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
This command applies to the 7000, 8000, and 9000 models controllers.
Example:
//localhost> /c1 show rebuildrate
/c1 Rebuild background task rate = 4 (Faster Rebuild; slower I/O)
Related commands:
/cx set rebuildmode=
/cx set rebuildrate=<1...5>

show selftest
9000 series controllers support background tasks and 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 7 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 67.
Selftest activity provides two types of selftests; UDMA (Ultra Direct
Memory Access) and SMART (Self Monitoring Analysis and Reporting).
Both self tests are checked once each day by default.
UDMA self test entails checking the current ATA bus speed (between
controller and attached disk), which could have been throttled down during
previous operations and increase the speed for best performance (usually one
level higher). Possible speeds include 33, 66, 100 and 133 Mhz.
Note:
UDMA mode is applicable only for PATA (parallel ATA) drives on earlier
3ware controllers. It is not applicable for SATA or SAS drives.
