Nexus 5500 Upgrade Issue: Pre-upgrade check failed. Return code 0x40930012

 

Introduction


The Cisco NX-OS software consists of the kickstart image and the system image. The system image includes the software for the Cisco Nexus device and the Cisco Nexus Fabric Extenders (FEXs) that are connected to the switch. NX-OS supports a technology called In-Service Software Upgrade (ISSU) that allows a Cisco Nexus 5000 Series switches and any connected FEXs to be upgraded without any traffic disruption (with a brief control plane disruption). You can choose to do a disruptive upgrade, if one of the ISSU conditions are not met.

 

Problem


Trying to upgrade a Nexus 5596 switch but it fails. This can be checked using following command

Nexus5596.A2-C06# sh install all impact kickstart bootflash:n5000-uk9-kickstart.6.0.2.N2.3.bin system bootflash:n5000-uk9.6.0.2.N2.3.bin

Checks before Installation

If you are doing an ISSU you should do certain sanity checks to ensure that the system is ready and to understand the impact of ISSU:

  • Use the show incompatibility command to verify that the target image is feature-wise compatible with the current image.
  • Use the show logging level command to ensure that the severity level for all processes is set to 5 or below.
  • Use the show install all impact command to identify the upgrade impact.
  • Use the show fex command to verify that all the FEXs are online.
  • Use the show vpc role command to verify the vPC switch role in a vPC topology.

 

Description


When a software upgrade is done on a Cisco Nexus switch, it copies the upgrade image in the flash and decompress it. The error "SRG extraction failed" means a failure while decompressing the upgrade image file. If the image file is not decompressed properly the upgrade process can not continue.
Use command "show system internal dir /var/tmp" to check for unwanted files also check for overall utilization of the flash.

Resolution


To resolve this issue free up the space in flash directory. Follow these steps:

1. In flash directory /var/tmp try to delete all .log files as these files are not required by the system. Do not delete any directory.
2. Check if there is an open telnet session locking a file in bootlash. The filename is "sup_params_info" and will be present in /var/tmp directory. Delete this file and see if you can continue with upgrade.
3. If still you are getting the error when trying to upgrade; reload the switch.
