keep the data and index files synchronized but would be expensive in processing time. The extra processing was avoided by keeping some unused space in each variable length field. By padding the fields with spaces, they can shrink or grow within limits, and a record can be updated without having to rearrange the file and rebuild the index. Record level lock Locking is now done at the record-level instead of the file-level by using advisory locks for updates. This prevents having to read and write the entire file. There is no longer a need for the /etc/olastlog file, and it has therefore been removed. 6.6.4 mkpasswd Command The index system is created when the mkpasswd command is executed. It deletes any existing outdated indexes (except for the lastlog index) and builds new indexes. New flags allow complete control of this enhancement. 6.7 Microcode Packaging In versions of AIX prior to Version 4.3, some IBM microcode entities resided in filesets that were prerequisites of other filesets. This meant that our OEM customers had to ship these filesets even if they were not required. In some cases, customers who developed their own additional features preferred to use their own microcode instead of the IBM-supplied microcode. In order for these OEM customers to replace the IBM microcode, it was necessary for them to modify AIX. To rectify this situation, the following filesets were modified to remove the IBM microcode so that our OEM customers can ship AIX without having to perform any changes: • bos.sysmgt.nim.master • devices.mca.8fc8 – Common token-ring Software – Token-Ring high-performance adapter diagnostics – Token-Ring high-performance adapter microcode – Token-Ring high-performance adapter software • devices.mca.df9f – Direct-Attached disk diagnostics – Direct-Attached disk software • devices.mca.ffe1 – 128-port asynchronous adapter diagnostics – 128-port asynchronous adapter microcode – 128-port asynchronous adapter software The devices.mca packages were a source of error because even though some systems do not have an MCA bus, other rspc packages regarded these MCA packages as prerequisites. The files needed by the other rspc packages were moved out of the devices.mca.* packages and into a separate fileset. 120 AIX Version 4.3 Differences Guide
6.8 On-line Alternate Disk Installation The alt_disk_install command gives users another way to update AIX to the next release or maintenance level without having to schedule an extended period of system downtime. The update can be performed in two ways: mksysb image Installing a mksysb requires a 4.3 mksysb image or 4.3 mksysb tape. The alt_disk_install command is called, specifying a disk or disks that are installed in the system but are not currently in use. The mksysb is restored to those disks, such that, if the user chooses, the next reboot will boot the system on a 4.3 system. Note: If needed, the bootlist command can be run after the new disk has been booted, and the bootlist can be changed to boot back to the older version of AIX. Cloning Cloning allows the user to create a backup copy of the root volume group. Once created, the copy may be used either as a back up, or it can be modified by installing additional updates. One possible use might be to clone a running production system, then install updates to bring the cloned rootvg to a later maintenance level. This would update the cloned rootvg while the system was still in production. Rebooting from the new rootvg would then bring the level of the running system up to the newly installed maintenance level. If there was a problem with this level, simply changing the bootlist back to the original disk and rebooting would bring the system back to the old level. Currently, you can run the alt_disk_install command on 4.1.4 and higher systems for both of these functions. The bos.alt_disk_install.rte fileset must be installed on the system to do cloning to an alternate disk, and the bos.alt_disk_install.boot_images fileset must be installed to allow a mksysb install to an alternate disk. The mksysb image that is used must be created before installation and include all the necessary device and kernel support required for the system on which it is installed. No new device, or kernel support, can be installed before the system is rebooted from the newly-installed disk. Note: The level of mksysb that you are installing must match the level of the bos.alt_disk_install.boot_images fileset. At this time, 4.3.2, 4.3.1, and 4.3.0 mksysb images are supported. AIX 4.3.1 boot images are available only on the 4.3.1 installation media. When cloning the rootvg volume group, a new boot image is created with the bosboot command. When installing a mksysb image, a boot image for the level of mksysb and platform type is copied to the boot logical volume for the new alternate rootvg. When the system is rebooted, the bosboot command is run in the early stage of boot, and the system will be rebooted again. This is to synchronize the boot image with the mksysb that was just restored. The system will then boot in normal mode. System Management and Utilities 121
