The priority of rebuild versus I/O operations is specified with 1..5, where 1 is 
more resources and 5 the least. Setting the value to 1 gives maximum 
processing time to rebuilds rather than I/O. Setting the value to 5 gives 
maximum processing time to I/O rather than rebuilds. 

Enabling and disabling rebuild schedules is only for 9000 models, however 
the rebuild rate (1..5) applies to all controllers. 

7000- and 8000-series controllers have only one setting for Task Rate; it 
applies to both rebuild and verify rates. This rate is not persistent following a 
reboot for 7000- and 8000-series controllers.

/c

 set verify=enable|disable|1..5

This command enables or disables all verify background task slots on 
controller /cx and (when enabled) sets the priority of verification versus I/O 
operations. When enabled, verify tasks will only be run during the time slots 
scheduled for verifies. If a verify is taking place when the schedule is enabled, 
it will be paused until the next scheduled time. 

The priority of verify versus I/O operations is specified with 1..5, where 1 is 
more resources and 5 the least. Setting this value to 1 implies fastest verify, 
and 5 implies fastest I/O. 

Enabling and disabling verify schedules is only for 9000 models, however the 
verify rate (1..5) applies to all controllers. 

                                      

/c

 set selftest=enable|disable

 

[task=UDMA|SMART]

This command enables or disables all selftest tasks or a particular 
selftest_task (UDMA or SMART). 

Enabling and disabling selftest is only for 9000 models. 7/8000 models have 
the same internal schedule, but it is not viewable or changeable.

 //localhost> /c0 selftest=enable task=UDMA

enables UDMA selftest on controller c0.

When enabling the verify schedule you must also remember to enable the 

autoverify setting for the units to be verified. For more information see 
“/cx/ux set autoverify=on|off” on page 68.
