Sybase high availability requires the following hardware and system components:
Two homogenous, networked systems with similar configurations in terms of resources like CPU, memory, etc.
These systems should be equipped with the high availability subsystem package and the associated hardware.
Must have devices that are accessible to both nodes.
The system must have a logical volume manager (LVM) to maintain unique device pathnames across the cluster nodes.
Configure both public and private networks on both the nodes.
Create volumes and volume groups on the multihost disks.
Create one logical host on both the primary and secondary hosts.
Register one or more volume groups on each logical host.
Use third-party vendor mirroring rather than Sybase mirroring for media failure protection.

See your hardware and operating system documentation for information about installing platform specific high availability software.
