 How to replace a Disk drive in an PCA upgrade compute node server (X7-2)

Solution

CAP PROBLEM OVERVIEW: Disk Drive Replacement
DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Sun Server X5-7 Server Training.
PCA X5-2 Training

TIME ESTIMATE: 10 minutes

TASK COMPLEXITY: 0-CRU

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The server supports hot-plugging of the storage drives so a complete power down of the server is not required if your storage/OS configuration allows for a hot-plug operation.

The two HDD’s in each server are setup as a single  RAID 1 mirror

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.
 1.1   Replacing a drive does not require removing the server from a rack
 1.2   The hard-disk drives (HHDs) in the server are hot-pluggable,

2. Confirm the  Storage Drive failure and it's location.
 2.1    Confirm which Storage Drive is to be replaced.
 2.2    The drive location.  The bottom row contains disks 0,2,4,8  from left to right.   The top row contains 1, 3, 5 and 7  left to right.

3. Remove the Storage Drive
 3.1   On the drive you plan to remove, push the latch release button to open the latch. (Caution - The latch is not an ejector. Do not bend the latch too far to the right. Doing so can damage the latch.)
 3.2   Grasp the latch and pull the drive out of the drive slot.
 3.3   Place the drive on an antistatic mat.

4. Install the replacement Storage Drive
 4.1   Remove the replacement drive from its packaging and place the drive on an antistatic mat.
 4.2   Align the replacement drive to the drive slot. The drive is physically addressed according to the slot in which it is installed. It is important to install a replacement drive in the same slot as the drive that was removed.
 4.3   Slide the drive into the bay until the drive is fully seated.
 4.4   Close the drive latch to lock the drive in place.

To check the status of the drives from the OS of the compute node you can run:

(This is the output from a healthy compute node.) 
There are two logical volumes across two drives in slots 0 and 1 in a raid 1 mirror.   A management node only has one logical volume configured in a raid 1.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

No action should need to be taken for a hot swap replacement of the a disk drive.
