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. The example described in “Creating the cluster input file” specifies raw device raw11 as the quorum disk:
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.
See dataserver under “Changes
to commands” section in the “System Changes” chapter
of the User Guide for more information about
the dataserver parameters.
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
