We recently upgraded to Vmware Esxi 6.5 for our hosts which host a bunch of VM's that I backup. Before that we were on Esxi 5.5. Prior to the upgrade the vm backup was running without any issues, however post upgrade none of them seem to be working and fail with the message "error opening snapshot disks using given transport mode status 23". I have tried using different transport modes but no luck. Updated the host file entries on my master server to point to the correct Esxi host, still no luck.
What I wanted to check was before going any further is that ... Is Netbaclup version 7.6 compatible with backing up virtiual machines on host with the version of 6.5? I know this version of netbackup is really old and end of support life, but I wanted to know if there some kind of matrix from Veritas which says .. using this version of netbackup (7.6).. you wont be able to backup vm's on Esxi version 6.5...
PS: Yes, i know we need to upgarde our NBU version!
