To display specific scheduled tasks, issue the showsched <schedule_name>|<pattern>
command, where:
• <schedule_name> is the name of the schedule to display.
• <pattern> displays all schedules that match the pattern.
For a complete list of options available for the showsched command, see the HP 3PAR Command
Line Interface Reference and the HP 3PAR CLI Help.
Scheduling Tasks
To create a scheduled task, issue the createsched <command> <task_schedule>
<schedule_name> command, where:
• <command> is the name of the CLI command to be initiated. The CLI command must be one
of the commands listed in Table 13 (page 137).
• <task_schedule> is a crontab-style argument that specifies when the CLI command is
initiated. You can use the minute, hour, day-of-month, month, and day-of-week format, or use
one of the special entries to schedule when the CLI command is initiated.
