Table 7-1 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 and 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 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 “Changing the Seed Switch” on page 4-7 for more information.
Note: If a fabric running only Fabric OS 2.x or lower switches is created due
to fabric segmentation, that fabric continues to be managed from Fabric
Manager; however, if a switch with a higher Fabric OS version joins the
fabric, an alert requesting you to change the seed switch is not generated.
