and to allow the controller to sequence the spin-up of drives. Compatible
drives are sent a spin up command based on the settings specified with the
policies
Number of drives per spin-up and Delay between spin-up
settings
. These policies can only be set using 3BM or the CLI.
•
Number of drives per spin-up. Number of drives that will spin up at
the same time when the controller is powered up, if staggered spin-up
is enabled. From 1 to x, depending on the number of ports on the
controller.
•
Delay between spin-up. The delay time (in seconds) between drive
groups that spin up at one time on this particular controller, if
staggered spin-up is enabled.
• Export JBOD (unconfigured) disks. This setting indicates whether
JBOD disks should be exported to the operating system. JBOD
configuration is strongly discouraged for newly added disks on a 9000
series controller, in favor of Single Disk, so by default, this setting is
disabled. If you have a JBOD configuration from a 7000/8000 controller
that you want to use on the 9000 series controller, you should enable this
setting. This policy can only be set in 3BM and CLI.
•
Staggered method. Indicates whether the type of staggered spin-up is
ATA-6 or SATA OOB (Out Of Band). By default, when Staggered Spin-
up is enabled, the ATA-6 scheme is used. If your drives support the SATA
OOB method, select that method in 3BM. There is no electronic method
for the controller to know if a drive supports this method, so it must be set
manually. For staggering to work properly, the drives must support the
selected method. This policy can only be set and only shows in 3BM.
Some additional policies can be set at the unit level. For more information,
see “Setting Unit Policies” on page 106.
Viewing Controller Policies
You can view the current state of controller policies in 3DM, in the Other
Controller Settings
section at the bottom of the Controller Settings page (See
Figure 39). Only the Auto Rebuild, Auto-Carving, and Carve Size policies
can be changed on this page. The other policies can be changed in 3BM or
through the CLI. For a summary of the initial default settings, see Table 6,
“Default Settings for Policies and Background Tasks,” on page 18.
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, see3ware Serial ATA RAID Controller CLI Guide.
