How to add a qtree to an existing Snapvault Job (Protection Manager)

Hello,

 

we have a primary and a secondary site, on the primary site is a volume called Gruppen, inside are many qtrees. These qtrees are backuped via SnapVault to the secondary site to the backup volume.

We created a new qtree inside the primary volume Gruppen.

We then tried to add the newly created qtree to the existing Dataset in Protection Manager (primary physical ressources), however Protection Manager wants to create a new flexible Volume with only the relationship with the newly created qtree.

 

1) Is it possible to create a new qtree and add it to the job, without the provisioning of a new volume?

2) If it is possible, what's the way to achieve this?

 

Thank you!

    Hi Michael,

         By default you can only have 50 relationship going to a secondary volume. If this is a 51st qtree then it will not create the relationship in the existing  volume rather try to create a new one.

     

    If you want to make it into the same volume you will have to tune a option as follows. This will allow you to use the same secondary volume upto 100 relationships.

    dfm option set pmMaxSvRelsPerSecondaryVol=100.

      Hi Adai,

       

      this was a good guess, but unfortunately is this not the problem, there are about 15 Qtrees inside the volume.

      Could this be an issue with the volume size? Because Protection Manager wants to create a new volume of size 9TB!

       

       

      Primary:

      Filesystem                         total                 used                avail capacity                 Mounted on

      /vol/Gruppen/                     5068GB          3419GB          1649GB      67%            /vol/Gruppen/

      /vol/Gruppen/.snapshot     563GB           347GB               215GB      62%            /vol/Gruppen/.snapshot

       

       

      Secondary:

      Filesystem                         total            used           avail capacity            Mounted on

      /vol/Gruppen/                     5734GB     4262GB     1471GB      74%       /vol/Gruppen/

      /vol/Gruppen/.snapshot     1433GB      466GB      967GB      33%          /vol/Gruppen/.snapshot

        Hi Michael,

             These are the conditions under which PM creates a new secondary volume.

         

        When

        • Maxrelspersecondaryvolume
          • You exceed the default(50) # of relationship. This is not your case
        • PlatformDedupeLimit
          • Adding the new member may require the secondary be increased, but cant be done due to the max dedupe limit supported for the given platform
        • Volume Language.
          • The new members volume language is different from that of the exisitng secondary volume
        • Fan-In
          • If the new member exceeds the max-fan in ratio

         

        If the new qtree you are adding is from the same primary  volume  then you should experience case 2.
