Patch_SG0002184_Release_Note This release note describes patch SG0002184 to IRIX 5.3. Patch SG0002184 replaces patches: SG000176, SG0000658, SG0000742, SG0000763, SG0000783, and SG0001283. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for all platforms supported by 5.3 and 5.3 variants such as 5.3XFS. 1.2 Supported_Software_Platforms This patch contains bug fixes for IRIX 5.3, all versions. The software cannot be installed on other configurations. 1.3 Bugs_Fixed_by_Patch_SG0002184 This patch contains fixes for the following bugs in IRIX 5.3. Bug numbers from Silicon Graphics bug tracking system are included for reference. 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. 1.4 Bugs_Fixed_in_Patches_Replaced_by_Patch_SG0002184 o 241273: fuser should identify user of a tape device as in 4.0.5 o 287623: 5.3 and 6.1 do not properly support the Exabyte 8505XL tape drives o 299115: Add support for STK9490, STK SD3 and IBM NTP. o 243108: mt setblksz would fail with the errno EINVAL. o 243659: On systems with multiple IO4 controllers, the controller number would be reported incorrectly in warning and error messages for controllers other than 0. o 244525: Use of drives that supported variable block sizes in fixed block mode would sometimes panic the kernel. o 250171: DLT tape drives were checking the wrong field to determine if the drives needed to be cleaned, and could therefore incorrectly report that the drive needed cleaning. - 2 - o 296618: Exabyte tape drives with compression sometimes return errors when reading compressed data. The tpsc driver has been modified to retry commands when such errors occur. o 326321: b_bcount would on occasion be changed by tpsc potentially causing VM leaks. 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 362347: Some alert error message printed by tpsc were associated with an invalid controller ID number. 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' - 3 - o This patch has support for SONY AKEBONO drive (SONY GY-10). o This patch replaces Patch SG0000783 and as such has support for the IBM Magstar (NTP), STK 9490 (Timberline) and STK SD3 (Redwood) tape drives, for IP19 and Challenge S platforms. However, for such support, hinv rollup Patch SG0001157 (or its successor) and one of the SCSI rollup Patches SG0000852 or SG0001327, for IRIX 5.3 and IRIX 5.3xfs respectively, (or their successors) must be installed on the system prior to installing this patch. 1.5 Subsystems_Included_in_Patch_SG0002184 This patch release includes only this subsystem: o patchSG0002184.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 patchSG0002184.eoe1_man.unix 1.6 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. 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 - 4 - where xxxxxxx is the patch number. 2. Select the desired patches for installation. 3. Initiate the installation sequence. Type Inst> go 4. You may find that two patches have been marked as incompatible. If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 5. After completing the installation process, exit the inst program by typing Inst> quit 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.
