functionality with use of Linux-provided schedulers such as cron(8) or at(1), or user supplied programs.

/cx/ux stop verify

This command stops a background verification process on the specified unit /cx/ux. Table 9 on page 67 shows the supported matrix as a function of the controller model and logical unit type.

/cx/ux flush

This command allows you to flush the write cache on the specified unit /ux associated with controller /cx. Note that this command does not apply to spare unit types.

/cx/ux set autoverify=onoff

This feature only applies to 9000 series controllers.

This command allows you to turn on and off the autoverify operation on a specified unit /cx/ux during allocated schedule windows.

You can use the show verify command to display the existing schedule windows. By default, autoverify is off.

Auto-verify allows the controller to run the verify function once every 24 hours. If verify schedule windows are set up and enabled, then the controller will ony start an automatic verify task during the schedule time slots. If the verify takes longer than the schedule window, the verify process will be paused and restarted during the next verify schedule window. For additional information, see “Setting Up a Verify Schedule” on page 51.

/cx/ux set cache=onoff [quiet]

This command allows you to turn on or off the write cache for a specified unit /cx/ux. This feature is supported on both 7000/8000 and 9000 models.

By default, cache is on.

Write cache includes the disk drive cache and controller cache. Note that for some configuration types, there is only disk drive cache and no controller cache (for example, JBOD).

The following table shows the supported RAID types for caching as a function of controller model and logical unit type. N/A (Not Applicable) refers to cases where the given logical unit type is not supported on a particular controller model.
