Recovery, Processing | ADIC FileServ Version 4.0 600716 Rev A

Administrative Tasks

	The following messages display at the command line where the
	FileServ command is run to indicate a successful initiation:

	FS0338 FileServ: Request accepted
	FS0277 FileServ complete: FileServ software is
	running
Recovery
Recovery	During FileServ processing, software activity is continually
Processing	recorded in recovery processing files. These files are only used
	during a normal startup. It is important to always attempt a
	normal start after any termination of FileServ.

System Tasks

Contingency Startup

Caution

If files that are migrated to media are actively being transferred to disk at the time an abnormal software termination occurs, a contingency start may corrupt the file data.

A normal start resets the active files to the original state before starting the transfer. Files that are on media only and are being retrieved are reset to being on media only. The request that was active at termination must be reissued by the requestor.

A contingency start is only recommended when a normal start fails. With the exception of initial startup at installation, never attempt a contingency start without first attempting to perform a normal start of FileServ.

Note

A contingency start is used for first-time Initialization of FileServ. For more information, refer to Installing FileServ.

A contingency start initializes certain log files and internal directories but does not perform recovery processing.
