/cx set verify=advanced|basic|1..5
The /cx set verify=advanced|basic|1..5 command is effectively the same as
the set verify=enabled|disabled command. Setting verify to advanced
enables the advanced Verify Task Schedule, which can include a series of up
to seven days and times. Setting verify to basic creates a weekly schedule
with one specific day and time, and disables the series of scheduling slots
associated with the advanced Verify Task Schedule. For more about the basic
schedule, see “/cx set verify=basic [pref=ddd:hh]”, below.
The priority of verify versus I/O operations is specified with [1..5], where 5 is
more resources and 1 the least. Setting this value to 1 invokes fastest I/O, and
5 invokes fastest verify.
For information on the verify schedule, see “/cx add verify=ddd:hh:duration”
on page 60
/cx set verify=basic [pref=ddd:hh]
Using the verify=basic option allows you to set a basic verify schedule that
starts each week at the same date and time. With verify=basic, you can
specify your preferred day and time, or you can omit the day and time and use
the default of Friday at midnight.
When you set verify=basic, the series of scheduled days and times associated
with the advanced Verify Task Schedule is ignored.
Verify=basic is intended to be used with the autoverify policy for RAID units
to insure that a verification of the unit occurs on a regular basis.
Example:
//localhost> /c3 set verify=basic pref=Fri:23
Setting /c3 basic verify preferred start time to [Fri, 11:00PM]
... Done.
/cx set verifymode=
The /cx set verifymode command sets the verify mode. The verify mode has
two settings: Adaptive and Low Latency.
Verify mode works with the verify task rate (see “/cx set verifyrate=<1..5>”
on page 67).
The Adaptive setting is the default verify mode. It allows the firmware to
adjust the interaction of verify tasks with host I/Os to maximize the speed of
both host I/O and verify tasks.
