This parameter allows you to control the number of drives used concurrently for writing objects on optical volumes within a storage group. Setting the DRIVE STARTUP THRESHOLD to the maximum of 9999 with no more than one volume mounted for a storage group increases the likelihood that OAM will write the objects sequentially. The default value for DRIVE STARTUP THRESHOLD is 17. |
