connection between the controller and enclosures. After you remove the cable and power up the system,

ensure that there are no warning messages during boot, and that all virtual disks are online and optimal. If

you are using Dell OpenManage, see the Dell OpenManage documentation at dell.com/support/

manuals for additional instructions.

CAUTION: If you remove any cables other than the ones added to enable redundant path

support, the enclosure and disks can get disconnected, and virtual disk may fail.

Perform the following steps to configure the hardware to utilize redundant paths on the PERC H810 card:

1. Set up an enclosure on the PERC H810 card.

2. Connect two SAS cables from the Out ports on your PERC H810 card to the In ports of the external

enclosure. For more information, see the following figure.

NOTE: For information on Unified Mode, see the enclosure documentation that was shipped

with the enclosure.

3. To add multiple enclosures, cable both Out ports of the first enclosure to both In ports of the next

enclosure.

4. After you set up the hardware, the controller detects the redundant paths and automatically utilizes

them to balance the I/O load.
