Merge Storage Pools
You can merge two storage pools to combine the contents of both pools. To merge multiple pools, merge two pools at a time until the desired storage pool is created.
NOTE: You cannot merge pools that have synchronous replication enabled.
IMPORTANT: Deduplication Domains cannot be merged, see Domains for details.
Merge storage pools.
pool --merge pool_name [target target]
Repeat this step for each of the pools you want to merge into the target.
Merge Pool1 to Targetpool1:
Nimble OS $ pool --merge Pool1 target Targetpool1
