Identifying Control Module Failures
You can identify a failure in a control module by:
•
LEDs. See Interpreting Control Module LEDs on page 3-2.
•
Messages. A message on the LCD panel (located behind the bezel), on the
console, in the event log, or in the Group Manager GUI Alarms panel
describes a control module failure.
•
Group Manager GUI and CLI output. The Member Controllers window or
the
member select show controllers
control module status
When viewed from the rear of the array and from left to right, control modules are
numbered 1 and 0. See Figure 1-2.
If a control module fails, see your PS Series support provider for a replacement.
Understanding Failover Behavior
Only one control module is active (serving network traffic) at one time. Each
control module includes a battery-backed write cache for storing recently-used
data. For redundancy, the cache on the secondary control module mirrors the data
that is stored in the cache on the active control module.
