# Quorum S

erver Parameters. Use the SGQSHPSIMLNX_HOST,

SGQSHPSIMLNX_POLLING_INTERVAL,

# and SGQSHPSIMLNX_TIMEOUT_EXTENSION parameters to define a quorum

server.

# The SGQSHPSIMLNX_HOST is the host name or IP address of the system

# that is running the quorum server

process. The

# SGQSHPSIMLNX_POLLING_INTERVAL (microseconds) is the interval at which

# ServiceGuard checks to make sure the quorum server is running.

# The optional SGQSHPSIMLNX_TIMEOUT_EXTENSION (microseconds) is used to

increase

# the time interval afte

r which the quorum server is marked DOWN.

# The default quorum server timeout is calculated from the

# ServiceGuard cluster parameters, including NODE_TIMEOUT and

# HEARTBEAT_INTERVAL. If you are experiencing quorum server

# timeouts, you can adjust these

parameters, or you can include

# the SGQSHPSIMLNX_TIMEOUT_EXTENSION parameter.

# For example, to configure a quorum server running on node

# "SGQShpsimlnxhost" with 120 seconds for the

SGQSHPSIMLNX_POLLING_INTERVAL and to

# add 2 seconds to the system ass

igned value for the quorum server

# timeout, enter:

# SGQSHPSIMLNX_HOST SGQShpsimlnxhost

# SGQSHPSIMLNX_POLLING_INTERVAL 120000000

# SGQSHPSIMLNX_TIMEOUT_EXTENSION 2000000

# Cluster Timing Parameters (microseconds).

# The NODE_TIMEO

UT parameter defaults to 2000000 (2 seconds).

# This default setting yields the fastest cluster reformations.

# However, the use of the default value increases the potential

# for spurious reformations due to momentary system hangs or

# network load spikes

# For a significant portion of installations, a setting of

# 5000000 to 8000000 (5 to 8 seconds) is more appropriate.

# The maximum value recommended for NODE_TIMEOUT is 30000000

# (30 seconds).
