traffic on any SSM installed on your MDS switch
Upgrading a Switch with Insufficient Space for Two Images on the Bootflash
To upgrade the SAN-OS image on a Cisco MDS 9000 Family switch requires enough space on the
internal CompactFlash (also referred to as bootflash) to accommodate both the old software image and
the new software image.
As of Cisco MDS SAN-OS Release 3.1(1), on MDS switches with a 256-MB CompactFlash, it is
possible in some scenarios that a user might be unable to fit two images on the bootflash. This lack of
space on the bootflash might cause the upgrade process to fail because new images are always copied
onto the bootflash during an upgrade.
The following MDS switches are affected by this issue:
•
•
•
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

all command.
