Summaries

• ESXi 3.5 Update 4 hosts with Emulex HBAs might stop responding when accessed through vCenter Server.
• This patch reduces the boot time of ESX hosts and should be applied when multiple ESX hosts detect LUNs used for Microsoft Cluster Service (MSCS). 
• After applying this patch, any request for connection with ESXi 3.5 using cipher suite of 56-bit encryption will be dropped. This also includes any request for connection to CIM port 5989 on ESXi 3.5. As a result, browsers that exclusively use cipher suites with 40-bit and 56-bit encryption cannot connect to ESXi 3.5. Microsoft has made the Internet Explorer High Encryption Pack available for Internet Explorer 5.01 and earlier. Internet Explorer 5.5 and later versions already use 128-bit encryption. 56-bit encryption and below is considered weak encryption and should no longer be used.

• ESXi host fails if its available TCP/IP sockets are exhausted and an NFS Client has a directory mounted.

Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table, above.

Patch Download and Installation

ESXi hosts can also be updated by downloading the most recent "O" (offline) patch bundle from http://support.vmware.com/selfsupport/download/ and installing the bundle using VMware Infrastructure Update or by using the vihostupdate command through the Remote Command Line Interface (RCLI). For details, see the ESX Server 3i Configuration Guide and the ESX Server 3i Embedded Setup Guide (Chapter 10, Maintaining ESX Server 3i and the VI Client) or the ESX Server 3i Installable Setup Guide (Chapter 11, Maintaining ESX Server 3i and the VI Client).
