Enabling and Setting Up Staggered Spin-up
You can set the number of SAS and SATA drives that will spin up at the same time and the delay time between drive group spinups. This does not apply to SAS or SATA drives that are attached to an expander.
Three policy settings let you set the number of drives that will spin up at the same time and set the delay between drive groups that spin up at one time.
Not all SATA drives support staggered spinup. If you enable staggered spinup and have drives that do not support it, the setting will be ignored. You can change these settings in 3BM or using the CLI.

| Note: It is possible to enable or disable automatic detection of drives on the controller’s ports for staggered spinup during hot swapping of drives. This feature is only available in the CLI using the autodetect=on|off command. For more information, refer to /cx set autodetect=on|off disk=<p:-p>|all in the 3ware SATA+SAS RAID Controller Card CLI Guide, Version 10.2.
