After replacing a messaging system component, check the following to verify that the component
is operating properly:
If applicable, verify that the green LED is lit continuously or blinking. If not, try reseating the
component.
From the System Manager, navigate to the Hardware Status and System Summary tabs to
confirm the component failure alert no longer appears. The status should be (Good).
Wait times for hard disks
If the hard drive is part of a volume, the following wait times apply:
Removal
Less than 3 seconds for the LED to turn off
Insert
Less than 1 second for first disk activity
Less than 15 seconds for the disk to be ready for REBUILD. The LED blinks at 1 Hz.

Removal
No indication appears because the LED is already off
Insert
Less than 1 second for the first disk activity to appear
