Trying to use VUM 5.5 u2b to upgrade a ESXi 5.0 host to 5.5 U2. The following error appears in vCenter.
Cannot run upgrade script on host.
** NO DESCRIPTION FOR: com.vmware.vcIntegrity.RemediateTask
Other ESXi hosts in the cluster upgraded without an error (proving the 5.5 media uploaded to VUM was fine)
I followed VMWare KBA http://kb.vmware.com/kb/2007163
cat vau.log | grep error
I found the following error in vua-4.log – IOError: [Errno 2] No such file or directory: ‘/altbootbank/boot.cfg’
I tried up the upgrade via VUM again and failed with the same error in vCenter. Same ‘/altbootbank/boot.cfg’ in the vua log file. The thought is auto-backup.sh failed to copy the boot.cfg file so try by hand.
I copied /bootbank to /altbootbank via the command: cp -avr /bootbank/ /altbootbank
SUCCESS! I tried the upgrade via VUM one more time and it worked!
My backup plan was to download the depot.zip file of the 5.5 media, upload to a datastore and install via CLI.
esxcli software vib install -d /vmfs/volumes/datastore_name/VMware-ESXi-5.5.0-Update2-2403361-HP-522.214.171.124-Mar2015-depot.zip
