Enabling and Setting Up Staggered Spin-up

3 On the Policy Settings page, Tab to the Carving Factor field, press Enter
to display the text entry box, enter the size you want (between 1024 GB
and 2048 GB) and press
Enter again to accept it.
4
Tab to OK and press Enter to select it.
The policy is enabled immediately.
Enabling and Setting Up Staggered Spin-up
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.
To enable or disable spinup and set the delay between spinups
1 At the main 3BM screen,
Tab to Policy and press Enter.
2 On the Policy
Control screen, Tab through these fields, making the
choices you want to use:
• Staggered Spinup: Choose enabled or disabled.
• Number of Drives Per Spinup: Select the number of drives—from 1
to 4, 8, 12, or 16, depending on the number of ports on the controller.
•
Delay between spinup: Select the number of seconds—from 1 to 6.
•
Staggered Method: Select either ATA-6 or SATA OOB as the type of
staggered spinup you want to use. For staggering to work correctly,
the drives must support the selected method. Check the
documentation for the drive to see which method is supported.
3
Tab to the OK button and press Enter.
You will notice a short delay as 3BM makes the policy changes.
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
