TABLE 9 Alert types
Type of alert Description
Switch Status Change Generated whenever a switch changes from Healthy to Marginal or from Healthy to
Down. Note the following characteristics:
• If the reason a switch is Marginal or Down changes, but the Marginal or Down
status remains unchanged, a new alert is not generated. The original alert
remains in the Alerts view but the reason for the Marginal or Down status is
updated in the Description column.
• If the switch status changes between Marginal or Down, a new alert is not
generated. The original alert remains in the Alerts view but the new severity is
updated in the Severity column and the reason for the status change is also
updated in the Description column.
• If the switch status changes from Marginal or Down to Healthy, the original alert
remains in the Alerts view but its entry in the Resolved column automatically
changes from No to Yes.
The switch status corresponds to the switchStatusPolicyShow and
switchStatusPolicyChangeSet Fabric OS commands.
Switch Unreachable Generated whenever the Fabric Manager server is unable to reach a switch. Note the
following characteristics:
• A new alert is not generated as long as the switch remains unreachable. The
original alert remains in the Alerts view but the Last Occurrence column is
continuously updated with the latest unreachable times until the alert is
resolved.
• The alert is resolved when the Fabric Manager server is able to reach the switch,
if the switch is deleted from either the fabric or Fabric Manager, or if the fabric
the switch belongs to is deleted from Fabric Manager.
Seed switch change Generated when you try to change the seed switch. A fabric-level alert is displayed
when the seed switch is successfully changed; a fabric-level critical alert is displayed
when the seed switch change fails.
A fabric-level alert is also generated when the seed switch is not running the latest
Fabric OS version in the fabric. This might happen if:
• A switch running a newer version of Fabric OS joins the fabric.
• Firmware is upgraded on one of the existing switches in the fabric.
• Two fabrics are merged and the automatically selected seed switch is not the
switch running the latest Fabric OS version.
The alert is resolved when the seed switch firmware becomes the latest firmware
available in the fabric, either because you upgrade the firmware on the seed switch or
change the seed switch to a switch with the latest firmware version. See “Seed switch”
on page 66 for more information.
Note: If a fabric with switches running only Fabric OS 2.x or earlier is created due to
fabric segmentation, that fabric continues to be managed from Fabric Manager;
however, if a switch with a later Fabric OS version joins the fabric, an alert requesting
you to change the seed switch is not generated.
