RELEASE NOTES
1. Patch SG0002442 Release Note This release note describes patch SG0002442 to IRIX 6.2. This patch replaces patch SG0002074, SG0001607, SG0001284.1.1 Supported Hardware Platforms This patch contains bug fixes for all hardware platforms supported by IRIX 6.2.1.2 Supported Software Platforms This patch contains bug fixes for the IRIX 6.2 tape driver (tpsc). The software cannot be installed on other configurations. This patch requires patch SG0002172 (or its successor) to be installed This patch replaces patches SG0002074, SG0001607, SG0001284.1.3 Bugs Fixed by Patch SG0002442 This patch contains fixes for the following bugs in IRIX 6.2. Bug numbers from Silicon Graphics bug tracking system are included for reference. o 526083 Open on stat device breaks I/Os to "regular" one. o 528263 Recommended block size for magstar MP is wrong.1.4 Bugs Fixed in Patches Replaced by Patch SG0002442 o 313334 Include files sys/mtio.h and sys/param.h are now made FORTRAN safe. o 354033 tpsc didn't correctly handle detection of LEOT (early-warning). This has been fixed for all DLT drives, STK 9490 (Timberline), STK SD3 (Redwood), IBM 3590 (Magstar) and Exabyte 8mm devices. For those applications wanting to support ANSI labels (see 'man mtio') a new definition has been added to the status word (mt_dposn field of the mtset struct) returned by a MTIOCGET ioctl() call, to allow those applications to differentiate between LEOT and PEOT. See 'man mtio'. o 355446 Block position number reported by the 'mt' command for STK 9490 (Timberline), STK SD3 (Redwood) was incorrect. o 365072 On some devices, if the tape was positioned at EOD, a read operation was not returning error code ENOSPC. o 365300 For variable block devices, the value of recommended blocksize reported in the mtblkinfo structure returned by the MTIOCGETBLKINFO ioctl(), was not consistent. o This patch has support for all OEM DLT drives (DLT2x00, DLT4x00 and DLT7000). Additionally, support is added to allow a DLT7000 to operate in native or DLT4000 density. The device nodes used to select the densities are - tps?d?xxx.7000 - DLT7000 native, no compression - tps?d?xxx.7000c - DLT7000 native, compression - tps?d?xxx.4000 - DLT4000 native, no compression - tps?d?xxx.4000c - DLT4000 native, compression - tps?d?xxx = tps?d?xxx.7000 - tps?d?xxxc = tps?d?xxx.7000c xxx = one of 's nrs ns nrns nr sv nrsv nsv v nrnsv nrv' o 373904 "nr" device would rewind if not used for more than 5 minutes. o 395620 This patch fix the problem of var writes failing while application in particular mediad holds stat open active on the tape device. See also bug 468004 - a duplicate. o 456309 Added an ioctl (MTILIMODE) which enables/disables suppression of ILI on overlength conditions. o 467316 This corrected the typo which has been preventing the driver from reading the tape through a fixed sizes device if a size of the fixed tape device block was set to a different value than the size of the record on tape. o 467719 This fixed the problem with ODD sized WIDE WRITES ON TAPE. Since it is impossible to send odd number of bytes to a wide device, HBA driver is forced to send one byte, to make it even. As a result of this special case handling in HBA driver, resid count in the IO request block was set to -1, even though in reality the device received exectly as much as it asked for. This is passed to an upper driver (tpsc). The new code checks after each IO block returns back from HBA if it fits the description above and if yes - resid count is fixed to 0. o 467735 This is to fix an erroneous handling of partial reads of small var size records using large fix read requests. As a result it was possible for an application to read more data off the tape than it was actually written there. o 474252 This fixed the problem with stale tape state after MTSEEK o This patch has support for SONY AKEBONO drive (SONY GY-10). o 481862 Current block position reporting is fixed for 3590 drivers o 485594 The problem with close() fails on end of tape for exabyte drives is fixed. o 497666 The problem with ioctl not failing if given illegal space addresses is fixed. o 499453 High speed locate was "slow" on STK SD3 and 9490 -- upper 10 bits of block number were being stripped off. o 502518 Add support for the SONY DDS3 DAT drive, in the same manner and degree as for the Seagate (formerly Archive ARDAT) DDS drives, including audio over scsi. o 507744 When writing a tape on a timberline drive, the MTIOCGET ioctl returns zero for the position for the second half of the tape.1.5 Subsystems Included in Patch SG0002442 This patch release includes these subsystems: o patchSG0002442.eoe1_sw.unix It replaces the tpsc driver. The tpsc driver is a loadable driver, so there is no need to reboot after installing this patch. Use the command: "/sbin/ml unld 144" to be sure that the previous tape driver is no longer loaded, if you want to be sure you use the one from this patch. o patchSG0002442.eoe1_man.unix1.6 Installation Instructions Because you want to install only the patches for problems you have encountered, patch software is not installed by default. After reading the descriptions of the bugs fixed in this patch (see Section 1.3), determine the patches that meet your specific needs. If, after reading Sections 1.1 and 1.2 of these release notes, you are unsure whether your hardware and software meet the requirements for installing a particular patch, run inst. The inst program does not allow you to install patches that are incompatible with your hardware or software. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your Software Installation Administrator's Guide to bring up the miniroot form of the software installation tools. Follow these steps to select a patch for installation: 1. At the Inst> prompt, type install patchSGxxxxxxx where xxxxxxx is the patch number. 2. Initiate the installation sequence. Type Inst> go 3. You may find that two patches have been marked as incompatible. (The installation tools reject an installation request if an incompatibility is detected.) If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 4. After completing the installation process, exit the inst program by typing Inst> quit1.7 Patch Removal Instructions To remove a patch, use the versions remove command as you would for any other software subsystem. The removal process reinstates the original version of software unless you have specifically removed the patch history from your system. versions remove patchSGxxxxxxx where xxxxxxx is the patch number. To keep a patch but increase your disk space, use the versions removehist command to remove the patch history. versions removehist patchSGxxxxxxx where xxxxxxx is the patch number.1.8 Known Problems INST SUBSYSTEM REQUIREMENTS No Requirements Information Available. INST SUBSYSTEM CHECKSUMS These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line): 22293 2 patchSG0002442 56302 42 patchSG0002442.eoe_man 24131 768 patchSG0002442.eoe_sw 29001 8 patchSG0002442.idb INST SUBSYSTEM FILE LISTINGS The following lists the files which get installed from each subsystem in the patch:
