Nexus 3548 OS upgrade issue

[Adnan Khan]

I have upgraded my OS from 6.0(2)A8(4a) Kickstart and System both to 6.0(2)A8(9) then I copied

7.0(3)I7(4) OS and run install all nxos command to upgrade but the error shows up as incompatibility.

Could anyone tell what will be the upgrade path to

6.0(2)A8(9) to 7.0(3)I7(4) 

[Vinutha Rao]

Hi,

 The upgrade path you mentioned is supported. 

Can you please provide the output of the install all cmd when it gave an error? 

In my lab, I tried the path - A8.4a -> A8.9 -> 7.0(3)I7(4) and upgrade does not give an error.

This is the output of error

Hi,

 This error is expected because the image needs to be of type compact. Please copy the image I7.4.bin again to the switch using the keyword 'compact' and try the upgrade again. 

Eg: 

MTC-CR# copy scp://<user>@<scp-server>/path-to-image/nxos.7.0.3.I7.4.bin bootflash: compact vrf management

Thanks,

Vinutha

Thanks Vinutha,

What will be the SCP-server address. I never used upgrade link like this. Can you put actual syntax with any dummy username. That will be really helpful please.

[Vinutha Rao]

Hi Adnan,

   Can you please let me know how you copied the image to the switch the first time? 

You can use tftp too, instead of scp, or any other option for remote copy, but make sure you copy from the switch itself and use compact keyword, as mentioned in the below eg. 

Dummy example: copy scp://user@1.1.1.1/path/image.bin bootflash: compact vrf management 

[Adnan Khan]

I copied it through USB1:

copy usb1:image.bin bootflash:

This SCP method will download image from Cisco website?

[Vinutha Rao]

Compact option cannot be used for local copies, so from usb its not possible.

You will have to download the image to a tftp/scp supported server and then copy the same from the switch console using the compact option.

Please refer the below guide:

[Adnan Khan]

Thanks, I will check and update here.

[Adnan Khan]

Copying using SCP any tftpserver can be used or different software is required? Also image should be downloaded on a SCP / TFTP Server right. It will not directly download from website and upgrade.

[Vinutha Rao]

Yes, image needs to be downloaded to a tftp/scp server and then should be copied from the switch. You can use copy tftp:// option if the server is a tftp server. Option 'compact' is supported for tftp as well.
