6.0 Microcode Readme Change History

=====================================================================================

1.0 Microcode Change History:
NOTE:  There were major changes between the "04xxxxxx", "03xxxxxx" and "02xxxxxx" microcode levels. 

For updating between those levels (and in general), if you have are using CCIN 57CF PCI-E SAS Planar RAID Controllers, CCIN 57B8/57B7 SAS RAID Enablement Features or CCIN 572F/575C DoubleWide SAS Adapter, please update both adapters.

Also, in a Dual Controller environment, it is advisable to update to the same microcode level on both adapters.

 

0422003f -New Fcode 290 resolving very intermittent boot issue where the disk drive (SAS boot source) may not be found. This issue has been experienced only in model "D" systems.
-During IPL, 066B9100 may be logged due to a SAS path may become active after the initial verification has been performed (CCIN 57CB & 2B4C)
-FC5904, FC5906, FC5908 (CCIN: 572F) adapter may become unresponsive during extended periods of inactivity (i.e. applying group PTFs or other PTF packages) possibly resulting in SRC A6000255
-A replacement of a failed mirrored device in a dual storage adapter configuration may result in a false Reclaim Cache being required.
0422003a -Blades only change to address booting issue. This does not affect any other environment.
The intended environment for the result of the change is a very specific configuration: Power 7 Blade in BCS with SAS Switch Module routing to Disk Storage Module with a specific User Configured SAS Zoning setup.
04220037 -Removed SAS Adapter's initiation of the SES LED lamp check function.
This change resolves some recent field issues (circa 2012) where DASD backplane LEDs stayed on due to bus contention on the I2C bus. This was mainly seen in 8205-E6B/E6C split backplane configuration. Without this microcode, the likelihood of encountering the issue varied based on the installed System FW level.
-Possible system hang during replacement of a mirrored disk drive in a Dual Storage IOA configuration
-04448400 Adapter Unit Check following hot spare rebuild on array optimized to secondary adapter.
*** Only occurs if drive is replaced during the hot spare rebuild. Dual Controller Only
-Fix for SISSAS_FABRIC_ERRs (during SAS Speed Negotiation) w/ HHLT05 tape attached to CCIN 57B8
-IBM i ONLY: SAS I/O adapter enhancements during error recovery to prevent a very slight chance of undetected data corruption.
Feature codes affected are FC5904, FC5906, FC5908, FC5903, FC5805, FC5662, FC5630, FC5268, FCEJ0F, FCEJ01
-Possible system hang caused by incorrect error recovery due to a SAS Port failure
DH_PRC_JADE_HDWMGR_KAM_TABLE_PTY_ERR
04220033 -Minor fixes for the following error codes IOASC/PRC
06690200/14021403, 07278C00/17034918, 04448200/11050E51, 02048000/17101c15, 04448400/17034a25
-New DDR2 register settings for 572C in 9117-MMB, 9179-MHB
0422002b -GA level for CCIN 57CC in 9117-MMC, 9179-MHC.  Specific phy mapping changes to enable attached DVD correctly.
NOTE:  This code was burned on to the IO planars containing CCIN 57CC and was never released as an updatable microcode image.
04220029 -Specific to MTM 8202 & 8205: Reduction in I2C bus traffic, eliminating unnecessary communication to PSOC.
This change has shown to resolve situations where one Virtual "ses" device would configure as defined in DASD split backplane configurations.
Note: This microcode change does not resolve other I2C bus contention issues outside of the SAS architecture.
-Contains fixes, previously included in 042x001b levels for Power Blade architecture (1 SAS Address per phy)
-Added Error Code combo 04678000/10440039 to report invalid Dual Controller configurations. Previous undetected invalid configurations included: MTM 8202/8205, High End DASD backplane without CCIN 2BD9 & 2BE1)
-Fix for SSD drive errors, 0B/4400 in CCIN 57CD configuration. Reduced Overall Command Timeout Value from 16 to 2.
-Various other fixes/enhancements
04220025

Level 04220020 + 1 additional fix
SAS I/O adapter error recovery enhancements to prevent a very slight chance of undetected data corruption
All of the following must be true for their to be even a slight chance of undetected data corruption
1) Large Sequential Writes
2) JBOD (non-RAID) configuration (this will not occur with RAID configurations)
3) Both SAS ports of the SAS Adapter must be used
4) Performance degradation due to incorrect PCI-E bus training

Adapter microcode update prevents the problem from occurring.  Affected feature codes include: FC5278, FC5901, FC5911.
If the first 3-of-4 cases, above, remain true then applying the adapter microcode fix may cause performance degradation, for the above feature codes.
That being said, the microcode fix also enhances the PCI-E bus training to further eliminate possible conditions where the PCI-E bus will train incorrectly thereby correcting performance issues caused by an incorrectly trained PCI-E bus.
This microcode fix will not cause performance degradation for RAID configurations nor JBOD configurations with read workloads.
For concerns, call IBM Service.
04220020 Level 04220019 + 1 additional fix
SAS I/O adapter error recovery enhancements for device hard media errors to prevent a very slight chance of undetected data corruption. This can only occur when a RAID-5 configuration is being used. The adapter microcode is
updated to prevent the problem from occurring.
Affected CCINs:  All that are RAID 5 capable
Affected feature codes include: FC5912, FC5679, FC5904, FC5906, FC5908, FC5901, FC5278, FC5903, FC5805, FC2053, FC2054, FC2055, FC5662, FC5630, FC5267, FC5263, FC5268, FC5900, FC5902, FC5909, FC5911, FC5652, FC5631, FC5618
04220019 GA level of CCINs 2BD9, 2BE0, 2BE1, 572C features specific to 8202-E4B, 8205-E6B, 8231-E2B
GA level of CCIN 57CD
-Minor enhancements for error conditions
-Enhancement to SAS Controller Inquiry Page D0 response to encode the resource address differently.  This code level, or above, may be necessary for Blade configurations with AIX levels released in the 2011 and beyond timeframe.
04220010 First customer release in the "04xxxxxx" level.
0422000e GA level for CCIN 57C7 & 57CF.  This code level was never release to the customer website.
HIPER:  Early Ship customers (ESP) may have 04220009.  If this is the case please update your code immediately.
03220066

Fixes for

·        All Adapters: IOASC/PRC 04448400/80FF0200, 04448400/80FF0300, 06678400/104212C2

·        non-RAID (JBOD) only:  04448400/10802033

·        Dual Controller only:  IOASC/PRC 06678400/10440C10

·        Dual Controller w/ Active/Active only:  Changes to quiesce drive ops on drives that are not performing write same commands upon insertion of DASD (RAID and non-RAID)

·        CCIN 57B8, 572F (on Link to Aux Cache):  IOASC/PRC 01080000/10272385
03220063

-Coincides with announcement of Dual Controller 572F/575C support (10/30/2009 GA)

-There was a small possibility that the SAS Controller’s VPD update process could be interrupted on the first pairing of a 8204/8203 System Planar & 57B8 SAS RAID Enablement Card.  This could leave the 57B8 in an unusable state.  See Retain Tip H195958.  This microcode moves the VPD update to a place in time to avoid the interruption.

-Skip Operation improvements for SSD devices

-572F/575C.  Fix for 9071 & 9072 errors on boot

-Close loophole on microcode update to a SES (split-backplane) which could potentially allow for microcode update both SAS paths to a particular device.  If both paths are being updated then no paths would be active to the end device.

-Fixes for various Adapter Unit Check conditions.

-Fix for JS23 Blade (57D0) w/ NSSM.  Tape connected to Port 4 would not configure
03220060 -Convergence of microcode paths.  The fixes in 03220059 and 03220056 are contained in this code along with others.
03220059

HIPER:  It is of utmost importance to install this fix if Active/Active is enabled in a Dual Controller environment.  Prior to updating, it is required to update any attached "STxx" model SAS DASD.  See the respective "STxx" microcode readmes for the minimum required microcode levels.

