VPLEX – Expanding Volumes

March 15, 2016 By Dave

Expanding volumes on your storage array is something that needs to be done from time to time. Its a pretty simple task and it should stay a pretty simple task as well if you have VPLEX implemented.

1. Expand the backend storage volume
2. Log into VPLEX, go to “Virtual Volumes” and select the virtual volume you want to expand. You should see that the volume is expandable by the amount you expanded the volume on your array.
   1. If VPLEX doesnt see the amount you expanded the volume by, click on “Storage Arrays” and re-discover array. This will discover anything VPLEX hadnt picked up since its last refresh
3. Click Expand.
4. Go into vCenter and expand the volume.

Poof! Should be done.. But what if something goes wrong?
In my case, someone changed the password on the account that was used to authenticate to RecoverPoint. The volume isn’t protected by RecoverPoint, but it still needs to communicate.
When trying to expand the volume, I would receive the following message.

This is what I did to fix it. This is non-disruptive to RecoverPoint replication

1. Log into VPLEX via putty and open VPLEXCLI
2. run “ll /recoverpoint/rpa-clusters”You will notice that there are warnings about the username and password. You will also notice from the shot above that VPLEX was not able to gather any information from the RPA’s.
3. You need to remove the RP clusters
   1. Run “rp rpa-cluster remove –rpa-cluster X.X.X.X (X.X.X.X represents the RP cluster IP)
4. Re-add the RecoverPoint RPA Clusters.
   1. run “rp rpa-cluster add -o X.X.X.X -u admin -c cluster-1
      1. You can specify the user you want to use here. If you create a custom account on the RPA’s, ensure that it has admin access.
   2. You will be prompted to enter the user password twice.
5. Re-run “ll /recoverpoint/rpa-clusters” to ensure VPLEX can communicate with the RPA’

You should now be able to go back into the VPLEX GUI and expand your volume.
