7.5.1.3. Starting the CCS Daemon
When using a CCS server,
ccsd
must connect to it over the network, and requires two parameters on
the
ccsd
command line: the IP address (and optional port number) of the node running
ccs_servd
,
and the name of the cluster.
7.5.1.3.1. Usage
ccsd -s IPAddress [ :PortNumber ] -c ClusterName
IPAddress
The IP address of the node running the CCS server.
:PortNumber
(Optional) The non-default port number. A colon and port number can optionally follow the
IPAddress to specify a non-default port number:
IPAddress:PortNumber
.
ClusterName
Specifies the name of the cluster. The CCS server uses this to pick the correct CCA file that is
named for the cluster.
7.5.1.3.2. Example
This example starts
ccsd
on a node for cluster alpha when using a CCS server with the IP address
shown.
ccsd -s 10.0.5.1 -c alpha
7.5.2. Local CCA Files
An alternative to both a CCA device and a CCS server is to replicate CCA files on all cluster nodes.
Note
Care must be taken to keep all the copies identical.
A CCA file is created using the same steps as for a CCS server. The CCA file is manually copied to
all cluster nodes.
7.5.2.1. Starting the CCS Daemon
When the CCS daemon is started on each node, it must be given the location of the local copy of the
CCA file.
