scst: Invalid configuration encountered. Attribute 'dif_checks_failed' has an invalid value.

Hi Everyone,

Getting a previously unseen error when trying to initialize SCST (rc.scst start):

My /etc/scst.conf is built as per the master branch scripts -- basically scstadmin -write_config /etc/scst.conf.

I'm not able to track down any dif_checks_failed docs online..  

Applying SCST configuration...

Collecting current configuration: done.

-> Checking configuration file '/etc/scst.conf' for errors.

-> WARNING: No HANDLER section defined. Only physical media will be configured for targets.

-> WARNING: Driver 'iscsi' has no configured targets.

-> Done, 2 warnings found.

-> Applying configuration.

FATAL: Received the following error:

Invalid configuration encountered. Attribute 'dif_checks_failed' has an invalid value.

/etc/scst.conf:

I posted a patch to the scst-devel list earlier today to fix this... I
expect they'll commit it relatively soon, and once they do I'll update
ESOS. As a work-around you can delete that line from the saved config
file (dif_checks_failed).
