RHEL3 U7: Add SMART capabilities to libata.
Last modified: 2007-11-30 17:07:03 EST
Have requested business justfication from Dell.
What the heck is this?
libata part of the device driver stack for SATA support.
SMART is Self-Monitoring Analysis and Reporting Technology. It's basically a
system for disks to alert the OS "hey, I'm about to fail."
So, this request is apparently for SMART support for SATA devices.
Deferring to U5; missed the cutoff.
Yes, SMART code exists for libata, and has for a while.
We're waiting on two things:
1) SCSI technical committee to finalize the specification that allows "ATA
passthru", assigning critical opcode numbers, thus enabling submission of random
ATA commands -- ATA SMART commands in this case.
2) Someone to take 30 seconds and create a patch that filters out a few ATA
commands (not SMART related) that are not properly handled yet by the driver.
Number 1 just happened days ago, so this feature just takes a tiny bit of time.
It's already seen some community testing, for many weeks now, in its present form.
Seems simple, reconfirming as desirable in RHEL3 U5. If not simple, please put
back into ASSIGN_TO_PM
The ATA command pass-through code will also require updates -- four revisions of
the spec have passed-by since the code was implemented...

This patch seems to work...will need to be cleaned-up, of course...
Doh! Disregard that patch! Too many bugzilla entries open at once...
Dell requesting for RHEL3U7.
Changing Summary to U7 becasue IT creating it requesting U7 implementation.
This enhancement request was evaluated by Red Hat Product Management for
inclusion in a Red Hat Enterprise Linux maintenance release.
Product Management has requested further review of this enhancement by Red Hat
Engineering, for potential inclusion in a Red Hat Enterprise Linux Update
release for currently deployed products.
This enhancement is not yet committed for inclusion in an Update release.
Fixing state field (from INVESTIGATE to ASSIGNED).
PeterM, please demote this off the MustFix list.
The SATA update that resolves this has just been committed to the
RHEL3 U7 patch pool this evening (in kernel version 2.4.21-38.EL).
Bugis public. Please put all future communication in bug 130712.
*** Bug 145596 has been marked as a duplicate of this bug. ***
This seems to work here (kernel version 2.4.21-38.EL) but smartctl needs "-d
ata" and this makes auto-scripting harder than before.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
