 3. 

In the Open dialog box, select the configuration file, click the

Open button, and select “Apply.”

 4. 

When prompted, confirm the new configuration.

Note: When adding a saved configuration to a replacement

controller, administrators should ensure that the number and size of 

the physical disks connected to the controller are exactly the same 

as they were when the configuration was saved.

Changing virtual disk properties and configurations

Administrators can modify properties (such as the read, write, I/O, 

and access policies) for virtual disks configured on the PERC 5/i by 

selecting the virtual disk in the left panel, then clicking the Operations

tab and selecting “Set Virtual Disk Properties” (see Figure 2).

To change virtual disk configurations, administrators can use 

the Dell SAS RSM Reconstruction Wizard, which allows changes

to the RAID level and virtual disk without data loss. (This feature 

is only available for virtual disks configured on the PERC 5/i.) For 

example, administrators can change the RAID level of a preconfig-

ured RAID-0 virtual disk as follows:

 1.

 Select a virtual disk in the left panel of the application’s main 

window, then select Operations>Advanced Operations>

Reconstruction Wizard in the menu bar.

 2. 

Click the Next button.

 3. 

Select a different RAID level from the drop-down menu in the

lower right corner of the window, then click the Finish button.

Administrators can monitor the reconstruction progress by 

selecting Group Operations>Show Progress in the menu bar.

Dell SAS RSM uses the Patrol Read controller feature to identify 

disk errors. Patrol Read can be run on disks configured in virtual 

disk arrays or as hot spares, and is designed to correct disk errors 

and restore data integrity.

Dell SAS RSM enables administrators to set the Patrol Read 

mode to Auto, Manual, or Disable. Auto mode initiates Patrol Read 

based on the schedule enforced by the controller, Manual mode 

enables administrators to start or stop Patrol Read manually, and 

Disable mode prevents Patrol Read from executing.

Dell SAS RSM monitors the activity and performance of controllers 

and the storage devices connected to them:

Controllers: Controller status is displayed in the left panel 

of the application’s main window. If a controller fails, a

small red circle appears to the right of the controller icon. To 

display complete controller information, administrators can

select the controller in the left panel and click the Properties

tab in the right panel.

Disk drives: Disk drive status is displayed in the left panel of 

the application’s main window. To display a graphical view

of the disk drive, administrators can select the drive in the 

left panel and click the Graphical View tab in the right panel.

Processes: Dell SAS RSM allows administrators to monitor the 

progress of rebuilds, consistency checks, and other processes by

selecting Group Operations>Show Progress in the menu bar.

Dell SAS RSM enables administrators to easily upgrade PERC 5/i 

controller firmware without rebooting the system. Administrators 

can perform a firmware upgrade as follows:

 1.  

Download the latest firmware packages from support.dell.com.

 2. 

In the left panel of the application’s main window, select the 

appropriate PERC 5/i.

 3. 

In the right panel, click the Operations tab and select “Flash

Firmware,” then click the Go button.

 4. 

Browse for the .ROM update file and click the OK button.

 5. 

When prompted to confirm the upgrade, click the Yes button.

Dell SAS RAID Storage Manager, which comes preinstalled on Dell 

PowerEdge SC servers and Dell Precision workstations, enables admin-

istrators to configure, monitor, and manage storage configurations on 

SAS controllers. Dell SAS RSM tools can enhance flexibility when 

managing storage devices in enterprise environments.
