Installing a new blade M620 in an existing M1000e

From the LCD display, I can read this for the new M620 server:

Warning CPU2 VTT PG: Version Change sensor for CPU2, firmware or software incompatibility (iDRRAC 9 with CMC) was asserted

You need at least CMC version 4.0 to support the M620.

You can find the Chassis Management update here

Version 4.50: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=D2KPX

Thanks.  4.50 supports the following:

PowerEdge M1000E
PowerEdge M820
PowerEdge M420
PowerEdge M620
PowerEdge M520

will it also support the M600 that we have in the same chassis ?

I updated the firmware to 4.50 and not I see the new M620 . I also update iKVM and iDRAC7.

I can also access the console, ready to install the OS. Perfect.

However, now I have the following message on M1000e Chassis Health ( chassis overview) :

      Chassis management controller (CMC) redundancy is lost.

I cannot figure out what it really means and how to get rid of it. Any suggestion ?

Well, if you have 2 cmc in the chassis, you will need to update both to firmware version 4.50

You also requested documentation: http://en.community.dell.com/techcenter/systems-management/w/wiki/1987.dell-chassis-management-controller.aspx

I am not aware that we have 2 CMC in the chassis. That would mean 2 controllers in the same chassis? How can I tell that I have two ( from the CMC web GUI for example) ? 

So far, I have been connecting to the CMC with the web GUI on  192.168.0.120 . How can I reach any other CMC ?

When you get to the section where you can upgrade the CMC firmware, it would list both the active and standby CMC. I usually update the standby first, and let it reboot, and then I update the active CMC. Updating the active CMC restarts it and forces a failover to the standby CMC, so if it's already on the new firmware, you only have to do this failover once.

Note that updating the CMC does not require shutting down the blades or so, but the fans in the chassis will run full speed for a minute or so while the CMC is rebooting (and unable to use its sensors to determine the temperature and lower the fan speed as it's not needing to run full speed).

Thank you for the reply. 

Here is what I see in the CMC update page:

and what I see on the Overview page:

So, I see only 1 CMC and I have a warning about lost redundancy. Is there any way I can "start" or see the other CMC ?

Just lookup the IP for the other CMC and connect to it. you can find the IP on the front LCD of the M1000e.

This info is all in the manuals link I provided in my previous post.

Thanks for the reply.

I cannot find the IP for the other CMC. On the LCD panel, I see only one ip:  192.168.0.120. I scan the whole subnet and could not find the other CMC.

I tried to update the firmware for the standby cmc from the RACADM:

$ racadm fwupdate -f 192.168.0.71 gilbert gilbert -d firmimg-4.5-A00.cmc -m cmc-standby
ERROR: 'cmc-standby' not listed in inventory

I tried to force a fail over:  http://en.community.dell.com/support-forums/servers/f/177/p/19386346/19897301.aspx

$ racadm cmcchangeover
ERROR: Unable to perform requested operation.

Can I simply shutdown, remove the active CMC and restart ? The standy (with old firmware) should kick in, isn't it ?

Thanks

The 2nd CMC wouldn't have a 2nd IP address; it's for failover only and boots up when the active CMC drops (due to failure or reboot after firmware update/intentional reboot) and then takes on the same identity. The 2nd CMC has it's own network ports to give redundancy there too (in case the network connection on the active CMC drops you can force a failover at the chassis).

You can safely pull the CMC out (an inch or so), wait a minute and then reinsert it again to let it boot up again. It will run the fans on the chassis at 100% speed while the CMC is out and till it's operational again, but the running blades shouldn't be affected.

Thanks for the suggestion.

I did pull out the active CMC (1). I waited for a good 5 minute with the fans running at 100%. The other CMC (2) never took over.

I put back the CMC (1) and after 2-3 minutes it booted and the fans slowed down. I still cannot see the other CMC (2) on the Web GUI and I still have a warning about lost redundancy.

The status light on the other CMC (2) is "Amber, glowing steadily" which means "Not Used" if I am not mistaken.

Why doesn't it boot and take over when the "active" one is out ?

How can I access it and update its firmware? Will I have to use a serial terminal straight to it ?

Thanks!
