Download Instructions

Download and verify the patch bundle as follows:

1.      Download patch ESX-1004721 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.
 
6.      Verify the integrity of the downloaded tar file:
 
# md5sum ESX-1004721.tgz

The md5 checksum output should match the following:

48190819b0f5afddefcb8d209d12b585 ESX-1004721.tgz
 

7.      Extract the compressed tar archive:

# tar -xvzf ESX-1004721.tgz

8.      Change to the newly created directory, /var/updates/ESX-1004721:

# cd ESX-1004721

Installation Instructions

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-1004721 update

For example, if the host is called depot:

# esxupdate -r file:///depot/var/updates/ESX-1004721 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-1004721 update

For more information how to use esxupdate, see the Patch Management for ESX Server 3 tech note at http://www.vmware.com/pdf/esx3_esxupdate.pdf .
