Tab OK
The policy is enabled immediately.
You can set the number of drives that will spin up at the same time and the
delay time between drive group spinups. 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 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.
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,
see /cx set autodetect=on|off disk=<p:-p>|all 3ware Serial ATA RAID Controller CLI
Guide.
Note:
Some hard drives require that the power management jumper (PM2) be set
to enable staggered spinup, in order for the SATA OOB option to be used. For more
information, see the knowledgebase article 14889, at
KB/article.aspx?id=14889
