To enable or disable spinup and set the delay between spinups

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,

depending on the number of ports on the controller.

Viewing Information About a Phy

The 3ware 9750 RAID controller has 8 phy transceivers (phys) that receive

and transmit the serial data stream between the controller and drives and other

devices in the SAS domain.

Phys are associated with the SAS ports on the controller. Multiple phys can be

associated with one SAS port, which is then called a “wide port.” In the 9750,

there are two wide ports and each wide port has 4 phys.

You can check the phy properties on the Controller Phy Summary page.

To see information for a phy in 3DM 2

1 Select the controller for which you wish to view phy information from the

drop-down list on the menu bar.

2 If you have a direct-attached drive you can access the Controller Phy

Summary page from the

Information > Drive Information page by

clicking the phy ID for the drive. Otherwise, navigate to the

Management

> Controller Settings

page.

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, see /cx set autodetect=on|off disk=<p:-p>|all 3ware SATA+SAS RAID

Controller Card CLI Guide, Version 10.0.

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, search the LSI Knowledge Base for keyword 14889 (use the Advanced

Search) at https://selfservice.lsi.com/service/main.jsp
