56 USC and USC - LCE
A foreign configuration is a set of physical disks containing a RAID
configuration that has been introduced to the system but is not yet managed
by the RAID controller to which it is attached. You may have a foreign
configuration if physical disks have been moved from a RAID controller on
another system to a RAID controller on the current system.
You have two options: Ignore Foreign Configuration and Clear Foreign
Configuration.
• If the foreign configuration contains data that you want to keep,
select
Ignore Foreign Configuration . If you select this option, the disk
space containing the foreign configuration is not available for use in a
new
virtual disk.
• To delete all data on the physical disks containing the foreign
configuration, select
Clear Foreign Configuration . This option frees the
disk space containing the foreign configuration and makes it available for
use in a new virtual disk.
Click Next after making your selection.
Select the Express or Advanced Wizard
• Create a virtual disk using either the Express Wizard or the
Advanced Wizard .
•The Express Wizard enables you to select the RAID level only.
The
Express Wizard then selects a virtual disk configuration for the user
which implements the selected RAID level and optionally enables you to
assign a hot spare. Select
Express Wizard to quickly create a virtual disk
using recommended settings. This wizard is not available on all controllers.
NOTE: If the available physical disks are using both Serial Attached
SCSI
(SAS) and Serial ATA (SATA) protocols, it is recommended that you use
the Advanced Wizard.
•The Advanced Wizard enables you to specify which protocol is used when
creating the disk pool for the virtual disks. A disk pool is a logical grouping
of disks attached to a RAID controller on which one or more virtual disks
can be created. In addition to the RAID level, the
Advanced Wizard allows
more flexibility with physical disk selection, span configuration, cache
policy, and other virtual disk attributes. Select
Advanced Wizard to specify
all virtual disk settings.
