Setting SGPIO Mode

The storage controller can connect to the backplane in I2C mode (default setting for Dell backplanes) or Serial General Purpose Input/Output (SGPIO) mode. This connection is required for blinking LEDs on the drives. Dell PERC controllers and backplane support both these modes. To support certain channel adapters, the backplane mode must be changed SGPIO mode.

The SGPIO mode is only supported for passive backplanes. It is not supported for expander-based backplanes or passive backplanes in downstream mode. Backplane firmware provides information on capability, current state, and requested state.

After LC wipe operation or iDRAC reset to default, the SGPIO mode is reset to disabled state. It compares the iDRAC setting with the backplane setting. If the backplane is set to SGPIO mode, iDRAC changes its setting to match the backplane setting.

Server power cycle is required for any change in setting to take effect.

You must have Server Control privilege to modify this setting.

NOTE: You cannot set the SGPIO mode using iDRAC Web interface.

Setting SGPIO Mode Using RACADM

To configure the SGPIO mode, use the SGPIOMode object with the set sub command. If it is set to disabled, it is I2C mode. If enabled, it is set to SGPIO mode. For more information, see the iDRAC RACADM Command Line Interface Reference Guide available at dell.com/support/manuals.

Choosing Operation Mode to Apply Settings

While creating and managing virtual disks, setting up physical disks, controllers, and enclosures or resetting controllers, before you apply the various settings, you must select the operation mode. That is, specify when you want to apply the settings:

Immediately

During the next system reboot

At a scheduled time

As a pending operation to be applied as a batch as part of a single job.

Choosing Operation Mode Using Web Interface
