Users Guide

• If there are no disk drives available in ready state, insert additional disk drives and make sure that the drives are in ready state.
• If physical disks are in non-RAID mode convert them to RAID mode using iDRAC interfaces such as iDRAC web interface, RACADM,
Redfish or WSMan, or <CTRL+R>.
NOTE: During POST, press F2 to enter System Setup or Device Setup. CTRL+R option is no longer supported for
PERC 10. CTRL+R only works with PERC 9 while boot mode is set to BIOS.
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.
If the last VD is deleted, the global hot spares also returns to ready state.
If a PD is already a global hot spares, user can still assign it again as a global hot spares.
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 Configuration > Storage Configuration.
The Storage Configuration page is displayed.
2. From the Controller drop-down menu, select the controller to view the associated physical disks.
3. Click Physical Disk Configuration.
All the physical disks associated to the controller are displayed.
4. To assign as a global hotspare, from the drop-down menus in the Action column, select Assign Global Hotspare for one or more
physical disks.
5. To unassign a hot spare, from the drop-down menus in the Action column, select Unassign Hotspare for one or more physical disks.
6. Click Apply Now.
Depending on your requirement, you can also choose to apply At Next Reboot or At Scheduled Time. Based on the selected
operation mode, the settings are applied.
Assigning or unassigning global hot spare using RACADM
Use the storage command and specify the type as global hot spare.
For more information, see the iDRAC RACADM CLI Guide available at www.dell.com/idracmanuals.
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.
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 H330 are always in non-RAID mode. In other RAID controllers, they are always in RAID
mode.
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 Advanced Filter.
An elaborated list is displayed that allows you to configure different parameters.
