Parameters
- Parameter:
cluster
- Possible Values: Any valid cluster.
- Description: The cluster on which to create the volume.
- Parameter:
eclabel
- Possible Values: Any label.
- Description: The label to use for the erasure-coded volume. See Using Storage Labels for more information on labels.
The label
should contain only the following characters:
A-Z a-z 0-9 _ - .
- Parameter:
ectopology
- Possible Values: Any topology that exists in your environment.
- Description: The new rack path for the erasure-coded volume if you are moving an
erasure-coded volume.
NOTE This parameter is applicable only for EC
volumes.
- Parameter:
label
- Possible Values: Any label.
- Description: The label to use for the storage pool. See Using Storage Labels for more information on labels.
The label should contain
only the following characters:
A-Z a-z 0-9 _ - .
TIP Use the special
label named anywhere to let a volume reside on any storage
pool. Not setting a label, causes a volume to reside only on a storage pool
without a label.
- Parameter:
name
- Possible Values: Any valid name
- Description: The name of the volume to move. For moving:
- An erasure coded volume, specify the name of the front-end volume.
- The metadata volume associated with a tier, specify the name of the
metadata volume.
The name should contain only the following characters:
A-Z a-z 0-9 _ - .
- Parameter:
nslabel
- Possible Values: Any value.
- Description: The label to use for the namespace container. See Using Storage Labels for more information on labels.
The label should contain only the following
characters:
A-Z a-z 0-9 _ - .
- Parameter:
topology
- Possible Values: Any
- Description:
The new rack
path for the:
- Regular or tiered standard volume, if you are moving a regular or tiered
standard volume.
- Regular or tiered mirror volume, if you are moving a regular or tiered
mirror volume.
- Metadata volume, if you are moving a metadata volume associated with a
tier.
This parameter is not required, if you are moving an erasure-coded
volume.
Advisory Note on Storage Labels
When the volume of a label is changed, replicas cannot be migrated within the file
server, from one SP with the old label to another SP with the desired label. If there no
other SPs, all old copies will not be fully migrated to the new desired label.
