Setting Up Redundant Path Support On The Perc 6/E Adapter - Dell 6 series User Manual

1 Perform a controlled shutdown on the system in which the PERC 6/i
is installed.
2 Disconnect the system from the electrical outlet and remove the system
cover.
CAUTION:
Running a system without the system cover installed can cause
damage due to improper cooling.
3 Determine whether the dirty cache LED on the controller is illuminated.
• If the LED is illuminated, replace the system cover, reconnect the
system to power, turn on the system, and repeat step 1 and step 2.
• If the LED is not illuminated, continue with the next step.
CAUTION:
The PERC 6/i Integrated controller for Dell modular blade systems does
not have a dirty cache LED. A non-graceful system shutdown may result in the
controller containing dirty cache. If a non-graceful shutdown occurs, reboot the
system and ensure no cache-related warnings appear during POST. Then shut
down the system and remove the controller. If this is not done, cache data may be
discarded.
4 Locate the battery cable connection on the controller and disconnect the
battery.
Setting up Redundant Path Support on the
PERC 6/E Adapter
The PERC 6/E adapter can detect and use redundant paths to drives
contained in enclosures. With redundant paths to the same port of a device,
if one path fails, another path can be used to communicate between the
controller and the device. For more information about redundant paths,
see "Redundant Path With Static Load Balancing Support" on page 37.
To set up a configuration with redundant paths, both ports on a controller
must be cabled to the In ports of a single enclosure.
To add multiple enclosures, both Out ports of the first enclosure must be
cabled to the In ports of the next enclosure.
