6.8.4 Alternate Disk Installation Enhancements (4.3.2) In this section, the enhancements made at the AIX 4.3.2 introduction are given. 6.8.4.1 New alt_disk_install 4.3.2 Usage Listed below are the new command formats for the various tasks given. Create Alternate Disk: mksysb (-d) or clone (-C): alt_disk_install {-d | -C} [-i ] [-s ] [-R ] [-D] [-B] [-V] [-r] [-p ] [-L ] [-b ] [-I ] [-l ] [-f ] [-F ] [-e ] [-w ] [-n] [-P ] Determine Volume Group Boot Disk (-q): alt_disk_install -q Rename Alternate Disk Volume Group (-v): alt_disk_install -v Wake-up Volume Group (-W): alt_disk_install -W Put-to-sleep Volume Group (-S): alt_disk_install -S Clean Up Alternate Disk Volume Group (-X): alt_disk_install -X [] 6.8.4.2 Scenarios for Command Enhancements To see which disks belong to the original rootvg volume group after the system has been rebooted from the alternate disk, an entry has been added to the database, so that when the system is rebooted from the alternate disk, and the lspv command is executed, a volume group name old_rootvg will be listed for the original rootvg disks. # lspv hdisk0 00006091aef8b687 old_rootvg hdisk1 00076443210a72ea rootvg This volume group will be set to NOT varyon at reboot, and should ONLY be removed with: # alt_disk_install -X old_rootvg # lspv hdisk0 00006091aef8b687 None hdisk1 00076443210a72ea rootvg New function was added to the -X flag to allow for specified volume group name information removal. It is recommended that you always use alt_disk_install -X when removing any information about an alternate volume group (altinst_rootvg, old_rootvg, and so on). alt_disk_install manages changes to the ODM that are required. Using exportvg or reducevg could cause serious problems to your system (like removing base entries in /etc/filesystems). alt_disk_install -X and alt_disk_install -X will not remove actual data from the 126 AIX Version 4.3 Differences Guide
volume group. Therefore, you can still reboot from that volume group, if you reset your bootlist. To see which disk is the boot disk, of the old_rootvg volume group, after a reboot from the alternate disk, the -q flag has been added to alt_disk_install to determine the boot disk, from the user specified disk and its associated volume group. The command syntax is: # alt_disk_install -q Given any disk in the volume group, and the command will return the actual boot disk (contains hd5), for that volume group. # lspv hdisk0 00006091aef8b687 old_rootvg hdisk1 00076443210a72ea rootvg hdisk2 0000875f48998649 old_rootvg # alt_disk_install -q hdisk0 hdisk1 In this case, the boot disk for old_rootvg is actually hdisk1. Therefore, you could reset your bootlist to hdisk1 and reboot to the original rootvg volume group. # bootlist -m normal hdisk1 # reboot -q This query will work on any volume group that has a boot (hd5) logical volume. Different names for altinst_rootvg are now possible for the case that a user would want to have multiple alternate disks on one system (one with 4.3.2, one with 4.2.1, and so on). The -v flag was added to allow non-rootvg volume group names to be changed. The syntax for this is: # alt_disk_install -v For example, on a 4.2.1 system, run alt_disk_install to restore a 4.3.2 mksysb to hdisk2 and hdisk3. Execute alt_disk_install, with the -v flag, to rename the altinst_rootvg volume group name. Then, on the same system, run alt_disk_install to clone the 4.2.1 system to hdisk4 and hdisk5. Finally, rename the cloned altinst_rootvg. # lspv hdisk0 00006091aef8b687 rootvg hdisk1 00000103000d1a78 rootvg hdisk2 000040445043d9f3 None hdisk3 00076443210a72ea None hdisk4 0000875f48998649 None hdisk5 000005317c58000e None # alt_disk_install -d /dev/rmt0 hdisk2 hdisk3 ... # lspv hdisk0 00006091aef8b687 rootvg hdisk1 00000103000d1a78 rootvg hdisk2 000040445043d9f3 altinst_rootvg hdisk3 00076443210a72ea altinst_rootvg hdisk4 0000875f48998649 None hdisk5 000005317c58000e None # alt_disk_install -v alt_disk_432 hdisk2 # lspv System Management and Utilities 127
