Scenario

A shared EVS can be mounted to a cloud server as a data disk if the following conditions are met:

Property	Property Value
Shared disk or not	Shared (shared EVS)
Disk property	Data Disk
Disk status	"Unattached" or "Attached"

Note:

An EVS that has been initialised and contains data does not need to be initialised again after it is mounted. Initialisation will result in data loss. Therefore, exercise caution with this action.

Restriction and Limitations

A shared EVS can only be used as a data disk, not a system disk.
A shared EVS can be mounted to a maximum of 16 cloud servers at the same time. The cloud servers must reside in the same availability zone in the same region as the shared EVS.
If the shared disk is in the Attached state, ensure that the attach point of the shared disk is not full before attaching it to another cloud server.
