l Complete "Create Virtual Disk Advanced Wizard (Step 2 of 4)." In this step, you select the channels and the disks to be used by the virtual disk. The
selections you make determine whether or not the virtual disk is channel-redundant.
There are specific RAID level and configuration requirements for implementing channel redundancy. You must select the same number of physical disks
on each channel that you use. See "Number of Physical Disks per Virtual Disk" for information on the number of physical disks that can be used for
different RAID levels. See "Controller-supported RAID Levels" for information on controller-specific implementations of the RAID levels.
Depending on the controller type, use one of the following procedures when completing "Create Virtual Disk Advanced Wizard (Step 2 of 4):"

Physical disk Selection for Channel-redundant Virtual Disks on PERC 3/DC, 3/QC, 4/DC, 4e/DC, 4/Di, and 4e/Di Controllers
The following sections describe creating a channel-redundant virtual disk using RAID 10 or RAID 50 on a PERC 3/DC, 3/QC, 4/DC, 4e/DC, 4/Di, or 4e/Di,
controller.
RAID 10
a. Select one physical disk on each of two channels. (In other words, each of the two channels will have a single disk selected.)
b. Select an additional disk on each of the two channels. You have now selected the minimum number of disks for a RAID 10.
c. Repeat "step b" until you have the desired number of disks.
d. Click Continue.
RAID 50
a. Select one physical disk on each of three channels. (In other words, each of the three channels will have a single disk selected.)
b. Select an additional disk on each of the three channels. You have now selected the minimum number of disks for a RAID 50. Continue selecting a
disk on each channel until you have selected the desired number of disks.
c. Repeat "step b" until you have the desired number of disks.
d. Click Continue.

you use.
d. Click Continue.
Connector Health
This screen displays the status of the connector and the components attached to the connector.

Connector Status
Component status is indicated by the severity. A component with a Warning or Critical/Failure status requires immediate attention to avoid data loss if
possible. A component's status may indicate the combined status of the component and its lower-level objects. See "Determining the Health Status for
Storage Components" for more information.
It may be useful to review the Alert Log for events indicating why a component has a Warning or Critical status. For additional troubleshooting information,
see "Troubleshooting."

Severity

Component Status
Normal/OK. The component is working as expected.
Warning/Non-critical. A probe or other monitoring device has detected a reading for the component that is above or below the acceptable level.
