Moving from vSphere 5.5 to vSphere 6.5 Part 1 #Upgrade #Migration #Fresh #vExpert #vSphere #VCSA

January 15, 2019 Bilal Ahmed 0

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 […]

VCSA 6.5 AD Lookup Issues #DNS #DIG #VMware #vExpert #VCSA #vCenter

April 26, 2018 Bilal Ahmed 0

So, I have been deploying a new 6.5 VCSA as part of my plan to move away from the current 5.5 deployments I am working with (a post for another time). During testing of this new deployment, I had a user come to me with a strange error. When they changed their AD password, they lost all access to the VCSA, but everything else for them worked fine, they could log in to anything else using their AD account. I could log into the VCSA fine and other users could still log in fine too. We cleared the web cache among other things, but to no joy. I couldn’t really see anything that was wrong. A few web posts mentioned that […]

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

March 29, 2018 Bilal Ahmed 0

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. Ref: ‘snapshot-401632’ [Soap] Reverting snapshot snapshot-401632 [16.02.2018 16:07:53] <01> Info [VimApi] RevertSnapshot, type “VirtualMachineSnapshot”, ref “snapshot-401632” [16.02.2018 16:07:53] <01> Error […]

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 […]

vCNS 5.5 to NSX 6.2.3 upgrade – vCenter Lookup Not connecting

June 29, 2016 Kim Bottu 1

Yesterday I performed a vCNS 5.5 upgrade to NSX 6.2.3. I did run into issues later on the day thanks to NTP, there is a small gotcha here even if you had set it up correctly! The environment: vCenter 5.5 VCSA + embedded SSO ESXi 5.5 vCNS 5.5 ( vShield Manager + vShield APP Firewalls) some VMs ( including DHCP and Domain Controller) NTP running from a Windows Server   Performing the upgrade of vCNS is pretty straight forward:   Download the NSX upgrade package: VMware-vShield-Manager-upgrade-bundle-to-NSX-6.2.3-3979471.tar.gz. Open the vCNS vShield Manager Go to Updates and Upload Upgrade Bundle After the upgrade you might end up with a web interface which looks like a mix of vCNS and NSX. Flush the […]
