Switch policies Switch policies are a series of rules that define specific states for the overall switch. Fabric OS interacts with Fabric Watch using these policies. Each rule defines the number of types of errors that transitions the overall switch state into a state that is not healthy. For example, you can specify a switch policy so that if a switch has two port failures, it is considered to be in a marginal state; if it has four failures, it is in a down state. You can define these rules for a number of classes and field replaceable units, including ports, power supplies, flash memory and fans. NOTE: See Chapter 5, to view the current switch policies using the switch policy report. Interpreting event messages For information on specific error messages generated by Fabric Watch, refer to the HP StorageWorks Fabric OS 5.x diagnostic and system error messages reference guide..

Switch policies

Switch policies are a series of rules that define specific states for the overall switch. Fabric OS interacts with

Fabric Watch using these policies. Each rule defines the number of types of errors that transitions the

overall switch state into a state that is not healthy. For example, you can specify a switch policy so that if a

switch has two port failures, it is considered to be in a marginal state; if it has four failures, it is in a down

state.

You can define these rules for a number of classes and field replaceable units, including ports, power

supplies, flash memory and fans.

NOTE:

See Chapter 5, to view the current switch policies using the switch policy report.
