In the last post about upgrading ESXi 6.0 to ESXi 6.5, I showed you How to upgrade ESXi 6.0 to ESXi 6.5 using esxcli and How to upgrade ESXi 6.0 to ESXi 6.5 using Interactive Installer. In this post, I will show you how to upgrade ESXi 6.0 to ESXi 6.5 using VMware Update Manager.
Quite recently I had to do emergency ESXi patching due to the fact that one of the servers crashed at night for unknown reason. Troubleshooting and log analysis pointed to outdated firmware and drivers of HBA and NIC’s. In order to do driver update I quickly created baseline in vSphere Update Manager (VUM) and I would like to quickly show you how I did it.
With this post, I am starting series of articles about upgrading VMware ESXi to version 5.5.
Once we successfully installed vCenter Server 5.5 it is time to enhance its functionality by installing VMware vSphere Update Manager.
In short words, Update Manager is used to automating patching of VMware hosts. It is really simple yet powerful tool - it allows you easily update your whole infrastructure with zero downtime (if all done properly 😉 ).
Today I was working on problem related to VMware Update Manager pointing to wrong database and I managed to find the solution to this problem.
In my case SQL server was running on Windows Server 2008 R2 so I had to check 32 bit DSN located in %SystemRoot%\syswow64\odbcad32.exe
Of course DSN was pointing to correct database on correct DB server but VUM was still not working. Also it is important to mention that two days before vCenter Server was migrated from one host to another with vCenter Server version upgrade. I knew previous SQL database names so I knew what I was looking for. On new SQL server I created new databases - the one which was VUM referring to.
