By default, the sybsyntax installation scripts install the sybsyntax database on the device that is designated as the default database device.
If you have not used sp_diskdefault to change the status of the master device (which is installed as the default disk) or to specify another default device, the scripts install sybsyntax on the master device. Sybase recommend that you do not use this configuration because sybsyntax uses valuable space, which is best left available for future expansion of the master database.
