Controller Object Commands

/cx show rebuildrate
The /cx show rebuildrate command shows the current rebuild task rate of the
specified controller. The rebuild task rate sets the rebuild execution priority
relative to I/O operations.
This task rate is in the range of [1..5], where 5 denotes the setting of fastest
background task and slowest I/O, as follows:
5 = fastest rebuild; slowest I/O
4 = faster rebuild; slower I/O
3 = balanced between rebuild and I/O
2 = faster I/O; slower rebuild
1 = fastest I/O; slowest rebuild
Example:
//localhost> /c1 show rebuildrate
/c1 Rebuild background task rate = 4 (Faster Rebuild; slower I/O)
Related commands:
/cx set rebuildmode=<adaptive|lowlatency>
/cx set rebuildrate=<1..5>
/cx show rebuildmode
/cx show selftest
Background tasks allow you to schedule a regular time when they occur.
Selftest is one of the supported background tasks. Rebuild and verify are other
background tasks for which there are separate schedules. Migrate and
initialize are additional background tasks that follow the same schedule as
rebuild. For each background task, up to seven time periods can be registered,
known as slots 1 through 7. Each task schedule can be managed by a set of
commands including add, del, show and set a task. Background task
schedules have a slot id, start-day-time, duration, and status attributes.
For details about setting up a schedule for background selftest tasks, see
“Setting Up a Selftest Schedule” on page 61.
Selftest activity provides Self Monitoring Analysis and Reporting (SMART).
Self tests are checked once each day by default.
SMART activity instructs the controller to check certain SMART-supported
thresholds by the disk vendor. An AEN is logged to the alarms page if a drive
reports a SMART failure.
