Regarding V- Storage Backup

Created: 03 Dec 2012 | 7 comments

Hi All ,

 

In NBU 7.0.1 when we trying to configure the V - Storage backup , is it required that backup host (Media Server ) need to reach (ping) the Virtual machine ,if I am adding a new Virtual Machine in my backup environment  which is lying into a different subnet as compared to our Backup Host or Media server, and these server   is not able to reach that Virtual Machine, the Storage mapping of the LUNS is already done by me and the LUNS on which Virtual machine is hosted is visible to the backup host but still my backup is failing with error code 13

Wondering way you configured backup is not True Vmware backup. It has to be agentless backup except if GRT is required.

NBU has nothing with guest VM ip and physical hypervisor IP.. It only communicates with Physical system (Backup host) to get list of VMs by inventory and asks Vmware to provide snapshot , which further is backed up and same is requested to delete upon successful completion. IT'S VMWARE how it handles snapshot. though NBU can help by next run (stun cycle) to remove orphaned snapshots if any)

Check if any ports are not getting blocked in between causing this failure.

How does NBU access VM inventory, is it via vCenter server or ESX? Make sure that NBU backup host is able to connect with vCenter or ESX host.

As Jack's comment, its not required that each VM has to connect to NBU backup host.

Hi Rizwan ,

We are using V-cente to access the VM inventory , could you please let me know which port I need to check for this issue ,

Regards,

Rohit

For vCenter, its 443 (TCP). Check if the the crediention validation suceeds for your vCenter.

hi Rohit

 

Did you went through VMware Guide (Better go through it, it would answer all your queries)

You use vCenter for VM inventory ( but for whose purpose do you inventory it, NBU or for operational purpose)

Within NBU is vCenter configured as VMware Acccess/Backup host?

Did you specified credentials for ESX/vCenter server to let NBU get connected with same and browse all the VM guests within?

Refer Abdul's blog series which gives insight for Vmware transport methods and ports used

 

btw For discovery it uses 443 port and for NBD it uses 902 port

 Cheers !!!

HI All ,

 

Facing the below issue only for one VM , that Machine hosted on the Same ESX host managed by the same VC server on which rest of my VM is also configured , So I really don't think its a port issue .

Regards,

Rohit

What happens, when you delete and re-add the VM in the policy?
