Patch Name: PHKL_27224 Patch Description: s700_800 11.00 IDE/ATAPI cumulative patch Creation Date: 02/07/29 Post Date: 02/07/31 Hardware Platforms - OS Releases: s700: 11.00 s800: 11.00 Products: N/A Filesets: OS-Core.CORE2-KRN,fr=B.11.00,fa=HP-UX_B.11.00_64,v=HP OS-Core.KERN2-RUN,fr=B.11.00,fa=HP-UX_B.11.00_64,v=HP Automatic Reboot?: Yes Status: General Release Critical: Yes PHKL_27224: ABORT OTHER CORRUPTION HANG High Priority Machine Check (HPMC) HP-UX installation abort Data corruption while reading from Teac DVD drive PHKL_26409: OTHER ABORT High Priority Machine Check (HPMC) HP-UX installation abort Category Tags: defect_repair hardware_enablement general_release critical halts_system corruption Path Name: /hp-ux_patches/s700_800/11.X/PHKL_27224 Symptoms: PHKL_27224: ( SR:8606259281 CR:JAGae23599 ) A High Priority Machine Check (HPMC) can occur when attempting to boot from a half-height DVD drive on current workstation models (B, C and J class systems). The HPMC is dependent upon timing conditions present during boot and may not occur with all kernels. Changing the configuration of the kernel may eliminate the HPMC. ( SR:8606269368 CR:JAGae33603 ) This defect has two symptoms and only occurs on multi-processor systems: 1. Data read from the slimline Teac DVD drive (A8069A) may appear corrupted. 2. A user process, such as the mount(1M) command, may hang for approximately fifteen minutes if issued while the IDE CD/DVD drive is becoming ready. At the end of this period the command will fail. If the command is issued again it will succeed. PHKL_26409: ( SR:8606237066 CR:JAGae06113 ) An HPMC can occur when attempting to boot from a half-height DVD drive on current workstation models (B, C and J class systems). ( SR:8606251613 CR:JAGae17678 ) When installing HP-UX from a CD-ROM media using the half- height DVD drive on current workstation models (B, C and J class systems), an error message similar to the following appears: "ERROR: Cannot open source device: /dev/dsk/c0t0d0: Device busy (errno = 16). NOTE: Default (boot) source does not appear to be a valid (or complete) install source, switching source to Network." PHKL_24282: (SR: 8606198839 CR: JAGad68028) Current IDE capable workstations do not support CD-RW drives. PHKL_22644: Diskinfo (1M) coredumps or reports random data for empty CD-ROM drive PHKL_22031: After upgrading a B1000, B2000, C3X00, J5X00, J6000, or J7000 workstation from HP-UX 10.20 to HP-UX 11.00 using a software depot containing the patch PHKL_20822, a kernel is created without the "side" driver resulting in the CD-ROM drive not being accessible. PHKL_20822: ( SR: 8606110752 CR: JAGab83500 ) Under heavy CD-ROM load, various error messages would be written to syslog, such as "DMA timeout", "Ktimeout on a DMA read", "Failed to set up DMA bus master reg", etc. Although there was no data corruption, the messages would be both annoying and possibly distressing. PHKL_20154: ( SR: 8606107507 DTS: JAGab77743 ) 11.00 ACE New Workstation/Server Functionality Defect Description: PHKL_27224: ( SR:8606259281 CR:JAGae23599 ) Booting HP-UX from CD-ROM media using the HLDS half-height DVD drive (A8068A) yields a High Priority Machine Check (HPMC). This is caused by a controller initiated reset on the IDE bus before the configuration of each IDE channel is complete. Resolution: Configuration of each IDE channel is now done before the IDE bus is reset by the driver. This prevents the driver from accessing the drive too soon after the reset. ( SR:8606269368 CR:JAGae33603 ) The IDE interface driver was not designed to handle forwarded IOs. On any system with IO forwarding enabled, the driver accesses the IDE drive more often to poll for status. In some instances this can cause data corruption when reading from a Teac DVD slimline IDE drive (A8069A) on multi-processor systems. When an IDE CD/DVD drive is becoming ready on a multi-processor system and the IDE interface driver is handling a forwarded IO, the driver does not properly read the ATAPI interrupt register. The IDE interface driver will then incorrectly wait for the IDE drive to become ready for data transfer without obtaining the current drive status. The drive becomes ready, but the IDE interface driver never acknowledges the state change. This can cause a user application to hang for approximately fifteen minutes, at the end of which the driver times out the IO and returns an error to the user application. Resolution: IO forwarding turned off for the IDE interface driver. PHKL_26409: ( SR:8606237066 CR:JAGae06113 ) Booting HP-UX from CD-ROM media using the HLDS half-height DVD drive yields a High Priority Machine Check (HPMC). This is caused by the driver's failure to allow enough time for the drive to recover after a hardware reset. Resolution: The driver now waits longer to access the drive following a hardware reset. ( SR:8606251613 CR:JAGae17678 ) Installing HP-UX from CD-ROM media using the HLDS half-height DVD drive yields a device busy error. This is caused by the driver's failure to allow enough time for the drive to recover after a hardware reset. Resolution: The driver now waits longer to access the drive following a hardware reset. PHKL_24282: (SR: 8606198839 CR: JAGad68028) The OS needs to be enhanced to support CD-RW drives. Resolution: This patch enables support for CD-RW drives. PHKL_22644: IDE driver buffers data, including disk capacity information. The buffer is not cleared when there is no media in the CD-ROM drive. Resolution: IDE driver now checks for the "No media present" condition, and resets the disk capacity to zero. PHKL_22031: The "side" driver was originally delivered as part of a hardware enablement patch and is not part of the core operating system. To include this driver in the kernel during an operating system install or upgrade it is necessary for a SD-UX control script to insert the "side" reference into the system file before a kernel is built. Resolution: The patch was repackaged with customized versions of the postinstall and postremove control scripts included. PHKL_20822: (SR: 8606110752 CR: JAGab83500) Under some conditions, it is necessary to re-read the IDE registers. The existing driver code to retry the reads was determined to be incomplete, causing the symptoms noted above. This could be reproduced under heavy CD-ROM activity, but would rarely if ever show up in normal use. Resolution: The existing code to retry register reads was improved to include reading a non-IDE register during the reread loop, and an additional register will now be reread when needed. Note: only systems with IDE drives need this patch. PHKL_20154: ( SR: 8606107507 DTS: JAGab77743 ) This patch delivers new functionality to support SuperIO functionality on the B1000, C3000, and J5000 workstations as well as future HP-UX 11.00 workstations which support the SuperIO interface. This patch enables the IDE/ATAPI functionality on the SuperIO IDE interface. The functionality delivered by this patch will not function on these systems unless the core SuperIO patch (PHKL_20152 or its superseding patch) is also present. However, if this patch is installed on the system without the core SuperIO patch also being installed, absolutely no change will occur to the system. Resolution: The patch was repackaged with customized versions of the postinstall and postremove control scripts included.
