Configuring the Flexible Flash Controller Properties

After you upgrade to the latest verison of CIMC or downgrade to a prior version, and reset the configuration, the server will access HV partition only.

Before You Begin

 

Procedure


Step 1  

In the Navigation pane, click the Storage tab.

Step 2  

On the Storage tab, click Cisco FlexFlash.

Step 3  

In the Controller Info tab, click Configure Operational Profile.

Step 4  

In the Operational Profile dialog box, update the following fields:

Name

Description

Controller field

The system-defined name of the selected Cisco Flexible Flash controller.

This name cannot be changed.

Virtual Drives Enabled field

The virtual drives that can be made available to the server as a USB-style drive.

A check box against single HV partition is displayed.

Note   

In the prior versions, four check boxes against each virtual drive are displayed. If you have created single partition and downgraded to prior version of CIMC, other virtual drives are displayed even though only HV is valid.

RAID Primary Member field

The slot in which the primary RAID member resides.

RAID Secondary Role field

The value must be secondary-active.

I/O Read Error Threshold field

The number of read errors that are permitted while accessing the Cisco Flexible Flash card. If the number of read errors exceeds this threshold on a card, the card is marked unhealthy.

To specify a read error threshold, enter an integer between 1 and 255. To specify that the card should never be disabled regardless of the number of errors encountered, enter 0 (zero).

I/O Write Error Threshold field

The number of write errors that are permitted while accessing the Cisco Flexible Flash card. If the number of write errors exceeds this threshold on a card, the card is marked unhealthy.

To specify a write error threshold, enter an integer between 1 and 255. To specify that the card should never be disabled regardless of the number of errors encountered, enter 0 (zero).

Clear Errors check box

If checked, the read/write errors are cleared when you click Save Changes.

Step 5  

Click Save Changes.

Hi Walter,

Thank you for your prompt response. Does it mean that we can configure RAID between two SD cards using Cisco Flexible Flash Controller.
