Hello,

Are you following a specific guide on converting back to standalone NX-OS from ACI mode? For example, https://supportforums.cisco.com/document/12268066/nexus-9000-standalone-nxos-aci-conversion-and-back

Are you receiving any error messages from the switch when trying to boot your NX-OS image? What NX-OS image version are you trying to boot to?

Thanks!

Yes I am attempting to convert back to standalone mode. I am trying to load image
  n9000-dk9.6.1.2.I3.4b.bin, and below is the error I receive.

Trying to read config file /boot/grub/menu.lst.recovery from (hd1,4)
 Filesystem type is ext2fs, partition type 0x83
No autoboot or failed autoboot. falling to loader

 

Can you confirm that image is in the bootflash of the switch and that it is not corrupted? The md5 hash of the file should be 76ee482c8f9c082c621380289264c6d7

I have tried 2 images with the same result. Could both images be corrupt?

Unlikely, but anything is possible.

I see that you have another thread on this issue and that is much further along than this thread. Your best bet for this issue would be to open a TAC case so the TAC engineer can see exactly what is going on before, during, and after this error message appears.

It appears Pasa was running into:

CSCus90279

We got on a webex and we got his switches successfully converted.

I have a similar problem when converting from ACI to standalone.  Here the issue is that when it goes back to standalone mode, software it not able to recognize the GEM card. This causes it to reboot.  Any suggestions ?

Two things:

1. Make sure the GEM Module is in the switch and seated well. You may want to try to reseat GEM Module.

2.  Make sure the your GEM Module Model is supported in your release  "n9000-dk9.7.0.3.I1.3.bin"

New Hardware Features in Cisco NX-OS Release 7.0(3)I2(1)

Cisco NX-OS Release 7.0(3)I2(1) supports the following new hardware features:

* Cisco Nexus 31128PQ switch
* Cisco Nexus 9372PX-E switch (enhanced version of the Cisco Nexus 9372PX switch)
* M6PQ-E uplink module (enhanced version of the M6PQ uplink module used for the Cisco Nexus 93120TX, 9396PX, and 9396TX switches)

thanks Tomas.

1) I have already done this re-seating multiple times. And the inventory seems fine:

2) You may be right on the nxos version though.. i am running n9000-dk9.7.0.3.I1.3.bin, but the hardware is supported from NX-OS Release 7.0(3)I2(1).

Will try with newer software.

Just to update the thread.

After upgrading to a later image  NXOS: version 7.0(3)I2(2a), the system boots up and GEM card is recognized.


Thanks Tomas
