Symptoms

Unrecoverable read errors may occur on certain disk drive models. Affected drive models and the products which may contain them are listed below.

Cause

The vendor has determined that unrecoverable read errors may occur on certain disk drive models when a burst of I/O activity follows an extended idle period.

Solution

A firmware update is available to address the condition described above. There are two methods based on the OS platform used for your server running Sun Storage Common Array Manager (CAM):

• For Solaris SPARC and x86
• For Windows and Linux

For Solaris SPARC and x86

The firmware update is included in CAM 6.10.2 for Solaris users. Please refer to the following documents:

• <Document 1011180.1> How to Determine the Version of Sun Storage Common Array Manager (CAM).
• <Document 1296274.1> How to Download Common Array Manager (CAM) Software and Patches to download CAM 6.10.2.
• <Document 1926022.1> Sun Storage Common Array Manager (CAM): How to Upgrade Firmware for Sun Storage 2500, 2500-M2, 6000 Arrays, J4000 JBODs, and F5100 Flash Arrays.

For Windows and Linux

1. You will need to have CAM 6.9 installed. Please refer to the <Document 1011180.1> How to Determine the Version of Sun Storage Common Array Manager (CAM).
   
   
   • If you need to upgrade to CAM 6.9, please refer to the <Document 1296274.1> How to Download Common Array Manager (CAM) Software and Patches and the instructions "Installing the Management Host and Optional GUI" to upgrade CAM.
   • If you already have CAM 6.9, please proceed to next step.
     
     
2. List the drive models installed in your array and their firmware levels:
   
   
   • Using the GUI:
     
     
     1. Log into the CAM GUI.
     2. Expand the tree for the array on the left hand side.
     3. Expand "Troubleshooting".
     4. Click on "FRUs".
     5. Click on "Disk" in the table which is listed.
     6. Click on the disk you want.
     7. Look at the "Firmware Package Version" and "Physical ID".
        
        Example:
        
        
        
        
        
   • Using the CLI:
     
     
     1. Execute the following command to list the drives in your array:
        
        
        sscs list -d <arrayname> -t disk fru
          
        
        
        /* `sscs` is under:
        /* Solaris: /opt/SUNWstkcam/bin/
        /* Linux: /opt/sun/cam/bin/
        /* Windows: C:\Program Files\Sun\Common Array Manager\bin
          
        
        
     2. Execute the following command to list details for a specific drive and look at the output for "Firmware Package Version" and "Model":
        
        
        sscs list -d <arrayname> -t disk fru <drive>
          
        
        Example:
        
        # sscs list -d myarray -t disk fru Tray.01.Drive.01
        
        Assignable                        : False
        Availability                      : Running Full Power
        ...
        ...
        FRU Number                        : 5QG1M9WW
        FRU Type                          : HDD
        Firmware                          : 0706
        Firmware Package Version          : 0706                <--- Firmware Package Version
        Hot Spare                         : False
        ...
        ...
        Media                             : HDD
        Model                             : ST35000NSSUN500G    <--- Drive model
        Name                              : Tray.01.Drive.01
        Non Redundant Access              : False
        Offline                           : False
        ...
        ...
        #
          
        
        
3. If you do not have drive models equivalent to the one listed in the table of this document, your array is not affected by the issue in scope of this document and you can stop here. Otherwise, please proceed to next step.
   
   
4. Download from the list below, the firmware file needed for your array and drive model:
   
   
   
   • 2510, 2530 and 2540:
     
     Drive model: HUS1530SCSUN300G    Firmware file: D_HUS1530SCSUN300G_A820_LCA.dlp
     Drive model: HUS1560SCSUN600G    Firmware file: D_HUS1560SCSUN600G_A820_LCA.dlp
     
     
   • 2530-M2 and 2540-M2:
     
     Drive model: H109060SESUN600G    Firmware file: D_H109060SESUN600G_A720_SNM.dlp
     Drive model: HUS1530SCSUN300G    Firmware file: D_HUS1530SCSUN300G_A820_SNM.dlp
     Drive model: HUS1560SCSUN600G    Firmware file: D_HUS1560SCSUN600G_A820_SNM.dlp
     
     
   • 6140, 6540, 6180, 6580, 6780 and CSM200:
     
     Drive model: HUS1530FCSUN300G    Firmware file: D_HUS1530FCSUN300G_E820.dlp
     Drive model: HUS1561FCSUN600G    Firmware file: D_HUS1561FCSUN600G_E820.dlp
     
     
5. Save this firmware file into a directory of your CAM server. The default directory where the CAM firmware images stored are mentioned below:
   
   
   Solaris: /opt/SUNWstkcam/share/fw/images
   Linux: /opt/sun/cam/share/fw/images/disk/
   Windows: C:\Program Files\Sun\Common Array Manager\Component\SunStorageTekArrayFirmware\images
     
   
   
6. Ensure that all the I/O in your array is stopped before proceeding to the next step.
   
   
   Important: Drive firmware cannot be upgraded with I/O running in the array.
     
7. Because we use drive firmware files which are not bundled with CAM, we can only use the command line (CLI) to upgrade the firmware. Execute the following command in order to upgrade the firmware:
   
   
   # sscs modify -a <arrayname> -o -t disk -p <path to your drive firmware file> -c <drive> firmware
     
   
   Example:
   
   
   Note: This example uses a firmware file which is unrelated to the issue in scope of this document.
     
   
   
   # sscs modify -a <myarray> -o -t disk -p ./D_ST314655SSUN146G_0D92.dlp -c Tray.00.Drive.02 firmware
   
   WARNING: You selected a manual firmware install file. You must use only valid
   firmware from Sun. Unsupported firmware can DAMAGE your array severely.
   Check the status of all components before downloading firmware.
   WARNING:  This command will load new firmware if needed and may impact
   array management and data availability.

8. Repeat the above step 2 to confirm that the drive firmware has been upgraded.
   
   
9. Once you have completed the drive firmware upgrade, you can resume the I/O in your array.
