Users Guide
The reconstruct task recreates the virtual disk after you have changed the RAID level or reconfigured the
virtual disk. The reconstruct rate, configurable between 0% and 100%, represents the percentage of the
system resources dedicated for running the reconstruct task. At 0%, the reconstruct has the lowest
priority for the controller, takes maximum time to complete, and has least impact to system performance.
A reconstruct rate of 0% does not mean that the reconstruct is stopped or paused.
At 100%, the reconstruct is the highest priority for the controller, the reconstruct time is minimized, and
has most impact to system performance.

To Change The Reconstruct Rate For A Controller
1. Type a numerical value in the Set New Reconstruct Rate (0-100) field. The value must be within the
0–100 range.
2. Click Apply Changes. To exit and cancel your changes, click Return to Previous Page.
To Locate Set Reconstruct Rate In Storage Management
1. In the Server Administrator window, under the system tree, expand Storage to display the controller
objects.
2. Select a controller object.
3. Click Information/Configuration on the controller Properties page.
4. Select Set Reconstruct Rate from the Available Tasks drop-down menu.
5. Select Execute.
You can also locate this task from the Change Controller Properties drop-down menu.

Setting The Redundant Path Configuration
Does my Controller Support This Feature? See Supported Features.
Redundant path is supported only on external PERC cards that use firmware version 6.1 and later. A
redundant path internal to the system is not supported. MD1xxx enclosures are supported.
For redundant paths, the enclosure must be in the Unified mode however specific port connections are
not required. A connection from either controller ports to either EMM In ports creates the redundant path
as long as two cables are used. But, Redundant Path continues to appear in the field even as the
redundant path is removed. The redundant path ceases to appear only when it is cleared in the storage
management.
In a daisy-chain scenario, more than one enclosure can be connected to a controller in a redundant path
mode. You can connect up to three MD1000 and MD1120 to a PERC 6/E controller in a daisy-chain
enclosure. You can connect up to four MD1200 and MD1220 to a PERC H800 and PERC H810 controller
in a daisy-chain enclosure. You can connect up to four MD1400 and MD1420 to a PERC H830 controller
and SAS 12 Gbps adapter in a daisy-chain enclosure. For an example of a daisy-chain configuration (for
PERC 6/E controller), see the following image:
