To work around an image upgrade failure caused by a lack of space on the bootflash, follow these steps:
Prior to installing the new image, copy the old (existing) system image file to an external server. You
Step 1
may need to reinstall this file later.
Delete the old system image file from the bootflash by using either the Fabric Manager install utility or
Step 2
the CLI delete bootflash: command. The system image file does not contain the word "kickstart" in the
filename.
switch# delete bootflash:m9200-ek9-mz.3.0.3.bin
Note
Start the image upgrade or installation process using the Fabric Manager install utility or the CLI install
Step 3
all command.
If the new installation or upgrade fails while copying the image and you want to keep the old (existing)
Step 4
image, then copy the old image (that you saved to an external server in Step 1) to the bootflash using
either Fabric Manager or the copy command.
If the switch fails to boot, then follow the recovery procedure described in the "Troubleshooting Installs,
Step 5
Upgrades, and Reboots" section of the

On MDS 9500 Series switches, you also need to delete the image file from the standby
supervisor after deleting it from the active supervisor.
switch# delete
bootflash://sup-standby/m9500-sf1ek9-mz.3.0.3.bin
During the upgrade, configuration is not allowed and the fabric is expected to be stable.
The Fabric Shortest Path First (FSPF) timers must be configured to the default value of 20 seconds;
otherwise, the nondisruptive upgrade is blocked to ensure that the maximum down time for the
control plane can be 80 seconds.
If there are any CFS commits in the fabric, the nondisruptive upgrade will fail.
If there is a zone server merge in progress in the fabric, the nondisruptive upgrade will fail.
If a service terminates the nondisruptive upgrade, the show install all failure-reason command can
display the reason that the nondisruptive upgrade cannot proceed.
If there is not enough memory in the system to load the new images, the upgrade will be made
disruptive due to insufficient resources and the user will be notified in the compatibility table.
