Host update fails after updating to 4.1u2

After updating vCenter Update Manager (right after updating my vCenter Server) from 4.1u1 to 4.1u2, I received the following error when trying to update on of my hosts:

Remediation did not succeed for esxihost: SingleHostRemediate: esxupdate error, version: 1.30, operation: 7: ('http://esxihost:9084/vci/hostupdates/hostupdate/vmw/vibs/cross_oem-vmware-esx-drivers-net-vxge_400.2.0.28.21239-1OEM.vib','/var/tmp/cache/-1699692350','[Errno 14] HTTP Error 404: Not Found')

After doing some research, I discovered what happened is that Update Manager 4.1u2 is case sensitive, whereas 4.1u1 was not. Any patches that were downloaded previous to the 4.1u2 update that contain upper case letters will fail with this error. VMware has a KB article about it here.

The patches affected are the ones below. I've put the correct capitalization on them for you. If you go to your patch repository, you can rename the files that you have to the below, and you should then be able to update your hosts. The repositories are located here:

• Windows2008: C:\ProgramData\VMware\VMware Update Manager\Data\Hostupdate\vmw\vib\
• Windows2003: C:\Documents and Settings\All Users\Application Data\VMware\VMware Update Manager\Data\Hostupdate\vmw\vib

Syslog not configured on ESXi 4.1u2

When I updated my ESXi host from 4.1u1 to 4.1u2, I got the following error message:

Configuration Issues
Issue detected on esxihost in datacenter: Warning: Syslog not configured. Please check Syslog options under Configuration.Software.Advanced Settings in vSphere client.

I thought it was odd since the host previously never complained about the Syslog before. I compared the settings between it and the other 4.1u2 hosts that I had, and indeed, it was missing the Syslog.Local.DatastorePath setting.

The setting on my hosts was:
[] /scratch/log/messages

Once I copied this into my Syslog.Local.DatastorePath setting on the server, it was happy. I went ahead and copied the setting to my remaining 4.1u1 servers so that they will be happy when updated as well.

So apparently ESXi 4.1u2 has issues with the Syslog running on ramdisk, but ESXi 4.1u1 doesn't.

I found the following VMware KB Article that explains why it complains about it:
Syslog not configured messages on ESXi host console or in logs

Installing PowerCLI on Server 2008

In attempting to install VMware vSphere PowerCLI on Windows Server 2008 x64, the following error comes up. This also happens on Server 2008R2.

Error 1406. Could not write value InstallPath to key \Software\VMware, Inc.\VMware vSphere PSDK Runtime. Verify tha tyou have sufficient access to that key, or contact your support personnel.

The prescribed fix for this is to remove the following registry key (and subkeys):
HKLM\Software\Wow6432Node\VMware, Inc.

*** Please make sure you know what you are doing in the registry before you do anything in there!!!

After that, installation proceeds successfully.

The only thing under the VMware, Inc. registry key is a "volatile" key with a UUIDHost DWord under it. Since I don't like to mess with other programs installed on the server (the one I was using has Quest vRanger installed), I exported the key, removed it, installed PowerCLI, and the imported my volatile key back in.

ESXi Host Unable to Update

I had a VMware ESXi 4.1 host that I was unable to update/patch using Update Manager the today.

It was coming up with the following errors when I tried:

VMware vCenter Update Manager had an unknown error. Check the Tasks and Events tab and log files for details.

And when I did that, I found this:

Could not install patches on esxihostname
Remediation did not succeed for esxihostname: SingleHostRemediate: Install error on host: esxihostname, error details: vim.fault.NoHost.

So I did some quick googling, and ran across this website that had the answer I was looking for.

The particular host that I was trying to update did indeed have an Unknown (inaccessible) VM on it (left over from yanking the storage and being sloppy...). I removed the VM from inventory, then was able to successfully patch the host.
