vSphere Patch released to resolve APD errors

Finally VMware have patched the problem with the previous vSphere update that ended up causing All Paths Down errors with NFS storage which I blogged about here: https://thevirtualunknown.wordpress.com/2014/04/24/intermittent-nfs-all-paths-down-on-esxi-5-5-u1-upgrade/

ESXi 5.5 Express Patch 04 has resolved this issue and so any customers with NFS storage should be able to safely patch their VMware environment to resolve the OpenSSL Heartbleed vulnerability without fear of losing their storage connectivity! =)

For more information about the patch, visit the KB: http://kb.vmware.com/kb/2077360

VMware have also released an update to vCenter Server to address a few issues. For more information about this update, have a look at the release notes: https://www.vmware.com/support/vsphere5/doc/vsphere-vcenter-server-55u1b-release-notes.html

Resolving OpenSSL Heartbleed for ESXi 5.5

Following on from my previous blog I realised that I didn’t actually put up the KB to explain how to patch ESXi 5.5 to combat the Heartbleed vulnerability.

Detailed instructions on the patches required and how to re-mint the Open SSL certs can be found on the following KB:

If anyone is concerned about the OpenSSL Vulnerability that was highlighted earlier this month, then pop along to the Security Advisory below:


Updates for the majority of VMware products to combat the “Heartbleed” vulnerability is now available….. Please note that post upgrade of products, you will need to regenerate the OpenSSL certificates!
