SSM Issues
SSM Fails to Boot
If the SSM fails to boot, you may see the following system message:
Error Message IMAGE_DNLD-SLOT#-2-ADDON_IMG_DNLD_FAILED: Module image download
process failed. [chars].
Explanation
The add-on image download to the module failed. This module is not operational until
an add-on image has been successfully installed.
Recommended Action Verify the location and version of your module image. Enter install module
CLI command or use a similar Fabric Manager/Device Manager procedure to download a new
module image.
Symptom SSM fails to boot.
Upgrading the SSI Image
You can specify the SSI boot image for a Storage Services Module (SSM) to configure Fibre Channel
switching and Intelligent Storage Services.
Note A newly installed SSM initially operates in Fibre Channel switching mode by default.
Note If you downgrade to a Cisco MDS SAN-OS release that does not support the SSM, you must power down
the module. The boot variables for the SSM are lost.
Table 3-3 SSM Fails to Boot
Symptom Possible Cause Solution
SSM fails to boot. SSI boot variable is not set. Set the boot variable and install the SSI image. See the
“Recovering a Replacement SSM” section on page 3-8.
SSI image is not present. Download the SSI image and install. See the “Upgrading
the SSI Image” section on page 3-4.
SSI image is not compatible with Cisco
SAN-OS image.
If an incorrect or incompatible SSI image is downloaded to
an SSM it fails to boot three times and is then powered
down. Refer to the Cisco MDS SAN-OS Release
Compatibility Matrix for Storage Service Interface Images
