Booting the Lattus Storage Node
1. Push the power button on the front of the Lattus Storage Node to boot it.
2. Check if the node has successfully booted and if the disks have been initialized by doing the following:
a. Look in the Events section of the
Dashboard
. When the machine has booted, you will see the two
events listed below:
l
Machine was rebooted
l
New empty disk(s) detected.
This event may take up to 15 minutes to appear in the Events
list. If you insert a disk that does have data on it, you will see the “New non-empty disk(s)
detected” event.
b. After the second event appears, go to
Dashboard > Administration > Lattus Management >
Logging > Jobs
.
