Guidelines for Image File Locations
When upgrading your switch, we recommend that you keep on the active supervisor bootflash the Cisco
MDS SAN-OS system and kickstart image files for the release that your switch is running along with the
new release to which you want to upgrade. Because of the increasing size of the Cisco MDS SAN-OS
system image files, kickstart image files, and other binary files, it is difficult to have more than one
release of these files located on the active supervisor module bootflash on the Cisco MDS 9500 Series
switches. To accommodate the SSI boot image files and any third party binary files, Cisco MDS SAN-OS
Release 2.1(2b), and later, allows you to place these images on the SSM modflash. For details on the
available space on bootflash refer to the
