clexecd
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 (like the cluster shutdown command).This daemon registers with failfastd so that a failfast device driver will panic the kernel if this daemon is killed and not restarted in 30 seconds.
cl_ccrad
This daemon provides access from userland management applications to the CCR.It is automatically restarted if it is stopped.
cl_eventd
The cluster event daemon registers and forwards cluster events (such as nodes entering and leaving the cluster). There is also a protocol whereby user applications can register themselves to receive cluster events.The daemon is automatically respawned if it is killed.
cl_eventlogd
cluster event log daemon logs cluster events into a binary log file. At the time of writing for this course, there is no published interface to this log. It is automatically restarted if it is stopped.
failfastd
This daemon is the failfast proxy server.The failfast daemon allows the kernel to panic if certain essential daemons have failed
rgmd
The resource group management daemon which manages the state of all cluster-unaware applications.A failfast driver panics the kernel if this daemon is killed and not restarted in 30 seconds.
rpc.fed
This is the fork-and-exec daemon, which handles requests from rgmd to spawn methods for specific data services. A failfast driver panics the kernel if this daemon is killed and not restarted in 30 seconds.
rpc.pmfd
This is the process monitoring facility. It is used as a general mechanism to initiate restarts and failure action scripts for some cluster framework daemons (in Solaris 9 OS), and for most application daemons and application fault monitors (in Solaris 9 and10 OS). A failfast driver panics the kernel if this daemon is stopped and not restarted in 30 seconds.
pnmd
Public managment network service daemon manages network status information received from the local IPMP daemon running on each node and facilitates application failovers caused by complete public network failures on nodes. It is automatically restarted if it is stopped.
scdpmd
Disk path monitoring daemon monitors the status of disk paths, so that they can be reported in the output of the cldev status command. It is automatically restarted if it is stopped.

Prevent new nodes from entering
scconf –a –T node=.
Put a node into maintenance state
scconf -c -q node=
Note: use the scstat -q command to verify that the node is in maintenance mode, the vote count should be zero for that node.
Get a node out of maintenance state
scconf -c -q node=
Note: use the scstat -q command to verify that the node is in maintenance mode, the vote count should be one for that node.
Admin Quorum Device Quorum devices are nodes and disk devices, so the total quorum will be all nodes and devices added together.You can use the scsetup GUI interface to add/remove quorum devices or use the below commands.
Adding a device to the quorum
scconf –a –q globaldev=d11
Note: if you get the error message "uable to scrub device" use scgdevs to add device to the global device namespace.
Removing a device to the quorum
scconf –r –q globaldev=d11
Remove the last quorum device
