Red Hat Bugzilla – Bug 218124
HTS: cdrom test failed
Last modified: 2008-07-16 17:57:10 EDT
Description of problem: After running "hts discover", I check the /var/hts/plan.xml and see that hts recognized DVD +/-RW as DVD+RW. Also, when running "hts certify", the output said "Your CD/DVD-ROM device /dev/hda supports (cd-rw,dvd,burnfree)". Version-Release number of selected component (if applicable): hts-5.0-9 How reproducible: easy Steps to Reproduce: 1.install RHEL5-x86_64 beta2 (everything installed) 2.Install hts*.rpm and dependences 3.run "hts plan" 4.run "hts discover" 5.run "hts certify" Actual results: The test is not correct for DVD +/-RW Expected results: Must test as the DVD type. Additional info:

could you please run "hts submit" on your test machine and attach the result rpm here ? we need more info.
Created attachment 142962 [details] Results rpm This test shows the cdrom test passed, but the test itself is incorrectly for this device. It supposed to test DVD writer (both format DVD +/- RW).
the Label for this cdrom device is "TEAC DVD+RW DV-W58E" http://www.teac.co.jp/dspd/product/optical/dv-w58e.html the system finds this cdrom as : - class: CDROM bus: IDE detached: 0 device: hda desc: "TEAC DVD+RW DV-W58E" - ----------------------- Dec 5 06:18:11 localhost kernel: hda: TEAC DVD+RW DV-W58E, ATAPI CD/DVD-ROM drive ----------------------- Typicall, a DVD+R/DVD+RW device now can also handle DVD-R/DVD-RW media too . The "+" and "-" do not have too much differences, so the "+/-" is not the big issue here. The problem is the system recognizes this device as a COMBO device , supports CD+/-RW and DVD-ROM , but no DVD+/-R or DVD+/-RW support: --------------------------------------- # cat proc/sys/dev/cdrom/info CD-ROM information, Id: cdrom.c 3.20 2003/12/17 drive name: hda drive speed: 40 drive # of slots: 1 Can close tray: 1 Can open tray: 1 Can lock tray: 1 Can change speed: 1 Can select disk: 0 Can read multisession: 1 Can read MCN: 1 Reports media changed: 1 Can play audio: 1 Can write CD-R: 1 Can write CD-RW: 1 Can read DVD: 1 Can write DVD-R: 0 Can write DVD-RAM: 0 Can read MRW: 1 Can write MRW: 1 Can write RAM: 1 --------------------------------------- So the CDROM test only checks (cd-rw,dvd,burnfree). The HTS itself works correctly. This is not an HTS's bug. I think following possibilities may lead to this problem: o The cdrom device is overly used and has been used for quite a long time, so it loses the capability of DVD+/-RW o need special device driver Dose this cdrom device work well(support DVD+/-RW) under other OS ?
I checked the detailed spec of this device , it supports DVD+R/RW in "Write/Read" mode and supports DVD-R/RW in only "Read" mode. So for us, it is a "DVD+R/RW" drive.
I think you're right. But the test is running as dvd read only. It doesn't do writing function (I used DVD+RW media). Do I need to close this bug and open another one or just change the summary?
After checking output.log, I saw that this test didn't even test DVD read only test. It failed to "cp files to ./device-copy". But it said on "hts print" that the test passed. ??????????????????
I've made an update of the CDROM test, will check both DVD-R/RW and DVD+R/RW and fixed this "DVD read only" problem. the update should be available in hts-5.0-15 .
Created attachment 145185 [details] results rpm cdrom test still failed on hts-5.0-15. See attachment.
reopening based on comment #9.

fixed in R17 .
Created attachment 146023 [details] output.log I retest. It seems working with CD-RW, DVD-ROM, but DVD+RW. Please check the output.log. It perform the test over 4.7GB capacity limit.
fixed in hts R18 .
When is hts R18 available to testers for verifying?
R18 is built and will be available very soon.

the fix is in hts-5.0 R23, not in R22. sorry for the inaccuracy.

Comment #27(In reply to comment #27) This is tested with HTS R23.
Warning and error messages: ------------------------------------- .... Start testing DVD+R ...

