Error "0505-102 alt_disk_install: mkvg has returned an error"
OS Level: AIX Version 4.3.x
When running a clone to another disk using the alt_disk_install
command, mkvg returns the error 0505-102 alt_disk_install:
mkvg has returned an error.
Following are guidelines for using the
- The fileset that installs alt_disk_install is
- There are two options in using the alt_disk_install command:
- Install a mksysb on an alternate disk.
With this option, a mksysb tape or image is loaded onto an alternate
disk and serves as a rootvg.
- Clone the rootvg to an alternate disk.
With this option, the current rootvg is copied to another disk.
- The main purpose of making duplicate rootvgs is for short-term
backup/recovery procedures. It can be useful, during a system upgrade,
to have a backup from which to quickly recover if necessary.
For example, if the rootvg is on hdisk0 and the altinst_rootvg
is on hdisk1, in an upgrade failure, the user can run the bootlist
command to change the bootdisk to hdisk1 and reboot off of that disk.
- IBM does not support making a clone of the rootvg with the
alt_disk_install command to take that hdisk to another system.
A mksysb must still be made to tape or, alternatively, the
Network Install Manager (NIM) can be used.
- Once the alternate rootvg has been made
on the other disk with the alt_disk_install command, do NOT
export the volume group manually under any circumstances. This will
corrupt the rootvg, removing all the stanzas from /etc/filesystems.
In the event this does occur, there is a solution. Ensure that the
altinst_rootvg (the name given to the cloned rootvg) disk does not
display a volume group with the lspv command. Run the following:
# imfs rootvg
This will re-populate the /etc/filesystems file. If the system is
rebooted before this command can be run, the RAM /etc/filesystems
file will have to be copied to the hard disk rootvg
/etc/filesystems file. A new boot image should be made and the
bootlist set back to the proper disk.
- There can only be one altinst_rootvg imported on the system at a
time. An altinst_rootvg cannot be created on two separate disks. If
this is attempted, the following error displays:
0505-102 alt_disk_install: mkvg has returned an error
0516-360 getvgname: The device name is already used; choose
a differennt name
0516-862 mkvg: Unable to create volume group
If this error is received, the alt_disk_install cannot be run
until the current alt_disk_install is removed (explained in the
- Exporting the alt_disk_install altinst_rootvg volume group
The alt_disk_install creates the volume group altinst_rootvg. This is
properly removed with the following command:
# alt_disk_install -X
This will fix the Object Data Manager (ODM) tricks that were performed and remove the volume group.
