Reverting to Single Path Support from Redundant Path Support for PERC H810

If you need to revert to single path support from redundant path support, shut down the system and remove the exact same cables that were added to support redundant path support, leaving only one 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 support.dell.com/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:

1Set up an enclosure on the PERC H810 card.

2Connect two SAS cables from the Out ports on your PERC H810 card to the In ports of the external enclosure. For more information, see Figure 3-4.

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

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

4After you set up the hardware, the controller detects the redundant paths and automatically utilizes them to balance the I/O load.
