What Can Cause a Safe-Load Backup Capture to Fail
When you have Safe Load on, ECM captures the device’s configuration before
beginning the load process. If this initial capture fails, ECM displays the error
message “Capture for Safe Load failed” and stops the load.
To find out why the backup capture failed:
1. Convert the configuration to a template—if you do not already have it.
2. Try to capture the configuration with the template.
When ECM cannot capture a configuration with a template, it allows you
to view the attributes and their capture status in the Load Detail window.
3. View the Load Detail window.
The error messages in the Capture Status column indicate why the
configuration could not be captured. For example, you cannot capture a
write-only attribute since it can only be written to, not read.
For more information, see section Creating a Configuration with a Template,
on Page 4-27, and section Comparing Two Configurations, on Page 4-50.
What Can Cause a Rollback for Safe Load to Fail
A rollback can fail if ECM for any reason loses contact with the device it is
configuring.
For example: in a network, a connection could be broken or a technician at a
remote location could accidentally pull a card from the device being configured
while the configuration is in process.
Another example: If in the ECM configuration you change the device’s
community name, then set an attribute in Spectrum (say, how often Spectrum
might poll devices) and then in the ECM configuration return to the device to
set more device attributes, you will no longer have permission to contact that
device unless you have also modified the device’s community name in
SPECTRUM to agree with the new one you just created on the device. The
SPECTRUM community name for a device must agree with the community
name configured in the device.
A third example: if a configuration sets an attribute that changes a device’s
functionality so that other attributes disappear, when ECM tries find the no
longer existing attributes, it will not succeed and the rollback will fail.
