Problem SSH connection with ESX 4.1.0 348481 UPDATE 1 - URGENT !!

We have two ESX vSphere structures:

structure "A" -> with a vSphere 4.0.1
structure "B" -> with ESX version 4.1.0, 348481 UPDATE 1 (latest version available today)

We use Veeam Backup & Replication v.5 for backups of VM

- in the structure "A" I don't have problem
- in the structure "B" the phisical HOSTS don't see the physical storage connected to ESX (fiber channel and iSCSI).

In the structure "B" we have enabled the following:

1) Local TSM enable (see attachment "Structure B - Local TSM enable.jpg")
2) Remote TSM enable SSH  (see attachment "Structure B - Remote TSM SSH enable.jpg")

In the structure "B", I think that the problem may be with communication in SSH.
For example: if I use SSH with putty, I enter in the host but I can not see the folder as the "ssh", which should be inside the folder "etc"  (see attachment "new host - no show folder SSH.pdf")

In the old structure "A" attached, you see attachment "old host - show folder SSH - ok.jpg"
So, in I also notice that the prompt is "root@...", in the new structure "B" is different, but I use always the root account.

If I use Veeam also in the structure "A" (Structure A - show SSH connection TAG.jpg) appears TAG SSH connection, while in structure "B" this does not appear (Structure B - don't show SSH connection TAG.jpg)

I do not think is a problem of Veeam, I think it is a problem of physical configuration of ESX.

Is very urgent.

Thanks
