Prerequisites for creating a
cluster.
- Install Cluster Edition.
- Allocate enough storage space for the required database
devices. Only raw partitions rather than file system-based devices are
supported. Ensure that the raw partitions are accessible from each node using
the same access path. These database devices are created if they do not exist:
- master device
- sybsystemprocs device
- sybsystemdb device
- quorum device (no actual database visible from within SAP ASE is created)
- Allocate
one device for the local temporary database on each node. For example, if you are creating a three-node cluster, then you need three individual raw partitions for temporary databases—one for each node.
- Create the appropriate number of devices, such as data and log,
for your user databases. Create the devices only once. For example, if you have
a four-node cluster and you are connected to instance, when you run a disk init command for datadev1 on ASE1, the instances ASE2, ASE3, and ASE4 recognize,
and can write to datadev1 once disk init completes.
- Start the agent from your installation directory.
