Dell Bootable Firmware Update ISO - is invalid

Today I hit a bit of a speed bump during some ESXi host upgrades. I like to roll out firmware upgrades while I’m upgrading ESXi, and some Dell M620’s decided they didn’t want to play ball. I was using the Dell Bootable Firmware Update utility available here. While the ISO was in fact bootable, none of the scripts or inventory collectors were able to run. Repeated attempts to mount the virtual CDROM would fail, followed by this message:

Updating a Route53 domain's Name Servers

I recently had the need to update an AWS Route53 domain NS configuration so that it could be protected by CloudFlare. This domain was purchased via Route53. I had updated the hosted zone NS records with the new Name Servers, but the domain continued to point to AWS and it drove me nuts. Turns out there is another section in Route53 where you updated the NS records for your Route53 managed domain.

VCAP6-DCV Design certification achieved!

After months of studying and a Design and Deploy course for good measure, I passed the incredible VCAP6-DCV Design exam! This certification in combination with my VCAP5-DCA from 18 months ago has awarded me the VCIX6 title which I’m incredibly proud of. Here’s the official link from VMware about the certification: To give you an idea of what the Design exam is about, take a look at www.

CA-signed vCloud Director certificates no longer trusted – SAN missing

Hello again! Today’s adventures drove me a little wild… Some background first. In my test environment, I have a full vCloud Director v8.10.1 deployment, load balanced with an F5 LTM. The certificates are loaded on the F5 so that traffic is terminated and re-encrypted on it’s way to the vCloud cells. Since deployment, both the http and console FQDNs functioned as expected. This all changed just a few months ago…

PSC 6.0U3 not respecting certool.cfg settings when generating VMCA CSR

After a very successful and quick migration from Windows SSO 5.5 U3e installation to a Platform Services Controller v6.0U3 appliance I was ready to get my VMCA into action. We have a corporate internal Microsoft CA with the VMware certificate templates already created as per VMware KB 2112009. Everything was coming up Milhouse, until CSR generation time using the ‘certificate-manager’ on the PSCs. After stepping through the ‘certificate-manager’ wizard and having the CSR and private key files sent to a directory of my choosing, I quickly inspected the CSR using openssl to make sure I was on the right track:

Empty inventory after SSO v5.5 to PSC v6.0 U3 migration

After performing the vSphere v5.5 to vSphere 6.0 migration in our testing environment with great success, I began work on our production environment. First things first, migrating Windows SSO to PSC appliance. I had successfully converted the first machine, and started doing some testing. Things like logging into the thick client and checking all vCenter servers and basic login services. Problem Out of 6 vCenter servers, only 1 was having issues.

SYSTEM_REFRESH_VIMSERVER – Could not register vCloud Director as an extension to vCenter Server

While trying to troubleshoot another problem, we tried Refreshing vCloud to vCenter which includes registering/updating the extension. This is when we hit a beauty we’d never seen before: Alright, calm down. Probably something with the network, right? And if it’s not the network then it’s probably DNS. Right? Oh how I wish that were so. I dug around in the vCenter MOB and found the vCloud Director extension.

‘java.lang.NullPointerException’ received when modifying objects in vCloud Director

Roughly 2 weeks ago one of our vCloud Director tenants reported an error when attempting to increase a disk on their VM. They were told to contact their cloud administrator (yay). When we tried to perform the increase, we received an error we’d never seen before: “java.lang.NullPointerException”. Here is what we checked: Confirm the tenant Org vDC has the appropriate resources available (this was an ‘Allocation’ style vDC).

vSphere 6 certificate templates with SHA256 encryption

I was just in the middle of configuring a PSC 6.0 node’s VMCA as an intermediate CA and, in traditional fashion, went to request a certificate from a Windows Server 2008 R2 Microsoft CA using the web enrollment form (as per this VMware KB article). Oddly enough though my brand spanking new vSphere 6.0 machine and intermediate CA certificate templates were missing from the template selection drop down. I had a look around online and found that MS CA v3 certificate templates are not supported in the web enrollment form.

Update Export Failed – Converting Windows SSO to PSC Appliance

This isn’t a be all and end all post on converting your Windows-based SSO server to the Platform Services Controller appliance, although I found an issue when performing the migration. We kept receiving an “Update export failed” message when the appliance was deployed by the conversion wizard. We couldn’t understand why, and the appliance updaterunner.log file gave us no clues as to what it could be. Turns out, you must run the vcsa_setup.
