Monitoring a full-server workload
After you have enabled full-server protection, you can monitor the protection from the Full-Server Failover Manager, and you can review the log file generated by Full-Server Failover Manager.
The Protection Status is displayed in the right center of the Full-Server Failover Manager. You can tell the status of your protection from this field.
- Disabled—Protection for the source has not been started. The target must be validated as compatible before you can enable protection.
- Initializing—Double-Take Availability is initializing protection. Once initialization is complete, mirroring will automatically begin.
- Mirroring (% complete)—Double-Take Availability is mirroring the source’s data and system state to the target. The percentage indicates how much of the mirror has been completed. Protection is not complete until the mirror has completed.
- Mirroring (Retrying)—You may see this status message if the target is out of disk space or if Double-Take Availability cannot write to a file on the target. Check the log file on the target for more information.
- Mirroring (Mirror stopped)—You may see this status message if your mirroring process has stopped. Depending on the reason for the stopped mirror, it may restart automatically. Check your Double-Take Availability log file.
- Mirroring (Source Unavailable)—You may see this status message if the source has become unavailable during your mirroring process. You cannot failover until the mirroring process is complete. Correct the issues causing the unavailability, and mirroring will restart automatically.
- Mirroring (Op Dropped)—You may see this status message if the target server cannot apply data to disk. For example, a file may be in use on the target. Check the Double-Take Availability log file on the target for more details.
- Enabled—The mirroring is complete and protection of the source is enabled. In the event the source should fail, the target will be able to stand-in for it.
- Enabled (Source Unavailable)—You may see this message when the target has lost communication with the source. If communication is reestablished before the failover monitoring time expires, the status will update to Enabled. If communication is not reestablished before the failover monitoring time expires, the status will update to Failover condition met.
- Failover condition met—The target has missed too many responses from the source, indicating that the source has failed. At this time, you need to manually determine the status of the source. If the source is still up and users are accessing it, you need to resolve the communications errors between the source and target. Once the communication issue is resolved, the status will update to the appropriate state. If the source is indeed down and users are unable to access it, start failover.
- Failing over (% complete)—The target is in the process of failing over for the source. The percentage indicates how much of the failover has been completed.
- Failed over—Failover is complete. The target will automatically reboot.
In addition to the status displayed in Full-Server Failover Manager, a log file is generated detailing processing information. By default, Full-Server Failover Manager logs basic processing information. To view the log file, select File, Logs, View Full-Server Failover Manager Log. The log file will be opened automatically in Notepad. The log file, FFMLog.log, is located on the in the directory where you installed it. You can clear the log file by selecting File, Logs, Clear Full-Server Failover Manager Log.
