I am working on a government contract where our customer requires us to use IPv6 in as many places as possible. I recently discovered that our NetBackup 7.6.0.1 will not communicate with our vCenter server over IPv6 while performing a VMWare backup. A tcpdump showed that NetBackup needs IPv4 for taking VMWare snapshots (there might be more IPv4 dependencies).
I opened a support ticket with Symantec, and the service rep. said that it's the VMWare API for vCenter that doesn't support IPv6. Would it be possible to put pressure on VMWare to support IPv6 so that NetBackup can also support it?
