Viewing Information About a Phy
The 3ware 9750 RAID controller family has multiple 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.”
You can check the phy properties on the Controller Phy Summary page.
To see information for a phy in 3DM2
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.
3Under
Other Controller Settings click the # link for Number of
Controller Phys
.
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.
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
