dasd-eckd.a7b39e <bus ID of the DASD>: Path <cssid>.<chpid> (pathmask <logical path mask>) is disabled - IFCC threshold exceeded
Explanation
Due to numerous interface or channel control checks (IFCCs), a channel path
was removed from regular operations to retain good I/O performance.
User response
Ensure that the cabling between the storage server and the mainframe
system is securely in place.
Reset the device and channel paths by writing "all" or a logical path mask
to the path_reset sysfs attribute of the device.
If the problem persists, report it to your support organization.
