Initialize volumes
A volume is automatically initialized when it is first created. However, the Recovery Guru might advise that you manually initialize a volume to recover from certain failure conditions. Use this option only under the guidance of technical support. You can select one or more volumes to initialize.
Before you begin
All I/O operations have been stopped.
Any devices or file systems on the volumes you want to initialize must be unmounted.
The volume is in Optimal status and no modification operations are in progress on the volume.
About this task
When you initialize a volume, the volume keeps its WWN, host assignments, allocated capacity, and reserved capacity settings. It also keeps the same Data Assurance (DA) settings and security settings.
The following types of volumes cannot be initialized:
Base volume of a snapshot volume
Primary volume in a mirror relationship
Secondary volume in a mirror relationship
Source volume in a volume copy
Target volume in a volume copy
Volume that already has an initialization in progress
This topic applies only to standard volumes created from pools or volume groups.
What happens next?
System Manager performs the following actions:
Erases all data from the volumes that were initialized.
Clears the block indices, which causes unwritten blocks to be read as if they are zero-filled (the volume appears to be completely empty).
Select
to view the progress of the initialize operation that is currently running for the selected volume. This operation can be lengthy and could affect system performance.
