PROBLEM OVERVIEW: A Sun Fire X4800, Sun Server X2-8 (Sun Fire X4800 M2) Disk Backplane needs replacement

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

If the system is still up and functioning, customer should 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: If this server is part of an Exadata, please follow shutdown instructions in Section 1 of DOC ID: 1539451.1

How to shutdown the Exadata database nodes and storage cells in a rolling fashion so certain hardware tasks can be performed. (Doc ID 1539451.1)

How to Remove the Hard Drive Backplane

1.Shutdown OS and power off server.
2.Disconnect the AC power cables from the AC power block.
3.Label and remove the Disk Drives, CMODs and module fillers with their respective slot designation.
4.Label and remove the hard drives and any HD filler carriers.
5.To remove the three SAS connectors from the hard drive backplane, squeeze the connector lock clips and pull the connectors toward the back of the server .

Note:As you face the server, the lock clips are on the left side of the connector. From left to right, the cables are labeled SAS 1,SAS Power, and SAS 0. The right most cable, SAS 0, is color coded.

6.From the front of the machine, use a No. 1 Phillips screwdriver to loosen the three captive hard drive backplane retaining screws.
7.To remove the hard drive backplane and frame assembly from the server, slide it toward the back of the server, tilt the right side upward, and pull it out leading with the right edge.
8.Separate the HD backplane from the frame.

How to Install the Hard Drive Backplane

9.Join together the backplane and the frame.
10.Orient the hard drive backplane assembly with the connectors on the backplane facing toward the back of the server.
11.Insert the hard drive backplane into the server and position it against the back wall of the drive bay.
12.Hold the hard drive backplane assembly flat against the back wall of the drive bay and align the screw holes in the assembly with the captive screws.

Note: For ease of installation, align the center screw first.

13.From the front of the server, use a No. 1 Phillips screwdriver to tighten the three captive screws and secure the hard drive backplane assembly.
14.Connect the SAS cables and the one SAS power cable to the hard drive backplane.
15.Install the hard drives into their original slots.
16.Install the CMODs and filler modules into their original slots.
17.Install the AC power cables.
18.Prepare the server for operation.

How to verify the DBP working properly.

Note: If this server is part of an Exadata, please follow restart instructions in Section 1, step 10 of DOC ID: 1539451.1

Power on server and log in ILOM to confirm if DBP working and all HDD status working properly.

Sample

-> show /SYS/DBP -l all

/SYS/DBP
Properties:
type = Disk Backplane
ipmi_name = DBP
fru_name = ASSY,BACKPLANE HDD,C4
fru_manufacturer = 9615 HON HAI PRECISION CO. LTD SHENZHEN GUANGDONG CN
fru_part_number = 511-1062-06
fru_serial_number = 0226LHF-1039AB00VF

/SYS/DBP/HDD0
Properties:
type = Hard Disk
ipmi_name = DBP/HDD0

/SYS/DBP/HDD0/PRSNT
Properties:

value = Off

/SYS/DBP/HDD0/OK2RM
Properties:

Check ILOM event log to see if any error related HDDs.

-> show /SP/faultmgmt
-> show /SP/logs/event/list

Check if the HDD working normal from LSI Niwot REM/Erie RAID controller.

For LSI Niwot REM controller.

Check if all HDDs working normal on Solaris environment.

1.Use format command to check HDD status

# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
0. c0t0d0 <DEFAULT cyl 36348 alt 2 hd 255 sec 63>
/pci@0,0/pci8086,3408@1/pci1000,9262@0/sd@0,0

2.Use iostat command to check HDD status

# iostat -E
sd1 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: LSI Product: MR9262-8i Revision: 2.90 Serial No: Size: 299.00GB <298999348736 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 2 Predictive Failure Analysis: 0

3.Use cfgadm command to check HDD connection

# cfgadm -alv
Ap_Id Receptacle Occupant Condition Information
When Type Busy Phys_Id
Slot3 empty unconfigured unknown Location: Slot3
Jan 1 1970 unknown n /devices/pci@79,0/pci8086,340a@3:Slot3

c0::dsk/c0t0d0 connected configured unknown LSI MR9262-8i

4.Use raidctl -l command to see if HardRAID working normal.

Platforms using Solaris 10 Update 3 or lower will produce similar to the following output when configured under LSI hardware RAID management:

Good Volume:

# /usr/sbin/raidctl -l

RAID Volume RAID RAID Disk
Volume Type Status Disk Status
------------------------------------------------------
c1t0d0 IM OK c1t0d0 OK
c1t1d0 OK

Platforms using Solaris 10 Update 4 or higher will produce similar to the following output when configured under LSI hardware RAID management:

Good Volume:

# /usr/sbin/raidctl -l

Controller: 0
Volume:c1t0d0
Disk: 0.0.0
Disk: 0.1.0

5.check /var/adm/message file if any warning/error related HDDs
