VDP disk expansion in VDP 6.1.2 failing.

Hi.

We have VDP 6.1.2 with 4T capacity (6T net space). We tried to expand capacity from 4T -> 6T (6T ->9T).

On the vdp-configure storage tab we choosed Expand Storage and got the following message:

expand storage

-vdp: There are incorrect number of disks associated with vdp appliance.

We have two 4Tb storage luns assigned to VDP and one 4Tb lun is created for the expansion.

Now it seems that we cannot expand disks couse we don't have enough space on existing luns.

And becouse this error we can't assign the third lun to vdp to cover that required space.

Is there a chicken egg proglem or am I missed something?

How do we assign more disk space (lun) to VDP so we can do the disk expansion?

Enviroment is ESXi 6 with latest updates

Regards

Pasi

We are having the exact same error with 6TB assigned at setup. Did you manage to solve that without reinstalling?

Hi,

same here.

Is there already a solution for that?

I think a fresh install will not solve this issue.

Thanks JO

ha also here. Painfully.

very bad once vdp needs to recreated from scratch.

As needing to delete annotation Values. And then add again all vms manually again to get new ID.

Hope vmware provide API or and input list.

Supporting lot of vms without automization is horrible in Case of refreshments.

Hi Max,

is that an official solution from the VMware Support?

Can you try to click the extend button again after you have extended your disk?

Will you get the error again?

I think a fresh install will not help if you will extend your disk once again.....

Thanks JO

‌i have lot of issues with vdp overally.

VDP checkpoint out of date

service troubles

java consuming lot ressources

often connectivity errors - need to restart Tomcat

Even with 6.x versions.

and today for any reason without any message vdp lost more then 100vms in the backup job.

To avoid expand problems - i choosed bigger Size on Deployment and did Thin provisioning.

Painfully. But yeah its free ha

best regards

Hi

I also have similar issue , the issue got resolved by changing configuration file

  1. Use Vi to open file under /usr/local/vdr/etc/vdr-configuration.xml
  2. Edit that file and changed <numberOfDisk>3</numberOfDisk> to <numberOfDisk>6</numberOfDisk> ( If you expanding from 4TB change 3 to 6, if you are expanding 6TB change same 9) 
  3. Try to expand the appliance again.

Can confirm srikanthrao147's suggestion works. I also had to modify the same entry in the vdr-configuration-deployed.xml

Can confirm srikanthrao147's solution works.

VMware support used it today on our system (VDP 6.1.2.19) and it solved the problem.
