Sun Cluster 3.1 cheat sheet
This is used by cluster kernel threads to executeuserland commands (such as the run_reserve and dofsckcommands). It is also used to run cluster commands remotely (likethe cluster shutdown command).This daemon registers with failfastd so that a failfast devicedriver will panic the kernel if this daemon is killed and notrestarted in 30 seconds.
This daemon provides access from userland management applicationsto the CCR.It is automatically restarted if it is stopped.
The cluster event daemon registers and forwards cluster events(such as nodes entering and leaving the cluster). There is also aprotocol whereby user applications can register themselves toreceive cluster events.The daemon is automatically respawned if it is killed.
cluster event log daemon logs cluster events into a binary logfile. At the time of writing for this course, there is nopublished interface to this log. It is automatically restarted ifit is stopped.
This daemon is the failfast proxy server.The failfast daemonallows the kernel to panic if certain essential daemons havefailed
The resource group management daemon which manages the state ofall cluster-unaware applications.A failfast driver panics thekernel if this daemon is killed and not restarted in 30 seconds.
This is the fork-and-exec daemon, which handles requests from rgmdto spawn methods for specific data services. A failfast driverpanics the kernel if this daemon is killed and not restarted in 30seconds.
This is the process monitoring facility. It is used as a generalmechanism to initiate restarts and failure action scripts for somecluster framework daemons (in Solaris 9 OS), and for mostapplication daemons and application fault monitors (in Solaris 9and10 OS). A failfast driver panics the kernel if this daemon isstopped and not restarted in 30 seconds.
Public managment network service daemon manages network statusinformation received from the local IPMP daemon running on eachnode and facilitates application failovers caused by completepublic network failures on nodes. It is automatically restarted ifit is stopped.
Disk path monitoring daemon monitors the status of disk paths, sothat they can be reported in the output of the cldev statuscommand. It is automatically restarted if it is stopped.
