PROBLEM OVERVIEW: A Sun Fire X4170 M2, Sun Server X3-2, Exalogic X2-2, X3-2, X4-2 SSD needs replacement

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

Note: This process is NOT intended to be used for proactive disk drive replacements where the drive has NOT been failed by the RAID Controller. If you are performing a proactive disk replacement, you should seek additional help from Oracle Support.

The SSD drive is part of a mirrored RAID volume and is hot swappable. Therefore it can be replaced at any time, however care should be exercised to ensure the volume is in an appropriate state (Degraded) and that you are removing the proper device.

The volume State should be listed as 'Degraded' when running the following command:

# /opt/MegaRAID/MegaCli/MegaCli64 -Ldinfo -lAll -aAll

Adapter 0 -- Virtual Drive Information:
Virtual Drive: 0 (Target Id: 0)
Name :
RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0
Size : 28.870 GB
State : Degraded
Stripe Size : 64 KB
Number Of Drives : 2

Default Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Access Policy : Read/Write
Disk Cache Policy : Disk's Default
Encryption Type : None

The physical disk may have the amber LED illuminated, though this is not a requirement. The drive 'Firmware State' should be something other than 'Optimal, Spun Up', though it is also possible that the drive will be missing from the drive list completely. The drive state can be seen using the following command:

# /opt/MegaRAID/MegaCli/MegaCli64 -PdList -aAll

Note: The above 'Firmware State: Unconfigured(bad)' was from a injected fault which was caused by a mock drive replacement (drive replaced with itself). Though this is a valid fault, it is important to note that this type of fault requires additional manual steps to completely recover the volume that are not discussed within this document.

- WHAT ACTION DOES THE ADMINISTRATOR NEED TO TAKE:

1. Identify the system with the failed SSD drive. Be sure to note he drive number  (slot) that has failed, the drive may also have the amber light illuminated. The following commands will also give you status information for the RAID volume and physical drives.

RAID Volume:
# /opt/MegaRAID/MegaCli/MegaCli64 -LdInfo -lAll -aAll

Physical Drives:
# /opt/MegaRAID/MegaCli/MegaCli64 -Pdlist -aAll

2. Once you have verified that the drive is in the correct state and the amber light is illuminated. Press the release button on the failed drive.
3. When the drive tray opens, remove the drive from the compute node by pulling gently on the drive handle.
4. Insert the new drive tray in the empty drive slot in the compute node by sliding the drive tray into the slot and pushing until the handle clicks.

Note: It is generally a good practice to wait at least 1 minute between part removal and insertion.

5. Verify that the new drive is detected. The firmware state

6. You may also want to verify that the drive's reconstruction is in progress.

# /opt/MegaRAID/MegaCli/MegaCli64 PDRbld ShowProg PhysDrv [252:0] -aAll

Rebuild Progress on Device at Enclosure 252, Slot 0 Completed 60% in 1 Minutes.

Note: The [252:0] is the 'Enclosure Device ID' and the 'Slot Number', which can be obtained from 'MegaCli64 -PdList -aAll', see output from step 5 above.


Verify status of RAID Volume and ensure appropriate status, the volume rebuild process will normally complete in 5-20 minutes.

example: This is the final expected volume and disk drive states.
