dsmd(1M) monitors domain status and operating system (OS) heartbeat for up to 18 domains.

dsmd automatically recovers the domain and handles domain-related hardware errors. In the event of a domain hang, dsmd will reset(1M) the domain, collect CPU registers and hardware configuration dumps, and save them to two files.

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

dsmd clients include:

• dxs(1M) -- domain X server daemon
• efe -- Sun Management Center daemon
• osd(1M) -- OpenBoot PROM daemon
• pcd(1M) -- platform configuration database daemon
• esmd(1M) -- environment status monitoring daemon

dsmd is a client of:

• hwad(1M) -- hardware access daemon
• setkeyswitch(1M) -- virtual keyswitch control command

For more information see the System Management Services (SMS) 1.2 Administrator Guide for the Sun Fire 15K/12K Systems.

The following files are supported:

/etc/opt/SUNWSMS/startup/ssd_start

Default startup file for ssd

/var/opt/SUNWSMS/adm/domain_id/

Stores message files and hpost dump files

/var/opt/SUNWSMS/SMS/adm/domain_id/post/

Stores the dstop and hardware configuration dump files

/export/home/sms-user/xir_dump/

Stores xir dump files for all domains
