A thin-provisioned volume is offline because there is insufficient allocated real capacity available on the volume for the used space to increase further. If the thin-provisioned volume is auto-expand enabled, then the storage pool it is in also has no free space.
The service action differs depending on whether the thin-provisioned volume copy is auto-expand enabled or not. Whether the disk is auto-expand enabled or not is indicated in the error event data.
If the volume copy is auto-expand enabled, perform one or more of the following actions. When you complete all of the actions that you intend to perform, mark the error as "fixed"; the volume copy then returns online.
If the volume copy is not auto-expand enabled, perform one or more of the following actions. In this case, the error is automatically marked as "fixed", and the volume copy returns online when space is available.
