Users Guide

In the Storage > Enclosures > Properties page, the Physical Disks Overview section displays the following:
● Slot Empty — If a slot is empty.
● PCIe Capable — If there are no PCIe capable slots, this column is not displayed.
● Bus Protocol — If it is a universal backplane with PCIe SSD installed in one of the slots, this column displays PCIe.
● Hotspare — This column is not applicable for PCIe SSD.
NOTE: Hot swapping is supported for universal slots. If you want to remove a PCIe SSD drive and swap it with a SAS/
SATA drive, ensure that you first complete the PrepareToRemove task for the PCIe SSD drive. If you do not perform this
task, the host operating system may have issues such as a blue screen, kernel panic, and so on.
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 set command with the objects in the SGPIOMode group.
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/idracmanuals.
Set Enclosure Asset Tag
Set Enclosure Asset Tag allows you to configure Asset Tag of a storage enclosure.
User can change the Asset Tag property of the enclosure to identify enclosures. These fields are checked for invalid values and
an error is displayed if an invalid value is entered. These fields are part of the enclosure firmware; the data initially shown are the
values saved in the firmware.
NOTE: Asset Tag has a character limit of 10 that includes the null character.
NOTE: These operations are not supported on internal enclosures.
Set Enclosure Asset Name
Set Enclosure Asset Name allows the user to configure the Asset Name of a storage enclosure.
The user can change the Asset Name property of the enclosure to identify enclosures easily. These fields are checked for invalid
values and an error is displayed if an invalid value is entered. These fields are part of the enclosure firmware; the data initially
shown are the values saved in the firmware.
NOTE: Asset Name has a character limit of 32 that includes the null character.
NOTE: These operations are not supported on internal enclosures.
