[uzbayev.marat1]

Hi Guys,

Want to upgrade nexus 3172T. 

Problem is that there are low free space to copy new .bin

Here what dir show:

Usage for bootflash://
797736960 bytes used
812666880 bytes free
1610403840 bytes total

and new nxos is 882479104 bytes. 

I cannot delete existing nxos file. types "Switch is booted with 'nxos.7.0.3.I4.2.bin'. Overwriting/deleting this image is not allowed". even after "no boot nxos"

Any ideas?

You need to compact the images:

You can cheat your way around it - delete the image via python (obviously substitute your file you are trying to remove)

switch# python
Python 2.7.5 (default, Oct  8 2013, 23:59:43)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.remove('/bootflash/nxos.7.0.3.I4.6.bin')
>>> exit()

In my case, I couldn't do the "install all nxos" because there was less than 650MB available after image copy, so I had to copy the target image to bootflash manually and then set "boot system nxos" variable. Then I was able to reboot the switch and it came up with the right code.

install all nxos nxos.7.0.3.I7.8.bin compact

After this CLI image become almost twice smaller.

Thi CLI doesn't do any installations, just squeeze the image
