Why does my AIX database not restart following system recovery?

Why does my AIX database not restart following system recovery?
After a reinstall of my AIX system from a backup, the database application will not start.

exec(): 0509-036 Cannot load program /home/sybase/sybase.12/ASE-12_0/bin/dataserver because of the following errors:

ANSWER

This problem is caused by the async io device not configured and available. This device is configured after the install using the chdev command, but this particular device requires a reboot for the configuration to take effect. The solution is to reboot the system and the configuration will take effect. The database should start properly from that point forward.
