Does this happen to all your VM's or just this one?
If it affects all your VM's, possibly the CBT license file is not installed.
 
Otherwise suggest you open a ticket with Tivoli.
If it is only one VM, FWIW I have had a few Linux machines (they were not red 
hat) where VMware was never able to provide CBT information.

Hello

I have a vmware environment and I am using TSM for VE 6.4 for backup every new 
machine added to vmware I configure the Changed Block Tracking(CBT) to true  as 
ctkEnabled: True

The first backup I run for the virtual  machine even the CBT is ON I got the 
message:

05/29/2013 08:09:01 ANS9384W Unable to get VMware Changed Block Tracking(CBT) 
data for virtual machine 'mdb2'. Full VM backup continues, and includes both 
used and unused areas of the disk.

The problem is that we are using the feature of Thin provisioning by giving 
more disk capacity, so in my example:

Have a disk name : Hard disk 2    Provisioned Size: 1.6 TB

We have around 100GB data on this disk . but when running the first backup got:

Processing snapshot
        disk:         [netapp-moodle-4500] mdb2/mdb2.vmdk (Hard Disk 2)
        Capacity:     1,610,612,736,000
        Data to Send: 1,610,612,736,000
        Transport:     (hotadd)[sending]

I thought even is the first backup it will still backup only 100GB and not the 
full provisioned size 1.6T !

I miss obviously something ?
