Expanding an aggregate to 64-bit without adding storage

You can expand a 32-bit aggregate to the 64-bit format without adding storage to it. This enables you to use capabilities that are supported only on 64-bit aggregates, and helps you remove 32-bit data from your storage system.

Before you begin

About this task

For volumes in a SnapMirror relationship, the destination volume inherits the format of the source volume while the mirror is intact. If the aggregate you are expanding contains a destination volume whose source is a 32-bit volume and you break the mirror before expanding the aggregate, the destination volume will be expanded to the 64-bit format. However, if you reestablish the mirror and the source volume is still 32-bit, the destination volume returns to the 32-bit format. For this reason, you must expand the aggregate containing the source volume before reestablishing the SnapMirror relationship if you want to expand all 32-bit volumes in the aggregate to the 64-bit format.


  1. Enter advanced privilege mode: priv set advanced
  2. Initiate the expansion: aggr 64bit-upgrade start aggr_name
  3. Depending on the result of the preceding step, take the appropriate action:
    If the command... Then...
    Initiates successfully Proceed to the next step.
    Indicates that one or more volumes could not be expanded because they did not have enough space Retry the command, adding the grow-all option.
    Indicates that the expansion could not be completed for some other reason Take the appropriate action, based on the issue outlined in the error message.
  4. Display the status of the expansion: aggr 64bit-upgrade status aggr_name
    The current status of the expansion is displayed. When the message that there is no upgrade in progress is displayed, the expansion is complete.
  5. Optional: Confirm that all volumes in the aggregate are 64-bit format: aggr 64bit-upgrade status aggr_name -all
  6. Return to administrative privilege mode: priv set admin
