3.9.4.3 Modify a Volume Clone
An Exascale volume clone is a thinly-provisioned read-write point-in-time copy of a volume snapshot.
To modify an existing Exascale
volume clone, use the ESCLI chvolume
command and specify:
-
The volume identifier for the volume clone. You can use the
lsvolume
command to find the volume identifier for each volume clone. -
The attributes that you want to change.
For a volume clone, you can modify the following attributes:
-
name=clone_name
: Modifies the name of the volume clone. -
iopsProvisioned=integer_value
: Modifies the I/O bandwidth provisioned for the volume clone. The I/O bandwidth is expressed as the number of I/Os per second (IOPS). -
iopsInherited={true|false}
: Specifies whether the volume clone inherits I/O bandwidth from the nearest ancestor in the volume hierarchy with provisioned I/O bandwidth (not inherited).If you change
iopsInherited
fromtrue
tofalse
, then the volume clone is governed by theiopsProvisioned
setting. IfiopsProvisioned
is not set to a value, then the default value isunlimited
.If you change
iopsInherited
fromfalse
totrue
, then the volume clone inherits I/O bandwidth from its nearest ancestor and any previousiopsProvisioned
setting is nullified.
For example, the following command changes the name of the specified volume clone:
@> chvolume 2:50e52177583f4be4bad68ac20b65001e --attributes name=myNewName
