5.0 To Determine Adapter Microcode Levels

Before installing the microcode, it is important to determine the current microcode level of the adapter.

5.1 AIX Systems

1.  List the Fibre Channel (FC) adapters installed in the system by typing on the command line:

lsdev-C | grep fcsX

Note the device names of all the fibre channel adapters installed. The adapter device names will be fcsX, where X is 0,1, or some other number. There will be an fcsX listing for each port of the FC EC23 adapter

2.  Determine the current microcode level on the adapter by typing on the command line:

lsmcode-d fcsX
where X is the number of the adapter's port returned from the "lsdev" command above.

A screen similar to the following will be displayed:

DISPLAY MICROCODE LEVEL                                                          802111

fcs0             FC 5052 2-port 16Gb FC Adapter  (df1000e2df1002e2)

 

The current microcode level for fcs0

is 00001000010004300012

 

Use Enter to continue.



F3=Cancel             F10=Exit             Enter

 

If the current microcode level is not 00001000010004300012, then the microcode image on the adapter is not at the latest level.

5.2 Linux Systems

1.  Identify fibre channel hosts. Following command will list fibre channel hosts.

ls /sys/class/fc_host

 

Example output: host3 host4

 

2. Verify firmware version running on the host.  The following command will display the firmware version loaded by the adapter, where host{n} is replaced by one of hosts listed in previous step.

cat /sys/class/scsi_host/host{n}/fw_version

 

Expected output: 5.06.05 (nnnn)   (nnnn) can be ignored

If version reported is not greater than or equal to 5.06.05, then the microcode image on the adapter is not at the latest level.

6.0 Install RPM Package

6.1 AIX RPM Package

Use this method to install the AIX RPM package on an AIX system. Note that the commands are case sensitive and must be entered exactly as shown, including file names. Installing the RPM places the binary file df1000e2df1002e2.00001000010004300012  in the /etc/microcode directory.

1. If the /etc/microcode directory does not exist, make a directory to receive the RPM format file. On the command line type:

mkdir /etc/microcode

2. Transfer the RPM format file, df1000e2df1002e2. 00001000010004300012.aix.rpm to any temporary directory on the target system.

3. Unpack the file. On the command line type:

rpm -ihv --ignoreos df1000e2df1002e2.00001000010004300012.aix.rpm

4. If the microcode package unpacks successfully, the microcode file will be added to the /etc/microcode directory.

If a message is received saying the "package <package_name> is already installed", you will need to uninstall the rpm package. On the command line type:

rpm -e <package_name>

where <package_name> is the name of the package that was returned in the message. Return to step 3 and attempt to unpack the file again.

5. Go to section 7.0 to complete the update.

7.3 Enabling Linux driver firmware load from flash

On RHEL6 and SLES11 Linux distributions, the firmware is loaded automatically by the qla2xxx driver  from the /lib/firmware/ directory. On RHEL5 the firmware is loaded by the qla2xxx driver from the driver image itself. If Standalone Diagnostics are used to update the adapter flash, then 

the qla2xxx driver must be set to load the firmware from the flash by specifying  qla2xxx driver parameter, ql2xfwloadbin. 

 

The steps required to set the ql2xfwloadbin driver parameter in a persistent manner varies by Linux release as described next.

 

RHEL5

 1) Using a Linux text editor, edit the file /etc/modprobe.conf

 2a) If there is a line in the file starting with options qla2xxx then add ql2xfwloadbin=1   to the end of that line.

 2b) If there is no line in the file starting with options qla2xxx then add a new line to the file, options qla2xxx ql2xfwloadbin=1

 3) Save the file

 4) Make a new initrd to include the updated qla2xxx driver options in the boot image.  On the command line, key in

    mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r)

 5) Reboot

 

 

RHEL6

1) Using an a Linux text editor, create a new file /etc/modprobe.d/qla2xxx.conf

2) Add this line to the /etc/modprobe.d/qla2xxx.conf file created in step 1,  options qla2xxx ql2xfwloadbin=1

3) Save the file

4) Save the file

 4) Make a new initramfs to include the updated qla2xxx driver options in the boot image.  On the command line, key in

    dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

 5) Reboot

 

 

 

SLES11 mkinitrd

1) Using a Linux text editor, edit the file /etc/modprobe.local.conf

 2a) If there is a line in the file starting with options qla2xxx then add ql2xfwloadbin=1  to the end of that line.

 2b) If there is no line in the file starting with options qla2xxx then add a new line to the file, options qla2xxx ql2xfwloadbin=1

 3) Save the file

 4) Make a new initrd to include the updated qla2xxx driver options in the boot image.  On the command line, key in

      mkinitrd

 5) Reboot

7.4 Using the Standalone Diagnostics CD

Below are references and the general flow on how to update microcode update via CD. This method requires

1) Boot the system via a Standalone Diagnostic's CD

a) To create a bootable Diagnostic's CD go to the following URL.

http://www.software.ibm.com/webapp/set2/sas/f/diags/home.html

b) 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 df1000e2df1002e2.00001000010004300012.aix.rpm file(s) and unpacking them on a usable server. The unpacked files can then be burned on to the CD media.

8.0 Verifying the Update

8.1 Verifying the Update on AIX

1.  List the Fibre Channel (FC) adapters installed in the system by typing on the command line:

lsdev-C | grep fcsX

Note the device names of all the fibre channel adapters installed. The adapter device names will be fcsX, where X is 0,1, or some other number. There will be an fcsX listing for each port of the FC EC23 adapter

2.  Determine the current microcode level on the adapter by typing on the command line:

lsmcode-d fcsX
where X is the number of the adapter's port returned from the "lsdev" command above.

A screen similar to the following will be displayed:

DISPLAY MICROCODE LEVEL                                                          802111

fcs0             FC 5052 2-port 16Gb FC Adapter (df1000e2df1002e2)

 

The current microcode level for fcs0

is 00001000010004300012

 

Use Enter to continue.



F3=Cancel             F10=Exit             Enter

 

If the current microcode level is 00001000010004300012, then the microcode image was updated successfully.
