I need to integrate an appliance 3.0 (SUSE ) with vsphere 5.1 is this possible on NBU 22.214.171.124?
Not possible with NBU 7.1.x - you need to be on NetBackup 126.96.36.199 or later.
Please see Statement of Support for NetBackup 7.x in a Virtual Environment: http://www.symantec.com/docs/TECH127089
Look for these topics in the doc:
Supporting Storage Foundation and VCS on Unix and Windows as well as NetBackup on Unix and Windows
Handy NBU Links
