Question

Adding new mount points to storage and if non global DDB's used for Aux copies will automatically use the new mount points

Setup: I have primary and secondary storage locations. Data gets copied from primary to secondary with Aux copies.  I have 3 Aux copies that are not tied to global deduplication DDB’s and are instead “using their own DDB” for the Aux copy to the secondary). I’m Looking to add more mount points to my media agents (to add more storage capacity) and I ran across this (copilot answer to “To determine whether a library is part of a Network Storage Pool in Commvault”):

  • Network Storage Pool is a logical construct that combines:
    • Disk Library.
    • One or more MediaAgents.
    • Global Deduplication Policy.
  • When configured, it enables shared access to mount paths across MediaAgents using DataServer-IP transport

My question is: If these Storage policies Aux copy are not tied to a global DDB, then its not part of a Storage pool (this appears to be the case when looking at Storage resources → storage pools as I can see only the Global DDB’s in the pools)? and if so if I add new mount paths to add storage space… will these Aux copies that have their own DDB’s “automatically use those new mount points”? In the storage policy copy properties → data path configuration → for these Aux copies, it has “automatically add new data path” selected… so I’m not sure if it will actually do this ‘completely automatically” or if I have to treat these in some special way/make manual changes after adding the new mount point.

Hi tigger2,

 

These storage policy copy DDBs define the storage target at the library level meaning it is mount path agnostic. Adding new mount paths to the library, whether it be disk or cloud, will be used in accordance to how data fills up each mount path (eg. Fill and spill, spill and fill, etc). But it will use all mount paths available where possible without any further configuration.
