In a CVM environment, disconnecting and reconnecting hard disks may display an error

This issue may occur if you have configured volume resources in a cluster-shared disk group, and brought them online on the Slave node. Now if you disconnect the disk, the volume resources fail over to the Master node. If you reconnect the disk to the Slave node, and fail back the resources to the Slave node, a dialog box may appear asking you to format the volume, even when the volume is accessible. This dialog box can be safely ignored. (3274685)
