C93108TC-EX chassis ISSU

[Andy Guley]

I am trying to do an ISSU upgrade of my 93108 switch.  The switch is in NXOS mode.  I am getting getting the following error on the upgrade check:

Installer will perform impact only check. Please wait.
Pre-upgrade check failed. Return code 0x4093008A (Free space in bootflash is not enough for fast-reload or non-disruptive upgrade.
Minimum required free space is 2.5 times the target image size).

I also found this in the logs:

I have cleared some old firmware out of the bootflash.  There is one file that I am not sure what it is.

Any thoughts to what this is and if I can safely delete it?  My bootflash is not set to use it.  

Current Boot Variables:
sup-1
NXOS variable = bootflash:/nxos.9.3.2.bin
Boot POAP Disabled

Boot Variables on next reload:
sup-1
NXOS variable = bootflash:/nxos.9.3.2.bin

Hello @Andy Guley 

The "auto-s" file in your bootflash may be related to automatic software installation (ASI) feature of NX-OS, which allows you to configure your switch to automatically download and install software images from a designated server.
Before deleting the file, you may want to check if ASI is currently enabled on your switch and if the file is being used by it. T

To do this:

show install all status
If ASI is enabled, you may want to disable it before deleting the file to ensure that it won't cause any issues during or after the ISSU upgrade.

To disable ASI:

no feature auto-install
Once you have disabled ASI, you can try deleting the "auto-s" file and check if it frees up enough space for the upgrade.

If the upgrade check still fails, you may need to delete other files or consider upgrading the bootflash itself to a larger capacity.
