Active/Standby Scenario 

The gray arrows represent dangling links (i.e. the files on Server 2 are 
linked to the shared storage device, but the shared device is not 
mounted on Server 2. Therefore, the links on Server 2 are not active).

 

During the extension of the SAMS resource instance to the backup server 
(i.e. Server 2), the Recovery Kit symbolically links the SAMS configuration 
and data directories /etc/md, /etc/mail, and /var/md/store to the versions on 
the shared file system. Note: The existing directories on Server 2 are saved 
with a .LK extension. 

IMPORTANT: If your specific SAMS configuration requires any other files 
to be LifeKeeper-protected, these files must be manually moved to the shared 
file system and linked back to their original locations on each server after the 
extension of the SAMS resource hierarchy.

The gray files and directories are symbolically linked to files on the 
shared storage device.  

The black arrows represent active symbolic links (i.e. the files on Server 
2 are actively linked to the shared storage device after the resource is 
switched or failed over).