Please make sure you are using a NEW blank DVD+R disk to test DVD+R.

Please remove all *.xml files under /var/hts/ directory , then re-run "hts plan --server x.x.x.x" and "hts certify ..." etc.
Currently, the CDROM test will check for media types and status, it will quit with error if user insert wrong type of media or corrupted disk. We'll consider such enhancement like to let user re-insert disks if they insert wrong type or corrupted media for the next version of HTS.

(In reply to comment #29) Yes, It's really strange. I'm not so sure this message is for this bug# or bug#225438. Please check both bugs. Thanks,
HAL shows this TEAC DV-28PU External USB DVD-ROM Drive(TEAC_DVD_ROM_DV_28PU_DEF10BAB3A94) does support DVD+R, this is inconsistent with the spec. Anyway, if HAL sees it supports DVD+R, then we will check this feature. So please prepare a NEW blank DVD+R disc to re-test. Thanks
Created attachment 147783 [details] X-CD-Roast snapshot According to X-CD-Roast, this DV-28PU external dvd-rom is read-only. What is the different between HAL and X-CD-Roast, when they check for the functionality of this DVD? Please see the snapshot image.
Also, this device passed rhr2 test on rhel4. There is no reason hts is worse than rhr2, isn't it?

By default, X-CD-Roast CAN NOT handle DVD+R/DVD+RW media/feature, you can not see DVD+R/DVD+RW in the feature list, only CD-R/CD-RW/DVD-ROM/DVD-R/DVD-RAM are listed. HAL will list all features/media-types an optical device supports, following are the features which TEAC DV-28PU External USB DVD-ROM supports: -------------------------------------- storage.cdrom.hddvdrw = false (bool) storage.cdrom.hddvdr = false (bool) storage.cdrom.hddvd = false (bool) storage.cdrom.bdre = false (bool) storage.cdrom.bdr = false (bool) storage.cdrom.bd = false (bool) storage.cdrom.dvdplusrdl = true (bool) storage.cdrom.dvdplusrwdl = false (bool) storage.cdrom.dvdplusrw = false (bool) storage.cdrom.dvdplusr = true (bool) storage.cdrom.dvdram = false (bool) storage.cdrom.dvdrw = false (bool) storage.cdrom.dvdr = false (bool) storage.cdrom.dvd = true (bool) storage.cdrom.cdrw = false (bool) storage.cdrom.cdr = false (bool) -------------------------------------- we can see storage.cdrom.dvdplusr and storage.cdrom.dvdplusrdl are "true", this means the optical drive can write to DVD+R discs(DVD+R Dual-Layer discs). So, please prepare a NEW blank DVD+R disc to re-test. Thanks
(In reply to comment #36) > Also, this device passed rhr2 test on rhel4. There is no reason hts is worse > than rhr2, isn't it? > RHR2 does NOT check for DVD+R/DVD+RW features. Checking for DVD+R/DVD+RW are added in HTS.
According to TEAC DV-28PU External USB DVD-ROM Drive's spec: http://support.ap.dell.com/support/edocs/storage/P113634/en/spec.htm "write to DVD+R discs" is NOT supported. However, we find this device does support DVD+R. This is inconsistent. If the spec is accurate and up-to-date. If Dell intent to treat this device as a CD/DVD read-only(no DVD+R) device, then there is no need to test DVD+R, we will make an exception for this device.
Created attachment 149161 [details] everything about this cd-rw/dvd-rom drive Another drive failed the same. Please see attached file.
cd-rw/dvd-rom did passed on this device. HAL finds this optical device also supports DVD+RW, so the CDROM test continues to check DVD+RW . But this drive seems can not write DVD+RW disks. Interestingly, this issue only applies to TEAC's optical devices. This maybe an HAL's bug . Anyway, if the spec says the device only supports cd-rw/dvd-rom, and we do see cd-rw/dvd-rom passed in the CDROM test's output log, then we can certify this device regardless the DVD+RW's failure. What we are checking in the CDROM test are those features listed in the spec. Features which outside the spec are not required.
