● If no virtual disks are present, create at least one virtual disk.
● If physical disks are in non-RAID mode convert them to RAID mode using iDRAC interfaces such as iDRAC web interface,
RACADM, or WSMAN, or <CTRL+R>.
If you have assigned a physical disk as a global hot spare in Add to Pending Operation mode, the pending operation is created
but a job is not created. Then, if you try to unassign the same disk as global hot spare, the assign global hot spare pending
operation is cleared.
If you have unassigned a physical disk as a global hot spare in Add to Pending Operation mode, the pending operation is created
but a job is not created. Then, if you try to assign the same disk as a global hot spare, the unassign global hot spare pending
operation is cleared.
Assigning or unassigning global hot spare using web interface
To assign or unassign a global hot spare for a physical disk drive:
1. In the iDRAC web interface, go to Overview > Storage > Physical Disks > Setup.
The Setup Physical Disk page is displayed.
2. From the Controller drop-down menu, select the controller to view the associated physical disks.
3. To assign as a global hotspare, from the drop-down menus in the Action-Assign to All column, select Global Hotspare for
one or more physical disks.
4. To unassign a hot spare, from the drop-down menus in the Action-Assign to All column, select Unassign Hotspare for
one or more physical disks.
5. From the Apply Operation Mode drop-down menu, select when you want to apply the settings.
6. Click Apply.
Based on the selected operation mode, the settings are applied.

Converting a physical disk to RAID or non-RAID mode
Converting a physical disk to RAID mode enables the disk for all RAID operations. When a disk is in a non-RAID mode, the disk is
exposed to the operating system unlike unconfigured good disks and is used in a direct pass-through mode.
You can convert the physical disk drives to RAID or non-RAID mode by:
● Using iDRAC interfaces such as iDRAC web interface, RACADM, or WSMAN.
● Pressing Ctrl+R while restarting the server and selecting the required controller.
NOTE: Converting the mode is not supported on PERC hardware controllers running in HBA mode.
NOTE: Converting to non-RAID mode for PERC 8 controllers is supported only for PERC H310 and H330 controllers.
NOTE: If the physical drives connected to a PERC controller are in non-RAID mode, the size of the disk displayed in the
iDRAC interfaces, such as iDRAC GUI, RACADM, and WSMAN, may be slightly less than the actual size of the disk.
However, you can use the full capacity of the disk to deploy operating systems.
