Always use the storage-management software to identify the failure.
Use the following steps to verify the RAID storage controller, storage unit, drives, all
components of the boxes and all interconnections between the boxes:
v
Start SM7 via Terminal Services
v
After it starts, click on the flashlight button so it will find the subsystems. It should
display the subsystem trees.
v
Double click a subsystem to bring up the management window which will show
the subsystem tree with an unconfigured capacity branch.
v
Verify that the unconfigured capacity matches the total that is supposed to be
attached to that RAID controller.
v
Verify that the
″
thermometer/fan/battery
″
button on the right side of each
enclosure picture is GREEN
v
Right click the subsystem listed at the top of the tree and select
locate
v
Verify that the amber light on all drives attached to that RAID controller are
blinking. The drives
do not
have to be initialized to blink the drive lights.
Table 12 on page 40 lists the external indicators on the storage unit and
explanations for the different states of the indicators.
