Set Commands
These commands allow you to set certain controller and unit specific
parameters as described below. The set command can be used to set its rebuild
rate, and enable or disable cache. For information about viewing information
about the controller and units, see the “Info Commands” on page 85.
Syntax
set rebuild c<c> <1..5>
set cache c<c> u<u> on|off
set verify c<c> <1..5> (Note: 9000 only)
set autoverify c<c> u<u> on|off (Note: 9000 only)
set overwriteECC c<c> u<u> on|off (Note: 9000 only)
Parameters
rebuild
- sets the rebuild rate (per controller basis) and also sets the
initialize rate.
cache
- enables or disables caching on a per array or unit basis for RAID
1, 5, and 10 arrays.
verify
- sets the verify rate (per controller basis)
autoverify
- enables or disables the automatic verification (per unit basis)
overwriteECC
- enables or disables the ignoreECC function dring rebuild
(per unit basis)
Note:
A value of 1 indicates slowest I/O and fastest rebuild rate. A
value of 5 indicates fastest I/O and slowest rebuild. Interim values
scale linearly (e.g., a value of 3 indicates a rebuild rate half as fast
as a rebuild of 1).
set rebuild
cid
1..5
This command allows you to set the priority of rebuild in relation to I/O
operations. Setting this value to 1 implies that rebuilds should consume more
resources (cpu time, I/O bandwidth) to complete its task. Conversely, setting
this value to 5 implies that I/O has higher priority and rebuild. This command
applies to 7000, 8000, and 9000 models. For the 7/8000 series, the rebuild rate
also applies to the verify and background scrub tasks.
set verify
cid
1..5
This command allows you to set the priority of verification in relation to I/O
operations. Setting this value to 1 implies fastest verify, and 5 implies fastest
I/O. Note that This feature only applies to 9000 series controllers.
