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.

Updating CMC Firmware Using Web Interface

NOTE

• Before applying the CMC update, ensure that the chassis is powered on. If the blades are powered on, it is not necessary to power

o the blades to perform the CMC update.

• Downgrading the CMC Firmware prior to 2.1 with external shared adapters is blocked.

To update the CMC rmware using the CMC web interface:

1 In the left pane, go to any of the following pages:

• Chassis Overview > Update

• Chassis Overview > Chassis Controller > Update

2 On the Firmware Update page, in the CMC Firmware section, select the required components under the Update Targets column for

the CMC or CMCs (if standby CMC is present) you want to update, and then click Apply CMC Update.

3 In the Firmware Image eld, click Browse (Internet Explorer or Firefox) or Choose File (Google Chrome) to browse through to the le

location. The default name of the CMC rmware image le is vrtx_cmc.bin.

4 Click Begin Firmware Update. The Firmware Update Progress section provides rmware update status information. A status

indicator displays on the page while the image le is uploaded. File transfer time varies based on the connection speed. When the

internal update process begins, the page automatically refreshes and the Firmware update timer is displayed.
