OS volumes

Image Streamer creates OS volumes as a result of the deployment process. An OS volume is associated with an HPE OneView server profile and can be assigned to a physical server as needed. Image Streamer preserves OS volumes whenever possible when server profiles are assigned to physical servers, unassigned from the server hardware, and moved between servers. An OS volume can be retained, deleted, or regenerated based on the actions performed on server profiles and logical enclosures.

An OS volume is used by the server to boot, and runs until the end of life of a server profile. Some server profile operations like assign, unassign, and reassign might require redeployment and creation of a new OS volume for the hardware. During redeployment, you are requested to either proceed or cancel the operations.

OS volumes status scenarios
Scenario	OS volume status
A server profile is assigned to or unassigned from physical server hardware	OS volume is retained
A server profile is assigned to a logical enclosure that is moved to a different enclosure group	OS volume is retained
A server profile is unassigned and the corresponding logical enclosure is subsequently deleted	OS volume is deleted
A server profile is assigned to a server hardware that cannot access the OS volume since it is in a different logical enclosure.	OS volume is deleted and regenerated from the OS Deployment Plan
`Server Hardware Type` of a server profile is modified	OS volume is deleted and regenerated from the OS Deployment Plan

Select the desired OS volume on the master pane of OS Volumes screen to see more details about it. Some important fields on the OS Volumes screen are:

State: Provides information about health of the OS volume.
Provisioned Capacity: Displays the current provisioned capacity of the selected OS volume.
Allocated Capacity: Displays the total allocated capacity for the selected OS volume.
iSCSI name: Displays the name of the iSCSI target. The iSCSI name is the identifier created when an OS volume is deployed.
IP address: Displays the IPv4 address of the virtual storage, where the OS volume is present.
Port number: Displays the port number on which the virtual storage hosting the OS volume listens.
