Module Remove and Replace 185
1 Examine the RAID controller or expansion IOM for damage, and closely inspect the interface
connector.
Do not install if the pins are bent.
2 Grasp the RAID controller or expansion IOM using both hands, and with the latch in the open
position, orient the module and align it for insertion into the target slot.
3 Ensuring that the RAID controller or expansion IOM is level, slide it into the chassis as far as it will
go.
A controller module that is only partially seated will prevent optimal performance of the RAID
chassis. Verify that the controller module is fully seated before continuing.
4 Set the module in position by manually closing the latch.
You should hear a click as the latch handle engages and secures the RAID controller or expansion
IOM to its connector on the back of the midplane.
5 Reconnect the cables.
NOTE: In a dual-controller system in which PFU is enabled, when you update the firmware on one
controller, the system automatically updates the partner controller.
Verifying Component Operation
RAID Controller
After replacing the controller module, verify that the CRU OK LED (rear panel) illuminates green,
indicating that the controller has completed initializing, and is online/operating normally.
• It may take two to five minutes for the replacement controller to become ready.
• If you are replacing either controller module, and PFU is enabled, you may need to wait 30
minutes to ensure that the two controllers—with their respective ownership of the disk
groups—have enough time to fully stabilize.
IMPORTANT: Use the disk management utility (GUI) or CLI to perform a restart
only
if necessary. See
the topic about restarting controllers in the
QXS G2 Disk Management Utility User Guide
for more
information.
Expansion IOM
If the storage system is configured with expansion chassis, the replacement expansion IOM may take
up to one minute to initialize after the cables are connected. Verify that firmware on both expansion
IOMs is compatible and current.
NOTE: See the topic about updating expansion chassis IOM firmware within the
QXS G2 Disk
Management Utility User Guide
