When transferring les to and from CMC, the le transfer icon spins during the transfer. If your icon is not animated, make sure that

your browser is congured to allow animations. For more information about allowing animations in the browser, see Allow Animations

Signed CMC Firmware Image

For VRTX CMC 2.0 and later, the rmware includes a signature. The CMC rmware veries the signature to ensure the authenticity

of the uploaded rmware. The rmware update process is successful only if the rmware image is authenticated by CMC to be a

valid image from the service provider and has not been altered. The rmware update process is stopped if CMC cannot verify the

signature of the uploaded rmware image. A warning event is then logged and an appropriate error message is displayed.

Signature verication can be performed on VRTX rmware versions 1.2 and later. For rmware downgrade to VRTX versions earlier

than 1.2, rst update the rmware to a VRTX CMC version that is later than or equal to 1.2, but earlier than 2.0. After this update,

rmware downgrade to earlier, unsigned VRTX versions can be performed.

Updating CMC and Mainboard Firmware

The shared capabilities of External Shared PERC 8 card are not available until both CMC and mainboard rmware are updated.

NOTE:

• To view the MD12x0 cabling diagram, refer to Upgrading PowerEdge VRTX to Support Shared Storage Expansion User's

Guide or Dell Shared PowerEdge RAID Controller (PERC) 8 Cards For Dell PowerEdge VRTX Systems User’s Guide

available at dell.com/support/manuals.

• The external shared storage adapter requires that you update the CMC v2.20 or later and mainboard v2.21 or later to

support External Shared PERC 8 card.

• You cannot downgrade the CMC rmware prior to 2.2 with external shared adapters.

To update the CMC and mainboard rmware:

1. Update CMC rmware.

2. Update mainboard rmware.

3. Power down the chassis and install shared storage adapters in PCIe slot 5 and slot 6.

4. Power on chassis.

5. After powering on the chassis, update external shared storage adapters.

NOTE: By default, the external shared External Shared PERC 8 card is in non-fault tolerant mode. It has to be changed to

Fault Tolerant mode after it is cabled appropriately. For more information, refer

Upgrading PowerEdge VRTX to Support

Shared Storage Expansion

In an event, if you want to rollback CMC or MPC/mainboard rmware or CMC and MPC rmware version, do the following tasks:

To Rollback the CMC and mainboard rmware:

1. Power o the chassis.

2. Remove all external storage adapters from the PCI slots.

3. Power on the chassis.

4. Roll back the CMC and/or mainboard rmware.

You cannot downgrade the CMC, if external shared storage adapter is detected.

If the processes are not followed in order, system behavior becomes random and parts of the system may become unstable. The

CMC logs IOV or RAID controller messages. Only shared storage VA mappings for PERC 1 and PERC 2 are visible in the older version

of CMC. All external shared storage VA mappings do not exist in the previous version of the CMC. If an External Shared PERC 8 card

is inserted after the rollback, the CMC treats it as a non-shared adapter. It may happen that the HOST PERC driver does not

support the External Shared PERC 8 card.
