18.2 About Tasks
Tasks are a mechanism by which users can track selected long-running system operations on
the InServ storage system.
Tasks are created in one of two ways:
■ By a user (or script) issuing certain InForm CLI commands, such as the tunealdvv
command.
■ By the system initiating certain automated or scheduled processes, such as the periodic
resynchronization of remote copy volumes groups.
Table 18-2 on page 18.4 provides a complete list of the operations that utilize the task
management features described in this chapter.
18.2.1 Task IDs
Each task is identified by a task ID. When a task is started via the InForm CLI, the system
displays the task ID as part of the command output.
For example, when you issue the
tunealdvv command via the InForm CLI, a task is started in
order to track the progress of the
tunealdvv operation. The task ID is indicated in the output
for the
tunealdvv command, as shown in the following example:
In the above example,
Task 454 is started as part of the tunealdvv operation.
cli% tunealdvv -p -nd 2,3 testvol
Task 454 started.