 

This code level is based off 03220051.  It does not contain the fixes in 03220056.

  • Active/Active fix:  One or more disks could get lost from an array when a Link error occurs.  This posed a Data Loss possibility.  It is strongly recommended that Active/Active be disabled when installing this microcode!  Active/Active can be re-enabled, concurrently, after microcode installation on both adapters.

  • Microcode Download update incomplete fix:  The possibility existed where future microcode download attempts will not complete successfully and thus need to be retried.  Once this code is successfully flashed that possibility is removed.
03220051

-NOTE:  This code is only useful for CCIN 57BA, FC 5911.  There is no need to install this level on other features.

03220048 + 1 additional fix to address errors in CCIN 57BA, FC 5911 environment.

Errors:

SISSAS_ERR11T w/ error code FFFE
SISSAS_FABRIC_ERROR w/ error code 4100 or 4101
03220048

-Add support (GA Level) for

  • CCIN 572F, 574E, 575C, 57B3, 57B7 (revision), 57BA, 57D0

  • SSD DASD

  • Blade environment options coinciding with May 2009 release: 

    • 7778-23X

    • BCS DASD control

    • NSSM

    • RSSM

    • DS3200

-Allow for 6G devices under an expander.  Devices will run at 3G

-Various Unit Check fixes

-Dual Controller mode:  Enabled Active/Active mode

NOTE:  There were major changes between the "03xxxxxx" and "02xxxxxx" microcode level.  If you have are using 57B8/57B7 SCSI RAID Enablement Features please update both adapters.
02220070

-Fix for 04448400 with 10272212 and other Unit Checks conditions.

-Corrects a situation where adapter did not enable caching in a specific dual controller scenario.
0222006b -Code level 02220065 + 1 additional fix addressing PCI-E training issue affecting 57B7 and 57B9 SAS adapters.
02220065 -Fix for out of resources error.  The SAS/SCSI controller would previously allow for up to 16 resources per drive.  This has been increased to 20 to coincide with the theoretical maximum.
02220060 -Fix for 57B7 no show on boot.  New PCIe driver strength settings and change to the PCIe CORE reset pulse.
02220059 -Fix for 572B in Dual Controller mode.  The adapter will no longer log a 9076 error on a boot, if the system contains 572B's that have no FC 5886 SAS drawers attached.
02220056

-CCIN 572A & 57B9 enhancement to add 2 extra retries upon configuration.  This modification was made to more reliably configure split backplane configurations without AIX reporting errors.  For these split backplane configurations, please install this code along w/ 9117-MMA SES microcode level 0021 or 8204-E8A/8203-E4A SES microcode level 0008

-Various Target Mode/Dual Controller enhancements.
02220050 GA Level for CCIN 57B9
0222004a Fix for TEMP SISSAS_ERR11T logged against CCIN 57B7 during boot or other configuration time. That error decoded further as a REASON FOR FAILURE Timeout - op started. A microcode update to 57B8 addresses the issue.  It is best practice to apply the update to 57B7 when updating 57B8.
0222003c Various Unit Check condition fixes (04448400 and 04448200 errors)
02220039 GA Level for CCIN 57B7

3.0 Determine the Current Microcode Level for AIX:

Before you install the microcode, it is important to determine the microcode level of the Adapter installed in the target system. Use

the following instructions to read the ROM level stored in the Adapter's VPD.

1)  List the SAS RAID Adapters installed in the system by typing:

    lsdev -C | grep sissas

Note: All of the SAS RAID initiators addresses that are installed will be displayed. The names will be sissasX, where X is 0, 1, etc.

