I need to know what are the precaution we should take during quorum server reboot as this quorum server is providing quorum devices to five different solaris two node clusters.
Also let me know do I have to follow below procedure as well before and after reboot of quorum server
Do I have to put those cluster quorum devices in maintenance state by running below command in one node of each of the five clusters before reboot of quorum server
After reboot of quorum server , I need to enable the quorum device on one node of each of the five clusters by running below command

I've recently changed my gateway setting using SMIT. Everything went fine except that the gateway setting kept reverting back to the old one everytime I reboot the server.

quorum_initialize
QUORUM_INITIALIZE(3) Corosync Cluster Engine Programmer's Manual QUORUM_INITIALIZE(3)NAME
quorum_initialize - Create a new connection to the Quorum service
SYNOPSIS
#include <corosync/quorum.h>
int quorum_initialize(quorum_handle_t *handle, quorum_callbacks_t *callbacks, uint32_t *quorum_type);
DESCRIPTION
The quorum_initialize function is used to initialize a connection to the quorum API.
Each application may have several connections to the quorum API. Each application uses the handle argument to uniquely identify the con-
nection. The handle argument is then used in other function calls to identify the connection to be used for communication with the quorum
service.
Every time the voting configuraton changes (eg a node joins or leave the cluster) or the quorum status change, the callback is called. The
callback function is described by the following type definitions:
typedef void (*quorum_notification_fn_t) (
quorum_handle_t handle,
uint32_t quorate,
uint64_t ring_seq,
uint32_t view_list_entries,
uint32_t *view_list
);
The callbacks argument is of the type:
typedef struct {
quorum_notification_fn_t quorum_notify_fn;
} quorum_callbacks_t;
The quorum_type argument is set to:
#define QUORUM_FREE 0
#define QUORUM_SET 1
QUORUM_FREE value means that no quorum algorithm is loaded and that no callbacks will take place.
QUORUM_SET value means that one quorum algorithm is configured and that callbacks will take place.
When a configuration change occurs, the callback is called from the quorum_dispatch() function.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.
ERRORS
CS_ERR_TRY_AGAIN Resource temporarily unavailable
CS_ERR_INVALID_PARAM Invalid argument
CS_ERR_ACCESS Permission denied
CS_ERR_LIBRARY The connection failed
CS_ERR_INTERRUPT System call inturrupted by a signal
CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported
CS_ERR_MESSAGE_ERROR Incorrect auth message received
CS_ERR_NO_MEMORY Not enough memory to completed the requested task
