PERC H200 and 6Gbps SAS HBA BIOS 55
CAUTION: Data on all disks will be lost. It is recommended that you back up all
data before performing these steps.
There are several limitations when creating a RAID 10 virtual disk:
• All disks must be either Dell-compliant SAS or SATA HDDs or SSDs.
• SAS and SATA physical disks cannot be used in the same virtual disk.
• HDDs and SSDs cannot be used in the same virtual disk.
• There must be a minimum of 4 physical disks and a maximum of
10 physical disks in a RAID 10 virtual disk. An even number of
physical disks need to be selected for a RAID 10 volume.

Press <C> and then select
Save changes
when the virtual disk has been
fully configured.
NOTE: There is an option to create a hot spare for a RAID 10 virtual disk.
After the virtual disk is created, entering the Manage Hot Spares screen
allows the option to assign a hot spare. Only drives that are compatible with
the new virtual disk configuration can be selected. There is a maximum of
2 hot spares supported globally. Hot spares only apply to a redundant volume
if it is of the same type and at least the same capacity of the volume.

Once the virtual disk has been created, a Background Initialization is
automatically scheduled on the virtual disk.
NOTE: RAID 10 provides protection against the failure of multiple physical
disks, as long as both drives within a mirrored pair do not fail. When a disk
fails, the physical disk can be replaced and the data re-mirrored to the
physical disk, maintaining data integrity.
NOTE: Only one background task can be performed on the PERC H200 card at any
time. If there is already a resynchronization or Background Initialization in progress
on another virtual disk when a new virtual disk is created, the Background
Initialization for the new virtual disk will be scheduled and given a status of BGI
Pending. The pending Background Initialization will automatically start when the
existing background process completes.
NOTE: A background initialization automatically starts after you configure a RAID 1
virtual disk. Once started, the background initialization process cannot be stopped.
