Configuring SAMS with LifeKeeper
server may fail when a switchover to the backup server occurs. Note that
the SAMS Recovery Kit does not require the switchable IP address to
have an MX record on the DNS server.
Protected Files, Directories and Services
The SAMS Recovery Kit protects the following configuration and data
directories:
• /etc/mail
• /etc/md
• /var/md/store
If not located on a shared file system, the MTA and MSP queue directories
(e.g., /var/spool/mqueue, /var/spool/clientmqueue) must be manually moved
to the shared file system and linked to the original location on each server
before the hierarchy is created.
Any files that are not in the default locations as listed above (i.e. mailstore,
transaction log path and the Sendmail switch data directory) must be
manually linked to files/directories on the shared file system.
Note: The shared file system should always have the most up-to-date
configuration files.
The SAMS Recovery Kit will monitor and protect the following services
whether they are configured on default or non-default ports:
• sendmail (default port 25, configurable via /etc/mail/sendmail.cf)
• pop3d (default port 110, configurable via /etc/md/store/ms.conf)
• imapd (default port 143, configurable via /etc/md/store/ms.conf)
• samshttpd (default port 8890, configurable via /etc/mail/switch.ini)
• perl sdap-server.pl (default port 9000, configurable via
/etc/mail/switch.ini)
