Disabling automatic rebuild
Q: Can I disable the automatic rebuild behavior?
A: Yes, you can disable automatic rebuild and copyback operations. This is useful for when you want to schedule rebuild behavior, as a rebuild will consume significant controller resources and possibly slow down your production I/O.
Note that these are controller-wide policies, so you will have to always manually start rebuilds and copyback if you disable them.
Use the following commands to disable the automatic rebuild and copyback.
# MegaCli64 -AdpAutoRbld -Dsbl -aN
# MegaCli64 -AdpSetProp -CopyBackDsbl -1 -aN
# storcli64 /cx set autorebuild=off
# storcli64 /cx set copyback=off
