*** Bug 146186 has been marked as a duplicate of this bug. *** Created attachment 110321 [details]
This patch fixes st0: Error with sense data: Current st0: sense key Illegal Request" errors
This patch fixes "st0: Error with sense data: Current st0: sense key Illegal
Request" errors" seen on the ide tape drives on RHEL4.
Please include this patch for U1. whats the relevance of this patch to this bug ? I don't see how fixing those errors has anything to do with the lack of device nodes. if they are unrelated, can you create a seperate bug please ? as for the lack of device node - does anything show up in sysfs ? if not, that would be why udev didnt create anything. Darn. I wanted to piggyback that bugfix onto this issue. Oh well, I opened up a seperate bug 147496 to address the errors seen when accessing the drive. Comment on attachment 110321 [details]
This patch fixes st0: Error with sense data: Current st0: sense key Illegal Request" errors
Obsoleting this patch as this patch is not relevant to this (original)issue.
This patch has been appended to the correct Bugzilla (#147496)
Since the "sense data errors" issue has been opened seperately, I am trying to think aloud on what needs to be done to close this issue ? The problem in a summary is this: 1) Dell still needs to supports IDE Tape Drives with RHEL 4. 2) CONFIG_BLK_DEV_IDETAPE is not set in RHEL 4 kernel, hence no ide-tape module. 3) The workaround is to force load the deprecated "ide-scsi" driver when a need to use IDE tape drivers. 4) This is not working either since a simple tar operation using the "ide- scsi" driver is causing a kernel panic. See bugzilla 149979 for details. Therefore one of the two have to happen in order to close this issue: 1) Fix Bugzilla 149979. Patch is available. Then based on the "ide-scsi" workaround, we can close this issue. 2) Compile module support for "ide-tape" into RHEL 4 in a future Update. Can someone from RH comment on possible solutions and POR ? Bugzilla 149979 is on the mustfix list for U2. Assuming that happens, it appears to be a reasonable resolution for this bug. I'll mark this bug as depending on 149979. Since 149979 fixes the kernel panic this issue is a request to have the ide- tape driver compiled by default. Comment #8 > Bugzilla 149979 is on the mustfix list for U2. Assuming that happens, it appears to be a reasonable resolution for this bug. Sounds right. Given the "ide-scsi" woes we are experiencing, I have to question the reason RH choose to leave the "ide-tape" driver out of RHEL 4 kernel ? Was it inheritance from upstream or was it Q&A issues or someting else ? Can someone from RH respond to the question posted in comment #10 ? There have been plenty of bad experiences with the ide-tape driver (e.g. BZ 104453). ide-scsi was considered the better of the two alternatives, from a quality and maintainability perspective. Thanks for the response. We are investigating internally what those "other problems" are in ide-tape since that comment was made by someone from Dell in comment #9 from BZ 104453. As per the previous agreement, I have closed the It associated with this bug since we now have a functional workaround i.e. use the ide-scsi driver. The ide-scsi driver kernel panic issue (IT76670 / BZ149979) appears to be resolved in U2 Beta. RH, please close this bug. |
