haShow

Use the haShow command to display the control processor (CP) status. The display includes the following information:

  • Local CP state (slot number and CP ID), warm or cold, recovering or recovered.
  • Remote CP state (slot number and CP ID).
  • High Availability (enabled or disabled).
  • Heartbeat (up or down).
  • Health of standby CP.
  • HA synchronization status.
The following is an example of haShow output:
chassisX8:admin> hashow
Local CP (Slot 5, CP0): Active, Cold Recovered
Remote CP (Slot 6, CP1): Non-Redundant

The following observations can be made about this command output:

  • A warm recovery typically does not disrupt traffic flow.
  • A cold recovery is usually a result of a reboot of the active CP, which disrupts traffic.
  • A lack of HA synchronization can be related to a firmware download in progress or that the device is recovering from a reboot or power-cycle.
