Monitoring and controlling tasks

The VxVM task monitor tracks the progress of system recovery by monitoring task creation, maintenance, and completion. The task monitor lets you monitor task progress and modify characteristics of tasks, such as pausing and recovery rate (for example, to reduce the impact on system performance).


VxVM supports this feature only for private disk groups, not for shared disk groups in a CVM environment.

The tasks that are created on the system are logged for diagnostic purposes in the tasklog file in the /etc/vx/log/ directory. This file logs an entry for all task-related operations (creation, completion, pause, resume, and abort). The following is a sample log entry:
