Requirements for Using Sybase ASE with Raw I/O

In order to use the Sybase ASE Recovery Kit with raw I/O, the following requirements must be met:

• The Linux OS must support raw I/O devices. For most distributions this support was included in the 2.4 kernel, but there are some distributions that support raw I/O on a 2.2 kernel.

• All raw I/O devices must be bound to a shared disk partition. The number of database devices (devspaces) that will be located on raw I/O devices determines the exact number of raw devices and shared disk partitions required. Refer to the Installation Guide Adaptive Server for Linux for guidelines for creating database devices on raw devices.

• The version of the Sybase ASE software must support the use of raw I/O devices.
