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:

switch# copy running-config startup-config
Install and configure dual supervisor modules.
SSM intelligent services traffic on SSM ports is disrupted during upgrades. Fibre Channel switching
traffic is not disrupted under the following conditions:
–
Upgrade the SSI boot images on the SSMs on the switch to a release version supported by your
Cisco SAN-OS release. Refer to the
Storage Service Interface
All SSM applications are disabled. Use the show ssm provisioning CLI command to determine
