Dumping Databases with Devices That Are Mirrored

At the beginning of a dump database, the SAP ASE server passes Backup Server the primary device name of all database and log devices. If the primary device has been unmirrored, the SAP ASE server instead passes the name of the secondary device. If any named device fails before the Backup Server completes its data transfer, the SAP ASE server aborts the dump.

If a user attempts to unmirror any of the named database devices while a dump database is in progress, the SAP ASE server displays a message. The user executing the disk unmirror command can abort the dump or defer the disk unmirror until after the dump is complete.
