FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:


PROBLEM OVERVIEW: An Oracle Server X7-2L Internal RAID HBA Card needs replacement


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


If the system is up and functioning, customer should revert all the RAID disk volumes to WriteThrough mode to ensure all data in the RAID cache memory is flushed to disk and not lost when replacement of the HBA occurs. As 'root' user, set all logical volumes cache policy to WriteThrough cache mode:


# StorCli64 -ldsetprop wt -lall -a0


Verify the current cache policy for all logical volumes is now WriteThrough :




# StorCli64 -ldpdinfo -a0 | grep BBU


Default Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Default Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU




Once the RAID cache is in WriteThrough mode, perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system.


A data backup is not a prerequisite but is a wise precaution.


 


Note: MegaCli commands can be run on StorCli utility as well


 


 


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:


Removing the RAID HBA:


1. Prepare the server for service


    

  1. Power off the server and disconnect the power cords from the power supplies.
    2. 

  2. Extend the server to the maintenance position.
    3. 

  3. Attach an antistatic wrist strap.
    4. 

  4. Remove the server top cover.
    5. 



2. Rotate the PCIe card locking mechanism, and then lift up on the RAID HBA card to disengage it from the motherboard connector.


3. Disconnect the super capacitor cable and the SAS cables from the Oracle Storage 12 Gb/s SAS PCIe RAID HBA card.


    

  1. Grasp the RAID HBA, press in on the release latch for the super capacitor cable, and then unplug the cable from the connector.
    2. 

  2. To disconnect the SAS cables between the Oracle Storage 12 Gb/s SAS PCIe RAID HBA card in PCIe slot 6 and the front storage drive backplane, press each latch, and then pull out to disengage the cable from each SAS connector.
    3. 



4. Lift and remove the Oracle Storage 12 Gb/s SAS PCIe RAID HBA card.


5. Place the Oracle Storage 12 Gb/s SAS PCIe RAID HBA card.


 


Install the RAID HBA:


1. Unpack the replacement Oracle Storage 12 Gb/s SAS PCIe RAID HBA card and place it on an antistatic mat.


2. Connect the super capacitor cable to the Oracle Storage 12 Gb/s SAS PCIe RAID HBA, and then reconnect the SAS cables that you unplugged during the removal procedure.


3. Insert the Oracle Storage 12 Gb/s SAS PCIe RAID HBA card into PCIe slot 11, and rotate the PCIe locking mechanism to secure the PCIe HBA card in place.


4. Return the server to operation.


    

  1. Install the top cover.
    2. 

  2. Return the server to the normal rack position.
    3. 

  3. Reconnect the power cords to the power supplies and power on the server.
    4. 



5. Use Oracle ILOM to clear any server PCIe card faults, if any.


 


OBTAIN CUSTOMER ACCEPTANCE


 


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


Boot up system and if necessary you may need to import the foreign configuration detected on the hard disks after the HBA replacement, when prompted during the boot process press Ctrl+R to Run LSI Configuration Utility.
Use CTRL+N to navigate to the VD MGMT screen, highlight the controller, press F2, Foreign config, Import/Clear.


Once the OS is booted, login as root and set all logical drives cache policy back to WriteBack cache mode:


# StorCli64 -ldsetprop wb -lall -a0


 Verify the current cache policy for all logical drives is using WriteBack cache mode:


# StorCli64 -ldpdinfo -a0 | grep BBU

Default Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
Default Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
