Strange error message

We have 2 UCS domains running at 2.1.2a, which have been powered down, and moved to a new datacenter.

Now I see on both domain, on each FI, the error message: management interface is down (see file)

However, I can connect to UCS and use UCSM; something must be wrong here. The error cannot be removed,

by acking it.

Any advice is appreciated

Re: Strange error message

Walter,

Deducing you just moved these domains between data centers - any chance you don't yet have a Default Gateway that's reachable from your FIs?  The default Management Interface Monitoring policy tries to ping the default gateway - if its unable to do so, that fault will remain.

From your show tech, its indeed enabled:

`show mgmt-if-mon-policy`

Admin Status: Enabled

Polling Interval: 90

Max Failure Reports: 3

Monitoring mechanism: Ping Gateway

MII Status Settings:

-------------------

Mii Status Retry Interval: 5

Mii Status Retry Count: 3

Solution - Disable this policy or configure the Gateway

Regards,

Robert

Walter,

What does the cluster status show?  (show clust ext).

Just because UCSM is reachable doesn't mean there may not be a problem with one of the FIs.

Strange error message

Walter how long as the error been present?  It may just be a matter of a soaking-period (24hrs) for the error to self-clear.  This could have been a result of the FI's Mgmt interfaces being disconnected while still powered up before the move, or disconnected during power up after the move.

If its been longer than 24hrs, we'll need to look at a UCSM show tech to advise further.

Regards,

Robert

Re: Strange error message

The move of the UCS domains happened 1 week ago !

 

I add show tech, just in case someone likes to clarify

Re: Strange error message

Is the show tech you attached from the same as the system from the screenshot above?

The Fault ID from the screenshot doesn't appear in the logs and the faults in your screenshot have been acknowledged, whereas in the TechSupport bundle they have not.  The timestamps are also different.

Please confirm.

Re: Strange error message

Robert, you are correct ! this are 2 UCS domains, both show exactly the same error. Therefore I also uploaded the other show tech (see above)

Thanks Walter.

Re: Strange error message

Hi Rob

Indeed, this was the problem; one cannot ping the default gateway ! I changed the policy to MII Status; now the error is gone !

Thanks for your outstanding support (as usual)

Enjoy the weekend

Kind Regards

Walter.
