Unable to Discover C240 M3 on UCS environment

Hi All,

Does anyone know of an instant where C240 M3 servers are not discovered, in a UCS 2248/N2K (2232PP) environment. FI is running 2.1(a) and the C servers' firmware is 1.5. We are trying to connent through the single-wire management configuration,but we ar unable to disocever the servers.

Has anyone else esxperinced a similar issue ?

Regards,

Naleendra

Hi Naleendra,

For this particular set up you can only use the 2232 FEXes, I believe the 2248 are not supported


What adapter are you using for this setup (VIC P81E or 1225)? Single-Wire is only supported by the VIC 1225 the P81E

What is the Boot loader version running on the VIC?

Recommended — 2.1(0.457a)

Minimum required — 2.1(0.367e)

What slot is the VIC installed? for this server it should be PCIe slot 2

Can UCSM is able to see the server at all or just the FSM is falling to discover the server?(screenshots are useful)

Make sure the server is connected the same way as the screenshot below.

Dear Manuel,

Please see the answers below,

For this particular set up you can only use the 2232 FEXes, I believe the 2248 are not supported

We are using 2232PP

VIC 1225

What is the Boot loader version running on the VIC?

Minimum required — 2.1(0.367e)

It's 2.1 (cannot remember exact version, will check tomorrow)

What slot is the VIC installed? for this server it should be PCIe slot 2

PCIe 2

Can UCSM is able to see the server at all or just the FSM is falling to discover the server?(screenshots are useful)

UCSM cannot see a single server. (There are 6 C240 M3 servers.)

Make sure the server is connected the same way as the screenshot below.

It is single wire Management

We have two cables (10g) going from VIC to each N2K.

4 cables (10g) connect from each N2k to upstream 6248 FIs (first 4 ports)

We see two FExes and their backplane ports show as up but servers are not discovered.

Appreciate any other suggestion.

Thanks,

Indika.

Hi Indika,

Did you also remember to make sure the CIMC is set to factory default settings?  This is required for UCSM integration.

Hi Indika,

Mastin is right you need set the CIMC back to factory before trying to integrate these servers to UCSM.  You can set the cimc back to default by plugging in a monitor and a keyboard to the server. You will need to re-start the server and press f8 to get the cimc set up utility. Once you are in this utility should be able to set to default.

Hello All,

Yes, as Indika had told we had already folowed most of the recommended steps ( supported N2K/correct slot etc. ). However we hand't used he CIMC defaults and that did the trick.Upon setting the CIMC defaults, the servers were discoverd.
You've been a great help, and it is much appreciated.

Naleendra (along with Indika )

Hi Indika,

As Manuel and Mastin said:

The Factory default settings are Shared-LOM-Ext.

This option allows for UCSM integration using Single Wire Management with the VIC 1225.

Is this a C240 NEBS server by chance?  If so the C240 NEBS is not supported in 2.1(1) it requires 2.1(2).
