Then the SSH keys are regenerated in such a way that they are unique for the new virtual
server. The new root file system is then unmounted, set offline, and detached: In the final
section, the LINUX01 user ID is logged on via XAUTOLOG. Because the shared PROFILE EXEC
detects that the user ID is in a disconnected mode, it carries out an IPL of Linux from minidisk
100.
You may want to SSH into the newly cloned Linux server.
Note: If the clone script fails, you can check that:
► The configuration contains all of the correct information in /etc/clone/
► No other users have links to the clone’s read-write disks
A block diagram of this process is displayed in Figure 9-1.
Figure 9-1 Cloning block diagram
The top of the figure shows the Linux cloner/installation server that is running on the RH6CLONE
user ID. In order to FLASHCOPY or dd, the RH6CLONE user ID requires a LINK to the source
minidisks that RH6GOLD owns and the destination minidisks that LINUX01 owns. The figure
shows that the LINK statement is issued as read-only (RR) for the source and read/write (W) for
the target. The VDISK-based swap spaces at virtual addresses 300 and 301 are defined
in-memory, therefore, they do not need to be copied.
