the Dell Support website at support.dell.com.

Reverting From Redundant Path Support to Single

Path Support on the PERC H800 Adapter

If you need to revert from redundant path support to single 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.
