FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X5-2, X6-2 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

If Storcli package isn't installed on the server you can download a copy from the following Avago website: http://www.avagotech.com/support/oem/oracle/12gb/sas-12gbs-pcie-raid-hba-internal

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

2. Extend the server to the maintenance position

3. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis

4. Open the server fan door to gain access to the disk backplanes

5. Remove fan module FM0 (the left most fan viewing the server from the front)

6. Remove the PCIe riser from slots 3 and 4

7. Remove the internal host bus adapter card from the riser

Hold the riser in one hand and use your other hand to carefully remove the card from slot 4 of the riser
Disconnect the rear bracket attached to the PCIe card from the rear of the PCIe riser

9. Disconnect the SAS cables and the super capacitor cable from the internal HBA card and place the card on an antistatic mat

10. Use a No. 2 Philips screwdriver to remove the specially fitted bracket from the HBA card

NOTE: You will need to install the specially fitted bracket on the replacement HBA card. Set the bracket aside until you are ready to install the replacement HBA card

Install the Raid HBA

1. Unpack the replacement host bus adapter (HBA) card, the super capacitor, the SAS cables, and the super capacitor cable, and retrieve the PCIe riser for slot 3

2. Using a No. 2 Philips screwdriver, remove the standard HBA bracket that shipped with the replacement HBA card

3. Install the specially fitted bracket that was removed from the original raid HBA

4. Connect the SAS cables and the super capacitor cable to the internal HBA card

5. Insert the rear bracket on the internal HBA card into the rear connector on the PCIe riser

6. Insert the internal HBA card connector into the bottom connector on the riser for PCIe slot 3 and 4

7. Install the PCIe riser

8. Install fan module FM0

9. Close the server fan door

10. Return the server to the normal rack position

11. Reconnect the data cables to the server and reconnect the power cords to the server power supplies

12. Power on the server

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