Hey there,

I did some research already but wasn’t able to find what I was looking for, so I’m trying a quick shot here:

Does anyone know if it’s actually possible to throttle a vol move on cDOT?

vol move start does not really list an option for that and once the move is running, there’s also no vol move modify or anything like that.

*> vol move start ?

  (volume move start)

    -vserver <vserver name>                                           Vserver Name

   [-volume] <volume name>                                            Volume Name

   [-destination-aggregate] <aggregate name>                          Destination Aggregate

  [[-cutover-window] {30..300}]                                       Cutover time window in seconds (default: 45)

  [ -cutover-attempts {1..25} ]                                       Number of Cutover attempts (default: 3)

  [ -cutover-action {abort_on_failure|defer_on_failure|force|wait} ]  Action for Cutover (default: defer_on_failure)

  [ -perform-validation-only [true] ]                                 Performs validation checks only (default: false)

  [ -foreground {true|false} ]                                        Foreground Process

  [ -bypass-throttling {true|false} ]                                 *Bypass Replication Engine Throttling

  [ -skip-delta-calculation {true|false} ]                            *Skip the Delta Calculation

I’m currently migrating quite some big volumes from SAS to SATA across heads and the SATA aggregate is of course experiencing some lag now, so I’d love to throttle that a bit if possible.

Any idea?

Would a QoS policy on the souce volume help here or does NetApp internal stuff (like a vol move) override QoS quotas?

Best,
