Title:
[17.04 FEAT] DASD channel-path aware error recovery
Status in Ubuntu on IBM z Systems:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
Enhance the DASD driver to log path situations as an error and try to exclude
paths from further I/Os without risking an out-of-path situation to enable
users to reset this state when the cause has been resolved.
Example:
If a DASD is connected via multiple paths and one of these paths does not
work correctly (e.g. constant IFCCs, channel checks, or because HPF has stopped
working on this path),
Improve RAS especially during setup using DASDs. Resolve customer request,
avoid field reported problems
