Print detailed information about a specified NSS pool move. It lists the devices you are moving from and the devices you are moving to, such as
If a pool is cluster-enabled, the pool move is enabled and active only on the node where the pool cluster resource is currently online. On other nodes in the cluster, the pool move is not enabled.
nlvm [nlvm_options] list move <<move_name>|<pool_name>>
The move occurs as a low-level block mirror between the original location and the new location. The entire pool area is mirrored. The response reports the number of mirror regions to be moved for the pool relative to the maximum original pool size, which is unrelated to the NSS blocks in use. The region count for the old pool location does not change during the move. The complete parameter indicates the number of regions that have been moved so far and the percentage that it represents of the total number of regions to be moved.
The size of a mirror region is determined internally based on the total size of the mirror. One sector is used to track the number of mirror regions that are currently synchronized. A bit represents a mirror region, and there are 4096 bits total (512 * 8) to track. A shift technique is used so that the mirror region size is always a power of 2 (128, 256, 512, and so on) and the total number of regions to move is less than or equal to 4096. Except for very small mirrors, the number of mirror regions is usually between 2048 and 4096. The minimum mirror region size used is 64 sectors (32 KB). There is no maximum. For an 8 TB pool the mirror region size is 2 GB. When a complete region is mirrored, the bit is set. If a region is partially mirrored during a system failure or cluster resource migration, the entire region is remirrored when mirroring resumes.
The response lists the set of devices that are being used for the original location (from) and the new location (to).
Mandatory. Specify the name of the move, such as POOLNAME_move. You can alternatively specify the pool name.

The command returns the following information about the specified pool move:
