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.
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.
- Enter advanced privilege mode: priv set advanced
- Initiate the expansion: aggr 64bit-upgrade start aggr_name
- Depending on the result of the preceding step, take the appropriate action:
|If the command...
||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.
- 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.
- Optional: Confirm that all volumes in the aggregate are 64-bit format: aggr 64bit-upgrade status aggr_name -all
- Return to administrative privilege mode: priv set admin
