1. Feature Overview:
Feature Id:	[201542]
a. Name of Feature:	FCP - Enhanced Trace Facility
b. Feature Description
The zfcp error recovery trace will be reworked and the remaining traces in s390dbf are updated under
consideration of:  - addition of trace entries for important events, if they are missing  - removal
of trace entries, when no information is gained from the trace entry  - rework of the content of
trace entries in order to pass meaningful information  - assignment of appropriate loglevels to
trace entries, to provide similar level of detail information through all trace facilities in same
debug level.

Additional Comments:	This feature is for validation, it is expected to get included into RHEL5.3

2. Feature Details:
Sponsor:	zSeries

Arch Specificity: Purely Arch Specific Code
Affects Kernel Modules: Yes
Delivery Mechanism: Direct from community
Category:	zSeries
Request Type:	Driver - Feature from IBM
d. Upstream Acceptance:	Accepted
Sponsor Priority	1
f. Severity: High
IBM Confidential:	no
Code Contribution:	IBM code
g. Component Version Target:	2.6.25

3. Business Case
Enhancing the zfcp tracing facility will allow faster problem determination in case of customer
situations by providing complete and meaningful trace information in appropriate levels of detail to
make internal states of operation transparent.
