Seed switch
The seed switch must be running a supported Fabric OS 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 version in the fabric.
