New sys_eventlevel variable. Use this variable to specify the level of ALOM events that you want ALOM CMT to send to the host server.

New sys_autorestart variable option (reset). Use this option to specify how ALOM CMT should handle expiration of the Solaris watchdog timer (default value: reset).

SSH encryption key type (rsa or dsa) must be specified when using the

Running SunVTS CPU Tests ... Causes Shutdown Due to Watchdog Timeout (CR 6498483)

Coolthreads servers running SunVTS cpu tests have encountered Solaris watchdog timeouts leading to system shutdown.

Workaround: Set the ALOM CMT sys_autorestart variable to none while running SunVTS, so that ALOM CMT issues a warning message but does not reset the server.
