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.
PERC 10 is not supported to convert drives to non-RAID. But it is supported in PERC 10.2 and higher versions.
You can convert the physical disk drives to RAID or non-RAID mode by:
Using iDRAC interfaces such as iDRAC web interface, RACADM, Redfish or WSMan.
Pressing <Ctrl+R> while restarting the server and selecting the required controller.
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, Redfish 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.
NOTE:
Hot plugged disks in PERC H330 are always in non-RAID mode. In other RAID controllers, they are always in RAID mode.
Hot plugged disks in PERC 11 are either ready or EPD-PT depending on the current auto configure behavior setting.
Converting physical disks to RAID capable or non-RAID mode using the
iDRAC web interface
To convert the physical disks to RAID mode or non-RAID mode, perform the following steps:
1. In the iDRAC web interface, click Storage > Overview > Physical Disks.
2. Click Filter options. Two options are displayed - Clear All Filters and Advanced Filter. Click Advanced Filter option.
An elaborated list is displayed that allows you to configure different parameters.
3. From the Group By drop-down menu, select an enclosure or virtual disks.
The parameters associated with the enclosure or the VD are displayed.
4. Click Apply, once you select all the desired parameters. For more information about the fields, see the iDRAC Online Help.
The settings are applied based on the option selected in the operation mode.
