Patch Name: PHKL_23282 Patch Description: s700_800 11.04 (VVOS) PC floppy cumulative patch Creation Date: 01/02/01 Post Date: 01/02/09 Hardware Platforms - OS Releases: s700: 11.04 s800: 11.04 Products: N/A Filesets: OS-Core.CORE2-KRN,fr=B.11.04,fa=HP-UX_B.11.04_32,v=HP OS-Core.CORE2-KRN,fr=B.11.04,fa=HP-UX_B.11.04_64,v=HP Automatic Reboot?: Yes Status: General Release Critical: Yes PHKL_23282: CORRUPTION PHKL_22776: CORRUPTION Category Tags: defect_repair general_release critical corruption Path Name: /hp-ux_patches/s700_800/11.X/PHKL_23282 Symptoms: PHKL_23282: Patch PHKL_22776 may not install correctly on 64 bit only systems with floppy drive. PHKL_22776: Port base HP-UX patch PHKL_22377 for VVOS. Based on PHKL_22377: During a write to a floppy disk, the potential may exist for the floppy disk controller to incorrectly transfer the last byte of data in a sector if the computer is simultaneously experiencing activity on the I/O bus sufficient to cause a significant delay in the transfer of that byte, but no other byte. Specifically, the next to last byte could be re-written in the place of the last byte. This potential error may not be reported to the user. Defect Description: PHKL_23282: Patch PHKL_22776 had a packaging error where a 32 bit object file was put in a 64 bit only fileset resulting in possible installation problems of this patch on 64 bit only systems with floppy drive. Resolution: Packaged the correct 64 bit object file with the 64 bit fileset. PHKL_22776: Port base HP-UX patch PHKL_22377 for VVOS. Resolution: Ported HP-UX patch PHKL_22377. Based on PHKL_22377: It is claimed that a design error exists in certain floppy disk controller technology that creates the potential for data corruption or data loss during the transfer of data to or from a floppy disk or tape device that utilizes a floppy disk controller. Specifically, it is alleged that this potential exists when the floppy disk controller is transferring the last byte of a sector and only if the computer is simultaneously experiencing activity on the I/O bus sufficient to cause a significant delay in the transfer of that byte, but no other byte. HP is unaware of any customer actually experiencing this error. Nevertheless, HP is offering a software patch to customers to eliminate the possibility that their computers could experience such an error. Resolution: The software patch eliminates the possibility that a HP computer could experience the error described above. HP is recommending that customers visit HP's website at http://hp.com/go/fdcpatch or you can call HP's customer Service Center at 1-800-742-9729 in order to determine if HP recommends downloading the patch.
