Deploying the PERC Card 41
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:
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
Figure 3-4.
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.

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