NetBackup 10.0 earlier version did not support Instant Access with VMware vSphere 7.0 U1, 7.0 U2, and 7.0 U3,
is there a solution now?
From this document " Veritas NetBackup ™ Enterprise Server and Server 10.0 - 10.x.x
OS Software Compatibility List" is possible see that there is an EEB, to Instant Access with Vmware that can be obtained from Veritas Support, see below.
