Some files must be shared across BEs to preserve normal system operation in an environment with multiple BEs. The following directories are already shared across BEs by IPS:
/var/audit /var/cores /var/crash /var/mail
Within each BE, these directories are symbolic links to the following shared directories:
/var/share/audit /var/share/cores /var/share/crash /var/share/mail
These shared directories are in the VARSHARE dataset, which is a shared dataset mounted at /var/share.
Other data that needs to be shared across BEs can be handled similarly.
