 How to Update HDD Firmware on VCA (Virtual Cloud Appliance) and PCA (Private Cloud Appliance) Management and Compute Nodes per Doc ID 2076283.1

Solution

This document shows how to check and upgrade the HDD firmware on PCA management and compute nodes.

For example, the process shown below shows how to upgrade both management and compute nodes to HDD FW A720.

Overview of the process

Details

1. Download the patch from MOS

From MOS, download patch the patch and save in /tmp on the management node master.
This example uses HDD firmware patch ID 150940-04.

2. Unzip the patch in /tmp and backup the bitopts.sh file as shown below:

Next, edit the first line of bitops.sh file

Next, run the bitsop.sh file.  It will create the firmware files.

3. Copy the HDD firmware onto the shared storage.
Take note of these firmware filenames, you will need them later when you update the management nodes.

4. Check compute nodes

The following command will list the IP addresses for all compute nodes in the rack.

For each node, ssh into the ILOM first, and from there start the serial console into the node.
To determine the ILOM IP address, add 100 to the node IP address shown in the output above.
For example, ovcacn08r1 shows the node IP address is 192.168.4.10.  Adding 100 gives the ILOM IP address which is 192.168.4.110. 

For each node, do the following:

Check the disk type:

 Check the current firmware revision.  Shown below is firmware A6C0:

 Check the Enclosure ID.  (Should be 252)

 Check the disk slots (Should be 0 and 1)

 If the firmware needs to be updated, mount the shared_storage location and copy the HDD firmware into /tmp:

After the node has been placed in maintenance mode, reboot it into single user mode.

  
Wait for the system to start and complete POST

 
Wait for the LSI BIOS to start

 Note: You can also see the HDD firmware revision listed in the LSI output above. 

Continue to wait for the GRUB menu.  Before the 3 second timeout, stop GRUB from auto booting.
For example, press the down arrow key.  When GRUB is successfully stopped, you will see this screen:

  
Make sure the first line is highlighted, then press the 'e' key
Highlight the line with module /vmlinuz-xxx...xxx
In this example, it is the third line that contains "module /vmlinuz-2.6.39-400.249.3.el5uek"

  
When the correct line is highlighted, press the 'e' key.

Append the text " earlyprintk=xen single" (without the quotes) to the end of the line.

Before:

  
After:

  
Press the ENTER key which will take you back to the previous screen:

  
From here, press the 'b' key to boot.
Wait for the node to boot into single user mode.

Perform the firmware update.
For example, for the H101212SESUN1.2 HDD in slot 0 in enclosure 252:

 For the other disk, the H101212SESUN1.2 HDD in slot 1 in enclosure 252:

 Verify the HDD firmware has been updated:

Reboot the node and wait for the login prompt.
This will take several minutes as the node will go through POST and you will see the LSI BIOS start.
Do not interrupt it when the GRUB menu shows -- it will auto boot.
Wait for the OS to start until you see the login prompt, this will also take several minutes.

Stop the serial console and exit back to the ILOM.
Use the key sequence you took note of earlier in this process.
It should be ESC (

Exit the ssh to go back to the management node

 
5. Check management nodes

Update the HDD firmware on the non-master node first.

ssh to the ILOM on the non-master node:

Start the SP console and login as root:

In step #3 above, you took note of several firmware file names.
Copy them now from shared_storage into /tmp

Bring the node to run level 1

Check the disk type:

 Check the current firmware revision.  Shown below is firmware A6C0:

 Check the Enclosure ID.  (Should be 252)

 Check the disk slots (Should be 0 and 1)

 Next perform the update(s) as needed. 

For the H101212SESUN1.2 HDD in slot 0 in enclosure 252:

 For the H101212SESUN1.2 HDD in slot 1 in enclosure 252:

 Verify the HDD firmware has been updated:

 Reboot the node

 Lastly, from the non-master node, ssh into the ILOM on the master and repeat the process.

 Note:  Don't forget to copy the files from shared_storage into /tmp before you run the "init 1" command.

6.  Clean up as needed.

After the firmware on all HDDs have been successfully upgraded, you can delete the firmware files you placed in shared_storage.