2) To check the current microcode level for the adapter or controller enter the following command

   lscfg -vl sissasX

Where X is the number/s of the previous command. The Command will produce output similar to

 

For example, (574E)

DEVICE   LOCATION                                     DESCRIPTION

sissas1      U5802.001.B93SX3Y-P1-C6-T1      PCI Express x8 Ext Dual-x4 3Gb SAS RAID Adapter

PCI Express x8 Ext Dual-x4 3Gb SAS RAID Adapter :
Part Number.................44V7436
FRU Number..................44V7436
Serial Number...............YL10D8355051
Manufacture ID..............000D
EC Level....................0
ROM Level.(alterable).......03220047
Customer Card ID Number.....574E
Product Specific.(Z1).......1
Hardware Location Code......U5802.001.B93SX3Y-P1-C6-T1

 

If the ROM Level is less than 0422003f then you should update the microcode.

 

3.1 Determine the Current Microcode Level for Linux:
1) Type "iprconfig"
2) Select "Display hardware status"
3) Select SAS adapter by typing a "1" in front of it and pressing Enter.
4) The Command will produce output similar to
"Firmware Version . . . . . . . . . . . . : 02220070"

If the Firmware Version is less than 0422003f then you should update the microcode.

4.0 Downloading and Unpacking the Firmware Update Package from CORE

NOTE:  The CORE image will now be the RPM Format File.

1) After downloading the files from CORE on to your personal system find the following files in the CORE destination directory (c:\ibmdocs\DISKIMG):
    A) "pci.10140339.22.0422003f-1.aix5.1.noarch.rpm"
    B) "pci.10140339.22.0422003f-1.Linux.noarch.rpm"
2) Log in to the Target Server
3) Create a directory, if not already existent (mkdir /tmp/microcode; mkdir /tmp/microcode/RPM)
4) Transfer the file to the Target Server "/tmp/microcode/RPM directory" using ftp or another method.  Change to that directory, "cd /tmp/microcode/RPM".
5a) For AIX:  Unpack the RPM file by using the following command:  "rpm -ihv --ignoreos --force pci.10140339.22.0422003f-1.aix5.1.noarch.rpm"
5b) For Linux:  Unpack the RPM file by using the following command:  "rpm -ihv --ignoreos --force pci.10140339.22.0422003f-1.Linux.noarch.rpm"
6a) For AIX:  The microcode files will be added to /usr/lib/microcode/.
6b) For Linux:  The microcode files will be added to /lib/firmware/.

4.1 Downloading the RPM Format File to the Target Server
Use this method to download to an AIX or Linux system:

Note: The instructions that follow are specific AIX/Linux commands. AIX/Linux commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.

1) Make a directory on an AIX/Linux system to receive the RPM format file.

    Enter: "mkdir /tmp/microcode"
    Enter: "mkdir /tmp/microcode/RPM"
2) Transfer the RPM format file to the /tmp/microcode/RPM directory (using "Save as ...").  Change to that directory, "cd /tmp/microcode/RPM".

You'll see the filenames for the RPM files.
    A) For AIX:  The filename is pci.10140339.22.0422003f-1.aix5.1.noarch.rpm
    B) For Linux:  The filename is pci.10140339.22.0422003f-1.Linux.noarch.rpm
3) Unpack the file by executing the instructions below:
    A) For AIX:  Type "rpm -ihv --ignoreos --force pci.10140339.22.0422003f-1.aix5.1.noarch.rpm"
    B) For Linux:  Type "rpm -ihv --ignoreos --force pci.10140339.22.0422003f-1.Linux.noarch.rpm"
4a) For AIX:  The microcode files will be added to /usr/lib/microcode/.
4b) For Linux:  The microcode files will be added to /lib/firmware/.
 

4.2 Microcode Update via CD

Below are references and the general flow on how to update microcode update via CD
1) Boot the system via a Standalone Diagnostic's CD
b) To create a bootable Diagnostic's CD go to the following URL.
Burn cdlatest.iso on to a CD-R (or CD-RW). Currently, DVD media cannot be utilized.
http://www14.software.ibm.com/webapp/set2/sas/f/diags/home.html
c) After booting to Standalone Diagnostics, the Diagnostic's CD can be removed.

2) The Diagnostic's CD should be replaced by a CD containing the unpacked microcode image(s).
The CD containing the microcode images should be prepared prior. This can be done by taking the rpm file(s) from the microcode download site and unpacking them on a usable server. The unpacked files can then be burned on to the CD media.
b) Another method is to use a Microcode Update CD
See the below website for more details

5.0 Verifying microcode before download and notes

NOTE: Microcode download must be performed separately for each Adapter bus under distinct Logical Partitions (LPAR's).
              Please save current and older versions of the microcode update files in case you need to restore your system.

NOTE: Microcode Download CAN be performed concurrently.

Installation Time:  Approximately 30 min System Time.

Please verify the file size and checksum of the raw microcode files matches the below.
Filesize:  1364124
Checksum:  38532
For AIX:  "ls -l /usr/lib/microcode/53495322.0422003f" to verify Filesize. 
                "sum /usr/lib/microcode/53495322.0422003f" to verify Checksum.
For Linux:  "ls -l /lib/firmware/pci.10140339.22.0422003f" to verify Filesize.
                 "sum /lib/firmware/pci.10140339.22.0422003f" to verify Checksum.

For systems that have LPAR installed, the microcode file must be placed on all partitions that have a SAS device in order to update the code.  Follow this procedure for each partition:

For AIX:
    A)  Log into the target partition.
    B)  Type: "cd /usr/lib/microcode"
    C)  FTP (for AIX) or SFTP (for Linux) to the partition that has the media bay assigned. (ie.  ftp/sftp partition1.ibm.com)
    D)  Type: "cd /usr/lib/microcode"
    E)  If using FTP then Type: "bin"
    F)  Type: "get 53495322.0422003f"
    G)  Type: "quit"

For Linux:
    A)  Log into the target partition.
    B)  Type: "cd /lib/firmware"
    C)  SFTP to the partition that has the media bay assigned. (ie.  "sftp partition1.ibm.com")
    D)  Type: "cd /lib/firmware"
    E)  Type: "get pci.10140339.22.0422003f"
    F)  Type: "quit"

5.1 Microcode Download Procedure-SAS Adapters for AIX

Procedure:
1) It is advised, but not necessary to stop all applications.
2) Enter diag
3) Select the "Task Selection" from diagnostics menu.
4) Select "Download Microcode" or "Microcode Tasks -> Download Microcode" from "Task Selection" menu.
5) Select all of the SAS Adapters/Controllers that need to be updated from the list of devices by pressing "Enter".  The devices will be displayed as sissas#, where # is the number of the device.  Press "F7".
6) A dialogue box will be displayed on screen.  Press "Enter" to continue.
7) Select "/usr/lib/microcode".
8) A dialogue box will may be displayed on screen.  It will state that the current microcode level on the adapter is not in the /usr/lib/microcode directory.  This is acceptable as you will be flashing new microcode onto the adapter.  Also, incorrect code will automatically be rejected.  Press "Enter" to continue.
9) An "M" will be displayed next to the latest level of microcode in the /usr/lib/microcode directory.  Select that level and press "Enter".
10) The following message will appear on the screen when download is completed: "Microcode download complete successfully.  The current microcode level for the device sissas# is .....  Please run diagnostics on the adapter to ensure that it is functioning properly."  DO NOT run diagnostics on the device at this time.
11) Exit diagnostics.
12) Verify the code level is 0422003f by typing "lscfg -vl sissas#" for each SAS device updated. <Where # is the number sissas device>

5.2 Microcode Download Procedure-SAS Adapters for Linux

Procedure:
1) Stop all applications.
2) Type "iprconfig" and press "Enter".
3) Select "Download Microcode" and press "Enter".
4) Select all of the SAS Adapters/Controllers  that need to be updated from the list of devices by pressing "1". Then press "Enter".
5) Select the appropriate microcode image to flash by pressing "1".  (The image will end in 0422003f).  Press Enter.  Press Enter again to confirm.
6) If multiple devices were selected in step 4, then repeat step 5 until finished.
