Error "could not populate devices directory" During a mksysb Clone
OS Level: AIX Version 4.1.5
While creating a mksysb clone, the user received the following error:
could not populate devices directory
The following steps were taken:
These steps resulted in the display of the contents of the dummy toc
- Booted from the install CD-ROM.
- Inserted the mksysb tape.
- From the displayed menu, selected option 3, Start Maintenance Mode
for System Recovery.
- Selected option 3, Access Advanced Maintenance Functions.
- Entered the following commands:
tctl -f /dev/rmt0 rewind
dd if=/dev/rmt0 fskip-2
This content indicates that the tape is not a mksysb tape but rather
a Sysback system image tape. The error is occurring because the fourth
image of a Sysback system image tape is a backup of the Sysback
installation and maintenance files.
The shell script bi_main performs the main operating system
installation. This script expects the image to be in backup/restore
format, this is interpreted as the image of the system and begins
running. However, all that is restored are the Sysback installation
and maintenance files. The /etc/objrepos directory is not
available for bi_main to populate the devices directory.
To run this type of clone, a mksysb tape is needed. To clone using
Sysback, contact an IBM Support Specialist.
