Symptoms

On UNISYS platforms the Option ROM (OP-ROM) of only the boot adapters are enabled. So when an adapter controlled by the megaraid2 driver is installed as a non-boot adapter on UNISYS platforms, the card initialization might fail during driver load, causing the ESX Server host to become unresponsive.

Deployment Considerations

• The megaraid2 driver.
• All I/O cards managed by the megaraid2 driver.

Download Instructions

Download and verify the patch bundle as follows:

1. Download patch ESX-1002957 from http://www.vmware.com/download/vi/vi3_patches.html .

2. Log in to the ESX Server service console as root.

3. Create a local depot directory.

# mkdir -p /var/updates

Note: VMware recommends that you use the updates directory.

4. Change your working directory to /var/updates .

# cd /var/updates

5. Download the tar file into the /var/updates directory.

7. Extract the compressed tar archive:

# tar -xvzf ESX-1002957.tgz

8. Change to the newly created directory, /var/updates/ESX-1002957 :

# cd ESX-1002957

Installation Instructions

Note: All virtual machines on the host must be either shut down or migrated using VMotion before applying the patch. A reboot of the ESX Server host is required after applying this patch.

After you download and extract the archive, and if you are in the directory that you previously created, use the following command to install the update:

# esxupdate update

To run esxupdate from a different directory, you must specify the bundle path in the command:

# esxupdate -r file://<directory>/ESX-1002957 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1002957 update

During the update process, logs appear on the terminal. You can specify the verbosity of esxupdate logs by using the -v option as shown below.

# esxupdate -v 10 file://<directory>/ESX-1002957 update
