NVRAM size mismatch between nodes detected

SEIMTEXTER

Hello,

 

I have a FAS2552 with each controller reporting this during boot.

 

Feb 15 15:10:57 [<arrayname>:nv.partner.size.mismatch:ALERT]: CF monitor: NVRAM size mismatch between nodes detected; node requires 661651456 bytes, partner exported 0 bytes.

 

Nodes are cabled correctly and it's just a 2-controller / no expansion switchless cluster running ONTAP 9.7.  Any ideas are welcome, but I need to get this fixed! 

 

Doesn't appear to be a bad NV DIMM -

 

2552::> system fru-check show
Node FRU Status

DIMM-1 pass
DIMM-NV1 pass
2552-02
DIMM-1 pass
DIMM-NV1 pass
BootMedia pass
PCIe Devices pass
6 entries were displayed.

What's going on here?

Hello,

 

Is the error mentioned only seen during boot?

Can you verify the health of the cluster:

Thanks

This could have happened during reboot while the interconnect was down.  

To verify the health of the interconnect, run  the command below.

::*>storage failover show -instance

 

If the interconnect link is fine, a takeover giveback should clear this issue.

yep, it's only during boot, and the array seems to be healthy otherwise.  Not sure if I should be concerned about it or just ignore it? 

 

> system ha interconnect status show

not sure where to run this.  it looks like ha can either expand out to hardware or halt, but is not valid by itself, at least at my runlevel (at the cluster(?) prompt)  Cdot is still pretty foreign to me, I mostly still work on 7-mode.

> cluster show

both nodes show true for health and true for eligibility, whatever that means, I assume it's good!

What is the serial #? It may be good to open a case if you have entitlements.

Re: NVRAM size mismatch between nodes detected

SEIMTEXTER

yeah we don't have entitlements or a support contract unfortunately.  Seems like it's working fine, it just spits that error out on boot ¯\_(ツ)_/¯

system ha interconnect status show is a privilege: advanced command.

::> set advanced

::*> system ha interconnect status show
