NOTE: If the NVMe SSDs in the backplane slots support NVMe-MI commands and the I2C connection to backplane slots
are fine, the iDRAC discovers these NVMe SSDs and reports them in the interfaces irrespective of the PCI connections to
the respective backplane slots.
For more information about the displayed properties and to use the filter options, see the iDRAC Online Help.
Monitoring storage devices using RACADM
To view the storage device information, use the storage command.
For more information, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
Monitoring backplane using iDRAC settings utility
In the iDRAC Settings utility, go to System Summary. The iDRAC Settings.System Summary page is displayed. The
Backplane Inventory section displays the backplane information. For information about the fields, see the iDRAC Settings
Utility Online Help.
Viewing storage device topology
You can view the hierarchical physical containment view of the key storage components, that is, a list of controllers, enclosures
connected to the controller and a link to the physical disk contained in each enclosure. The physical disks attached directly to
the controller are also displayed.
To view the storage device topology, go to Storage > Overview. The Overview page displays the hierarchical representation
of the storage components in the system. The available options are:
Controllers
Physical Disks
Virtual Disks
Enclosures
Click the links to view the respective component details.
Managing physical disks
You can perform the following for physical disks:
View physical disk properties.
Assign or unassign physical disk as a global hot-spare.
Convert to RAID capable disk.
Convert to non-RAID disk.
Blink or unblink the LED.
Rebuild physical disk
Cancel rebuild physical disk
Cryptographic erase
Assigning or unassigning physical disk as global hot spare
A global hot spare is an unused backup disk that is part of the disk group. Hot spares remain in standby mode. When a physical
disk that is used in a virtual disk fails, the assigned hot spare is activated to replace the failed physical disk without interrupting
the system or requiring your intervention. When a hot spare is activated, it rebuilds the data for all redundant virtual disks that
were using the failed physical disk.
NOTE: From iDRAC v2.30.30.30 or later, you can add global hot spares when virtual disks are not created.
You can change the hot spare assignment by unassigning a disk and choosing another disk as needed. You can also assign more
than one physical disk as a global hot spare.
