OL-28629-01

Cisco UCS Blade Server

Upgrade Scenario 1: UCSM and BIOS Earlier Than Version 2.2(2c), CPU Earlier Than Intel E5-4600 v2

This scenario assumes the following conditions:

• The Cisco UCS Manager software is at a version earlier than 2.2(2c).

• The server is at a BIOS/CIMC version earlier than 2.2(2c).

• The server is using CPUs earlier than Intel E5-4600 v2 Series.

In this case, use the following procedure to upgrade the server and CPUs.

Step 1 Upgrade the Cisco UCS Manager software to version 2.2(2c) or later. The required server CIMC and

BIOS are also included with the 2.2(2c) download bundle.

Use the procedures in the appropriate upgrade guide for Release 2.1 (depending on your current software

version): UCS Manager Install and Upgrade Guides.

Step 2 Use Cisco UCS Manager 2.2(2c) to upgrade and activate the server CIMC to version 2.2(2c) or later.

Use the GUI or CLI procedures in the UCS Manager Install and Upgrade Guides.

Step 3 Use Cisco UCS Manager 2.2(2c) to upgrade and activate the server BIOS to version 2.2(2c) or later.

Use the GUI or CLI procedures in the UCS Manager Install and Upgrade Guides.

Step 4 Disassociate the server in Cisco UCS Manager.

Step 5 Power off the server.

Step 6 Replace the CPUs with the Intel E5-4600 v2 Series CPUs.

Use the procedures in the Blade Server Installation and Service Note for your server.

Step 7 Reinsert the server to the chassis.

Step 8 Wait for Cisco UCS Manager to automatically discover the server.

Note At this point, the Health LED of the server shows a critical fault and Cisco UCS Manager reports

a generic error message: WILL_BOOT_FAULT: Sensor failure asserted. This is because a board

controller activation is required, as described in the next step.

Step 9 Clear the WILL_BOOT_FAULT by using the Cisco UCS Manager GUI to reset the server CIMC:

a. In the Navigation pane, click the Equipment tab.

b. On the Equipment tab, expand Equipment > Chassis > Chassis number > Servers, then choose

your server.

c. In the Work pane, click the General tab.

d. In the Actions area, click Recover Server.

e. In the Recover Server dialog, click Reset CIMC (Server Controller), then click OK.

Wait for CIMC to reboot and for Cisco UCS Manager to do a shallow discovery of the server. This

takes two to three minutes. At the end of this process the WILL_BOOT_FAULT is cleared.

Upgrade Scenario 2: UCSM and BIOS at Version 2.2(2c) or Later, CPU Earlier Than Intel E5-4600 v2

This scenario assumes the following conditions:

• The Cisco UCS Manager software is at version 2.2(2c) or later.

OL-28629-01

Cisco UCS Blade Server

• The server is already using BIOS/CIMC version 2.2(2c) or later.

• The server is using CPUs earlier than Intel E5-4600 v2 Series CPUs.

In this case, the server already has the software and firmware prerequisites. Use the following procedure

to upgrade the CPUs:

Step 1 Disassociate the server in Cisco UCS Manager.

Step 2 Power off the server.

Step 3 Replace the CPUs with the Intel E5-4600 v2 Series CPUs.

Use the procedures in the Blade Server Installation and Service Note for your server.

Step 4 Reinsert the server to the chassis.

Step 5 Wait for Cisco UCS Manager to automatically discover the server.

Upgrade Scenario 3: UCSM at Version 2.2(2c) or Later, CPU is Intel E5-4600 v2, BIOS on Spare Earlier

Than Version 2.2(2c)

This scenario is unique to a field-service situation in which a server that is already running Intel

E5-4600 v2 Series CPUs must be replaced, but the only replacement server available is running a BIOS

earlier than 2.2(2c).

This scenario assumes the following conditions:

• The Cisco UCS Manager software is at version 2.2(2c) or later.

• The replacement server is using Intel E5-4600 v2 Series CPUs (after the CPUs are transferred from

the old server).

• The replacement server is using BIOS/CIMC version earlier than 2.2(2c).

Use the following procedure to upgrade the replacement server BIOS to the required version:

Step 1 Disassociate the server in Cisco UCS Manager.2.2(2c)

Step 2 Power off the server.

Step 3 Transfer the CPUs from the old server to the new replacement server.

Use the procedures in the Blade Server Installation and Service Note for your server.

Step 4 Insert the server into the chassis that is running Cisco UCS Manager 2.2(2c) or later.

Note The server does not boot and discovery of the server hangs waiting for BIOS POST to complete

because the BIOS is at an earlier version that does not support E5-4600 v2 Series CPUs.

Step 5 Use the Cisco UCS Manager CLI to upgrade the BIOS. Use the following sequence of commands:

Note The show image command in the sequence below lists the firmware versions available for the

server. Always activate the latest firmware image version when you use the

update firmware command.

# scope server <chassis/blade>

chassis/server # scope bios

chassis/server/bios # show image

chassis/server/bios # update firmware <server_model>.<firmware version>

chassis/server/bios* # commit-buffer

Step 6 Wait for the update to complete. Check the status of the update and wait until the following command

returns Status: Ready. It takes a few minutes for the Status to return Ready.

chassis/server/bios # show update status

Status: Ready

Step 7 Activate the new BIOS:

chassis/server/bios # activate firmware <server_model>.<firmware version>

Warning: When committed this command will reset the end-point

chassis/server/bios* # commit-buffer

chassis/server/bios # exit

Step 8 Power-cycle the server to get discovery out of the hang state:

chassis/server # cycle cycle-immediate

chassis/server* # commit-buffer

Cisco UCS Blade Server

Cisco UCS Manager is now able to complete auto-discovery of the server.

Step 9 Use Cisco UCS Manager 2.2(2c) to upgrade and activate the server CIMC to version 2.2(2c) or later.

Use the GUI or CLI procedures in the UCS Manager Install and Upgrade Guides.

Step 10 Wait for the server to be discovered and by Cisco UCS Manager.

Step 11 Perform a board controller activation by using the Cisco UCS Manager CLI interface. Use the following

sequence of commands:

Note The server automatically reboots after the commit-buffer command is executed.

Note The show image command in the sequence below lists the board controller versions available for

the server. Always activate the latest board controller image version when you use the

activate firmware command.

# scope server <chassis/server>

# scope boardcontroller

# show image

# activate firmware <boardcontroller version>.0 force

# commit-buffer

See also Sample Board Controller Activation Command Sequence, page 8.

Step 12 Do not continue with the next step until the board controller activation completes. Verify whether the

activation is complete by using the show version command.

As shown in the example below, wait until the Activate-Status returns Ready. This process takes a few

minutes before Activate-status is successfully completed and returns Ready.

# show version

BoardController:

Running-Vers: 8.0

Package-Vers:

Activate-Status: Ready

Step 13 Clear the WILL_BOOT_FAULT by using the Cisco UCS Manager GUI to reset the server CIMC:

a. In the Navigation pane, click the Equipment tab.

b. On the Equipment tab, expand Equipment > Chassis > Chassis number > Servers, then choose

your server.

c. In the Work pane, click the General tab.

d. In the Actions area, click Recover Server.

e. In the Recover Server dialog, click Reset CIMC (Server Controller), then click OK.

Wait for CIMC to reboot and for Cisco UCS Manager to do a shallow discovery of the server. This

takes two to three minutes. At the end of this process the WILL_BOOT_FAULT is cleared.
