Log files
Various Storage Mirroring Recover components (Storage Mirroring service, Replication
Console, Failover Control Center, and the Command Line Client) generate a log file to
gather alerts, which are notification, warning, and error messages. The log files are
written to disk.
Each log file consists of a base name, a series number, and an extension.
● Base Name—The base name is determined by the application or process that is
running.
Component Log File Base Name
Storage Mirroring Recover dtlog
Replication Console mc
Failover Control Center fcc
Command Line Client dtcl
● Series Number—The series number ranges from 1 to 999. For example, Storage
Mirroring Recover begins logging messages to dtlog1. When this file reaches its
maximum size, the next log file will be written to dtlog2. As long as log messages
continue to be written, files dtlog3, dtlog4, dtlog5 will be opened and filled. When
the maximum number of files is reached, which by default is 5, the oldest file is
deleted when the sixth file is created. For example, when dtlog6 is created, dtlog1
is deleted and when dtlog7 is created, dtlog2 is deleted. When file dtlog999 is
created and filled, dtlog1 will be re-created and Storage Mirroring Recover will
continue writing log messages to that file. In the event that a file cannot be
removed, its number will be kept in the list, and on each successive file remove,
the log writer will attempt to remove the oldest file in the list.
● Extension—The extension for each log file is .dtl.
