dsmd(1M) monitors domain status and operating system (OS) heartbeat for up to 18 domains on Sun Fire 15K/E25K systems, and up to nine domains on Sun Fire 12K/E20K systems.

dsmd automatically recovers the domain and handles domain-related hardware errors. In the event of a domain hang, dsmd resets the domain, collects CPU registers and hardware configuration dumps, and saves them to two files. This daemon also passes to efhd(1M) any automatic diagnosis (AD) information related to a domain stop.

All domain state changes are monitored and logged in domain-specific log files if the message level is INFO; otherwise there is no log for a state change.

This daemon is started automatically by the ssd(1M) daemon. Do not start it manually from the command line.

dsmd logs the following events and attempts to recover from them:

• Domain boot failure
• Error reset
• Solaris OS hang
• Domain panic
• Domain reset/reboot
• DStop
• Boot/panic/error_reset_sync timeout
