SAN team would be the one who can tell you how many LUNs are assigned to the VM environment and also the Backup host.
then compre the LUNs IDs and see if the required once are mapped or not.
diskmangement or diskpart will give you the number of disks and disk ID that are avalaible on the backup host.
if you what to see the LUN ids on the backup host, check with your SAN admin to find the tool for that..
as i said for EMC its powerpath not sure about the HP 3PAR

ERR - Error opening the snapshot disks using given transport mode: Status 23
so what is the transport mode that you are using to take the backup?
does it SAN or NBD?
if it is SAN , did you mask the all LUNs to backup host?
if it is NBD, does backup able to communicate with the ESXi with 902 port?

- I'm using NBD e SAN
- if it is SAN , did you mask the all LUNs to backup host?
Yes
if it is NBD, does backup able to communicate with the ESXi with 902 port?
I do not know how do I test the port 902?
01-03-2014 10:38 AM
telnet <esxi hostname> 902
from the backup host will check if the communication is fine or not. it that is not connected you need to fix the network communication issue to work over the NBD method.
did you select both transport methods in the policy?
for test , select only one tranport mode may be SAN and try the backup again.
please create the bpbkar log dir in backup host and enable the log VERBOSE To 5 and then try the backup
once the backup got failed attach the bpbkar log to this post.

How do I check if all Luns are available for the backup host?
01-03-2014 11:23 AM
you can check the LUN avaliablity on the backup host on Disk management
and also in DIsk part
but those will not give you the LUN IDs.
what is the storage that you are using? based on the storage you can install the application to namage it
for example if you have EMC storage --> powerpath software would able to provide the info about the LUN IDs and disk numbers in OS

So Do you see disks on the disk management?
els run the below command in Command prompt to list the disks
diskpart Diskpart> list disk

Lun was created in HP 3PAR and was made available to the host Backup.
