I’ve been upgrading all the various components in my lab from vSphere 5.1 to 5.5. Everything had been going smoothly, I upgraded the vCenter Appliance to 5.5 without issue. The first problem I’ve come across, was trying to perform an ESXi 5.1 host upgrade. They are both virtual but this isn’t the root cause. Funnily enough, the first host upgraded to 5.5 as expected via Update Manager, the second host failed with the following error in vCenter:
In order to fix my issue (your mileage may vary), I ran the following commands on ESXi via SSH (Putty).
- cd /bootbank
- cd /altbootbank
- ls -l
- cd state.xxxxx
- ls -l
- mv local.tgz ../
After this, I proceeded with the remediation of the host from Update Manager, and the upgrade to ESXi 5.5 was successful.
