How to update the Disk firmware on Exalytics systems

Solution

To update the firmware on disk drives installed in an Exalytics server the following steps should be followed.

First confirm the type of disks installed and determine the needed firmware patch.
Using the MegaCli64 command we can display the model information for all installed disks.
In the following example we use grep to just display the Enclosure, Slot, Disk Model and Firmware Level information. This is the information we will need to determine the patch number and to apply the firmware. If the firmware level shown already matches the latest version available then there is no need to perform the update steps.

The output above shows that the system has Hitachi H109090SESUN900G drives installed.
After determining the disk model information from this output reference the following list to find the patch number that contains the latest firmware image.

Download the patch from MOS and transfer it to the Exalytics system. change directory to the directory with the patch download and unzip it, for example:

Next cd to the megaraid directory of the patch and execute the bitops.sh script.

The Exalytics system image may not have the ksh shell available in the location expected by the script. If not you will see the following error when attempting to run the script

If this error is seen then edit the script using vi (or your favorite text editor) and change the very first line to use /bin/sh instead of /usr/bin/ksh. After editing the first line should be:

After editing the file run the script again, it should execute without error (it will not provide any output). This script will create the needed .fw files in the megaraid directory. Use the ls command to list the new contents of the directory to find the proper .fw file for your disk model.

In our example we have Hitachi H109090SESUN900G drives so we will use the file "H109090SE.A720.fw"

We are now ready to apply the firmware using the "MegaCli64 -PdFwDownload" command, the following options are used.
The disk to be updated is indicated using -PhysDrv[enclosure:slot]  The enclosure and slot numbers are obtained from the initial disk list command at the top of this document
The firmware file is provided using the -f flag.
-a0 indicates the controller in use (for Exalytics this will always be -a0)
So to update the Hitachi H109090SESUN900G drive in Enclosure 252, Slot 0 we use the following command

 If there are several of the same disk model installed to be updated you may update multiple disks in one command line by listing the disks separated by a comma. The following example shows a command that updates the disks in slots 0,1,2,3,4 and 5 (all within enclosure 252).

Note: for the Exalytics X5-4 the system uses a SAS-3 controller so the "storcli64" command may also be used for the above commands. The syntax will be the same and the command is located here: /opt/MegaRAID/storcli/storcli64
