Goal

To replace a Brick RAID controller, perform the tasks that are outlined in the following table:

Step 1 Identify Identify the Target FRU.
Step 2 Prepare Prepare the System for FRU Replacement.
Step 3 Replace Replace the RAID or Expansion controller FRU:

• Remove a RAID or Expansion Controller to make room for the RAID or Expansion controller replacement.
• Insert a RAID Expansion Controller to insert the RAID or Expansion controller replacement.

Step 4 Verify Status Performed as final step in RAID or Expansion controller replacement.

DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: Understanding of Guided Maintenance in R4 and R5

TIME ESTIMATE: 30mins

TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS: Log onto the Axiom GUI / Client to access Guided Maintenance

PROBLEM OVERVIEW:

   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: FRU can be Normal/Failed/Warning

   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE: Read reference docs before proceding:

Pillar Axiom: How to use Guided Maintenance in R4 and How to identify a FRU

Pillar Axiom: How to use Guided Maintenance in R5 and How to identify a FRU

Remove a RAID or Expansion Controller
1 Within Guided Maintenance, follow the process onscreen to remove the controller.
2 If the Fibre Channel (FC) cables are not labeled to show where they connect on the controller, make a notation that shows which cable connects to which port.
3 When Guided Maintenance prompts you to remove the controller, disconnect all FC cables from the FC ports on the target controller.

To disconnect the cables, follow these instructions:

Important! Do not use force or rock the connector from side to side or up and down to remove it. Doing so will damage the socket. Also, for the FC cables:
● Do not pull on the FC cables.
● Do not apply sideways force on the FC cables.
● Do not pull the FC cables tight. Leave them slack at all times.

To disconnect the cables:
● For HSSDC2 connectors: Carefully grasp the cable connector and, while pushing the connector gently into the socket, press the latch on the top of the connector to unlatch it.
● For SFP connectors: Carefully grasp the cable connector and, while pushing the connector gently into the socket, press the latch on the bottom of the connector to unlatch it.

Then, gently pull the connector straight out to release the connector with the cable.

4 Unscrew the two screws that secure the locking tabs to the controller Casing. Springs retain the screws in the locking tabs.
5 Push the controller's two locking tabs down.

Result: The controller disengages from the Brick midplane.

6 Slide the controller out of the Brick chassis and set it aside.

Caution Immediately replace the component to maintain proper airflow and cooling. Over-temperature conditions will occur if the replacement FRU is not installed into the chassis. Over-temperature conditions can damage other components.

About Brick RAID or FC Expansion Controller Insertion
After you insert this FRU into a Brick control unit (CU), use Guided Maintenance to complete the replacement procedure.

When the FRU replacement process is complete, the Pillar Axiom system reports the status of the FRU.

Insert a RAID Expansion Controller
1 Slide the controller replacement into the Brick chassis until the controller stops.
2 Push up the two locking tabs on the controller to engage the controller with the Brick midplane.

Important! It is very important that the RAID controller locking tabs engage the midplane in a single motion. Partially closing the locking tabs on the RAID controller causes an incorrect data connection and the RAID controller is not allowed to power on. If the RAID controller does not immediately power on, remove it and wait 60 sec, then re-engage the
locking tabs with a single motion. If this does not resolve the problem, contact the Pillar World Wide Customer Support Center to continue Guided Maintenance for this FRU.

3 Screw the two Phillips screws into the controller casing to secure the locking tabs.
4 Reconnect all Fibre Channel (FC) cables into the FC ports on the replacement controller.

Important! Do not use force or rock the cable connector from side to side or up and down to insert it. Doing so will damage the socket. Also, for FC cables:
● Do not pull on them.
● Do not apply sideways force to them.
● Do not pull them tight; leave them slack at all times.
For complete information on how to cable a controller, refer to the Pillar Axiom 600 SSF Cabling Reference.

5 In the Guided Maintenance page, click Next.

Note: At this point, Guided Maintenance fails back the FC port group in the replacement controller so that these FC ports again support the data paths.

6 On the Verify page, click Verify Status.
If Guided Maintenance displays a verification failed message, click Try Again and re-seat the FRU. If the second attempt is not successful, contact the Pillar World Wide Customer Support Center to continue Guided Maintenance for the FRU.

Note: The length of time for the verification step to complete and the system to return a Normal status depends on the I/O load being carried by the system. For that reason, Pillar recommends that you lighten the I/O load as much as possible before replacing the FRU.

7 Review the status of the replacement FRU to confirm that it has a Normal status.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE: complete guided maintenance

PARTS NOTE:

Return parts if requested by Support/Engineering via the CPAS. Otherwise dispose of replaced parts as normal
