Mirroring the Master Device

If you choose to mirror the device that contains the master database, in a UNIX environment, you must edit the runserver file for your SAP ASE so that the mirror device starts when the server starts.

On UNIX, add the -r flag and the name of the mirror device:
dataserver -d /dev/rsd1f -r /dev/rs0e -e/sybase/install/errorlog

For information about mirroring the master device on Windows, see the Utility Guide.
