So I have been meaning to write a post on this for a while, so I thought I better get started! So let me tell you a story! The Beginning  Now as we all know vSphere 5.5 went EOL a little while ago. So in preparation, I was investigating the various options that were available for the business, to keep them supported. When I first joined the business years ago. it was all a vSphere 5.1 environment that didn’t get patched often and hosts had very very long uptimes. the reason I was brought on board was to get a handle on this and bring it all into line. One of the first jobs was to actually re-ip the whole environment […]

Storage vMotion Thin to Thick Lazy Scripting #vExpert #PowerCLI #PowerShell #vSphere

Well hello, there party people! I recently came across an issue where the customer had just configured alerting to look for Thin Provisioned VMs, and to my and their dismay it came back with over 300 VMs across 2 sites in staging and production that were like this. Now they have Dell Compellent SANs and these Thin Provision at the storage layer too, so it was basically thin on thin! Now the key points here were: Let’s figure out why this happened Let’s fix the issue for the currently deployed VMs and for future deployments Now we did some digging and it appears the Devs and their automation scripting were the cause of the issue. In their scripts, they had it […]

Veeam Restore Issue #VEEAM #BACKUPS #vEXPERT #VMware #vSphere

So recently I came across an issue where Veeam would restore from a backup and it would be marked as successful, but when you went to power the VM on it would fail with a CID mismatch (of course you can fix this manually by messing around in the vmdk files, but you shouldn’t need to do this). On closer inspection of the restored VM, you would see that the VEEAM RESTORE SNAPSHOT was still in place. In the restore logs I noticed : Create snapshot, ref “vm-401631”, name “VEEAM RESTORE SNAPSHOT”, description “”, memory “False”, quiesce “False” [16.02.2018 16:01:37] <01> Info [Soap] Snapshot VM ‘vm-401631’ was created.

ERROR vCenter 5.5U2 upgrade to vCenter 6.0U2a: 1603, A change must be made to this systems time and many others

March 3, 2017 Kim Bottu 0

Recently I had several problems upgrading vCenter server 5.5U2 to vCenter server 6.0U2a. Luckily all has been solved now and I owe a huge thank you to  Ciaran McE from VMware Support who has stood by me and helped me to solve this vCenter upgrade problem. Below I am listing a handful of the errors we have seen, how you can spot them and how you can solve them. Error 1: Error 1603. Because SSO appeared to be somehow corrupt [As a test to check if SSO was intact I deleted of a local SSO group resulted in the unavailability of SSO as a whole], I had to install a new external SSO server,  remove and reinstall vCenter server and re-point […]
