[NBU35]

Master & Media  Solaris 10, NBU 7.6.0.3

Backup hosts : Win 2008, NBU 7.6.0.3

VM backups of some clients are intermittently failing, I found following message in detailed job logs:

25/02/2015 07:33:24 - Info bpbrm(pid=11528) INF - vmwareLogger: SOAP 1.1 fault: "":ServerFaultCode [no subcode]    
25/02/2015 07:43:56 - Critical bpbrm(pid=11528) from client Client_name: FTL - VMware_thaw: Unable to unlock virtual machine: Client_name.

25/02/2015 07:43:57 - Critical bpbrm(pid=11528) from client Client_name: FTL - snapshot delete returned status 1    

as per TN:  http://www.symantec.com/business/support/index?page=content&id=TECH214208

I checked Roles of Vspehere account used for VM backups, it already has this permission "Register".

Still issue is there..

Any suggestions ?

does it create any issue permissions of unregister & update under EXTENSION are also given ?

Because as far as I have observed this account has all admin permissions for Vspehere..

[Marianne]

Sorry... No idea as I am not a VM admin.

I simply hand the TN to VM admins...

[NBU35]

Ok.. But I got to know this ROle has all permissions on Vsphere ..still backups locking the machines & corrupting the machines.
