Start the Recall Daemon

The recall daemon recalls migrated files from storage to your local file system. A recall daemon can recall only one file at a time; however, you can run more than one recall daemon at the same time. To set the minimum and maximum number of recall daemons that you want to run at one time, use the minrecalldaemons and maxrecalldaemons options in your dsm.sys file. The minimum number of recall daemons that you can run at the same time is one. The default is three. The maximum number of recall daemons that you can run at the same time is 99. The default is 20. See Minrecalldaemons and Maxrecalldaemons for more information about these options.

The maximum number of recalls that you can set depends on the number of concurrent recalls that normally occur on your system. If all recall daemons are busy, another file cannot be recalled until a recall daemon is available. If a frequently-used application opens several files at the same time, and that application uses all available recall daemons because all files are migrated, increase the value that you set on the maxrecalldaemons option. If a recall daemon is unable to start another process that is attempting to access a migrated file, that process cannot continue until a recall daemon is available.

The master recall daemon starts automatically when you mount your file system and add space management to it. If a recall daemon is not running, enter the dsmrecalld command to start one.

When you change the option values that the recall daemons use, the new values are not effective until you restart your system, or you stop and restart the master recall daemon.
