This caused SAS Fabric errors and the SAS expanders to reset in an alternating fashion. -Fix for LED issues including those caused by Fan failures, A/C power chord removal. -Fix for Queue Full response being returned to the SAS adapter. This issue gets reported as a SAS_ERR3 or VRSAS_ERR21PD -Fix for PLD test cases causing a hang condition of the SAS expander -Minimum link rate set to 3.0Gbps 6795 -GA level for FC EDR1 NOTE: "lscfg -vl sasdrawer" VPD will not show Power Supply information IF 5888 ses is updated to 6795 code level WITHOUT updating to AIX levels corresponding to Oct 2012 releases AIX 61 TL5 SP9 AIX 61 TL6 SP9 AIX 61 TL7 SP5 AIX 71 TL0 SP7 AIX 71 TL1 SP5 6695 -GA level * 2.0 General Information* * 2.1 Installation Time:* Approximately 30 minutes *2.2 Machine's Affected:* FC 5888, EDR1 * 2.3 AIX Requirements:* 5888 support: 6.1 TL5 SP8 6.1 TL6 SP7 6.1 TL7 SP4 7.1 TL0 SP5 7.1 TL1 SP4 or above EDR1 support: 6.1 TL5 SP9 6.1 TL6 SP9 6.1 TL7 SP5 7.1 TL0 SP7 7.1 TL1 SP5 * 2.4 Linux Requirements:* For 5888 & EDR1 support: Red Hat Enterprise Linux 5.8 for POWER, or later Red Hat Enterprise Linux 6.3 for POWER, or later Novel SUSE Linux Enterprise 11 Service Pack 2, or later *2.5 IBM i Requirements:* IBM i 7.1 * 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 SES installed in the system by typing: lsdev -C | grep ses Note: All of the SAS RAID initiators addresses that are installed will be displayed. The names will be sesX, where X is 0, 1, etc. 2) To check the current microcode level for the adapter or controller enter the following command lscfg -vl sesX Where X is the number/s of the previous command. The Command will produce output similar to * DEVICE LOCATION DESCRIPTION* ses5 U5888.001.H23C002-P1-C2 SAS Enclosure Services Device SAS Expander: FRU Number..................74Y9685 Serial Number...............YL10JH23C003 Customer Card ID Number.....57C3 *ROM Level.(alterable).......6675* Hardware Location Code......U5888.001.H23C002-P1-C2 If the *ROM Level and ID* is less than *67G5* then update the microcode. * 3.1 Determine the Current Microcode Level for Linux:* 1) Type "iprconfig" 2) Select "Display hardware status" 3) Select SES by typing a "1" in front of it and pressing Enter. 4) The Command will produce output similar to "*Firmware Version . . . . . . . . . . . . : 6675*" If the *Firmware Version* is less than *67G5* then 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) "*ses.5888-67G5-1.aix6.1.noarch.rpm*" B) "*ses.5888-67G5-1.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 ses.5888-67G5-1.aix6.1.noarch.rpm" 5b) For Linux: Unpack the RPM file by using the following command: "rpm -ihv --ignoreos --force ses.5888-67G5-1.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: 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 *ses.5888-67G5-1.aix6.1.noarch.rpm * B) For Linux: The filename is * ses.5888-67G5-1.Linux.noarch.rpm *3) Unpack the file by executing the instructions below: A) For AIX: Type "*rpm -ihv --ignoreos --force ses.5888-67G5-1.aix6.1.noarch.rpm" * B) For Linux: Type "*rpm -ihv --ignoreos --force ses.5888-67G5-1.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 Discovery Tool Microcode CD-ROM creation and download instructions* To obtain information how to burn a CD-ROM and run the Discovery Tool for an AIX System please go to: http://techsupport.services.ibm.com/server/mdownload/CDROMhelp.html 1) After running the Discovery Tool successfully the "/tmp/microcode/RPM" directory was created and your rpm files are copied from the CD-ROM. 2) Change to that directory, "cd /tmp/microcode/RPM". 3) Unpack the file by executing the instructions below: Enter the commands: *rpm -ihv --ignoreos --force ses.5888-67G5-1.aix6.1.noarch.rpm* 4) Microcode files will be copied to "/etc/microcode". The file size and checksum of the microcode image will be verified in Section 5.0 *Notes:* - "/etc/microcode" is a symbolic link to "/usr/lib/microcode". - If permission does not allow the copy to the above stated directory or file then the user will be prompted for a new location. * 5.0 Verifying microcode before download and notes* *NOTE:* Microcode download must be performed separately for each "ses" 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. /Installation Time: /Approximately 30 min System Time. Please verify the file size and checksum of the raw microcode files matches the below.* **Filesize: 1125260* *Checksum: 38057* For AIX: "ls -l /usr/lib/microcode/A1700DF0.67G5" to verify Filesize. "sum /usr/lib/microcode/A1700DF0.67G5" to verify Checksum. For Linux: "ls -l /lib/firmware/IBM-A1700DF0.67G5" to verify Filesize. "sum /lib/firmware/IBM-A1700DF0.67G5" to verify Checksum. For systems that have LPAR installed, the microcode file must be placed on all partitions that have a SES 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 A1700DF0.67G5" 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 IBM-A1700DF0.67G5" F) Type: "quit" * 5.1 Microcode Download Procedure-**SAS Enclosure Services for FC 5888 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 Enclosure Services for FC 5888s that need to be updated from the list of devices by pressing "Enter". The devices will be displayed as ses#, 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 ses# 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 67G5 by typing "lscfg -vl ses#" for each SES device updated. *5.2 Microcode Download Procedure-SAS Enclosure Services for FC 5888 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 Enclosure Services for FC 5888s that need to be updated from the list of devices by pressing "1".
