Dell Remote Access Controller/Modular Chassis Version 1.1 Module

General Information

If you have the Dell Remote Access Controller/Modular Chassis (DRAC/MC) version 1.1 module installed, ensure that you read that product’s readme.txt file. It contains updated information including how that module version affects system indicator behavior in certain conditions.

Important I/O Configuration Considerations

CAUTION: Data loss can result if you perform certain actions on a DRAC/MC 1.1 system in which the I/O bays have not been configured to fully support the operation of the version 1.1 firmware. Specifically, bay 2 should have an I/O module installed only if an identical module is present in bay 1, and bay 4 should have an I/O module installed only if an identical module is present in bay 3. Except in these cases (or in a case where you temporarily need to swap a failed I/O module in bay 1 or 3), bays 2 and 4 should be unoccupied.

Unless your system is configured accordingly, do not perform any of the following actions:

Upgrade DRAC/MC firmware

Issue a software reset command for a DRAC/MC, such as racadm racreset

Reseat a DRAC/MC module

Cause a DRAC/MC failover event, such as removing the network cable from the primary DRAC/MC

Performing any of these actions will power off and stop traffic on the bay 2 or bay 4 I/O module, resulting in data loss.

When initiated, the DRAC/MC version 1.1 firmware algorithm must find a module in bay 1 before bay 2 and a module in bay 3 before bay 4. Otherwise, the module in bay 2 or bay 4 will be powered off if you perform a firmware upgrade procedure on the DRAC/MC, cause a DRAC/MC failover, or reset the DRAC/MC.

See the Dell Remote Access Controller/Modular Chassis Version 1.1 User's Guide at support.dell.com for more information about configuring your DRAC/MC system.

Redundancy Support

If you are adding the DRAC/MC version 1.1 module to a system to enable redundancy, the firmware levels of both DRAC/MC modules must be version 1.1. If the DRAC/MC module currently in the system is version 1.0, you must upgrade the firmware of the current module to version 1.1 prior to installing the new DRAC/MC version 1.1 module.

NOTE: A DRAC/MC module’s firmware version is displayed on its web-based GUI or by typing the command getsysinfo or racadm getsysinfo.

NOTE: DRAC/MC version 1.1 firmware uses a different MAC address than the MAC address reported by DRAC/MC version 1.0 firmware. Therefore, a DHCP-assigned dynamic IP address may change after updating to the DRAC/MC version 1.1 firmware.
