Building the Master and Quorum Devices

Create the quorum and master devices on raw devices on the shared-disk storage.

When creating the quorum device, use the same device name and major and minor numbers on all machines. Each raw device must be accessible from each node using the same path. This example uses raw11 for the quorum disk.

For example:

dataserver
...

--quorum-dev /dev/raw/raw11

The syntax for creating Cluster Edition master and quorum devices is:

dataserver
--cluster-input= cluster_input_filename_and_path
--quorum-dev= quorum_device_and_path 
--master-device-size= master_device_size 
--logical-page-size= page_size 
--instance= instance_name
--buildquorum

where:

--master-device-size=<size spec> – specifies the size of the master device.
--cluster-input=<cluster input file> – loads the cluster configuration specified in the input file onto the quorum device.
--quorum-dev= path_to_quorum_device – specifies the full path to the quorum device.
--instance=instance_name – specifies the name of an instance.
--logical-page-size= page_size – specifies the page size.
--buildquorum – specifies that a new quorum device should be built.

Create the master and quorum devices using dataserver. This example creates an instance named “ase1” that is configured for 4K pages, a master device of 500MB, and a quorum device:

/opt/sybase/ASE-15_0/bin/ dataserver\ 
--quorum-dev=/dev/raw/raw11\
--instance=ase1
--cluster-input=/opt/sybase/mycluster.inp 
--master-device-size=500M
--logical-page-size=4k
--buildquorum

See the Cluster Users Guide and Utility Guide for more information about the dataserver utility.
