NOTE: Ensure that the latest firmware version is installed on your storage
controller. You can find the latest firmware and installation instructions on
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.
