The manual IS sloppy. missing - characters in the syntax
Tryijng to figure out -Val syntax
megacli AdpPRSetDelay -Val -aN|-a0,1,2|-aALL
- /home/drew/bin/MegaCli -AdpPRSetDelay 0 -a0
Invalid input at or near token -AdpPRSetDelay
Tried sticking a - in front of the zero. Doesn't make much sense, tried it anyway, didn't help.
Seriously, I get that you are frustrated, been there myself.
I don't have any of our LSI's actually running at the moment, but it makes sense to me if the Patrol Read is disabled, you get an error configuring it. Just a guess...
What does a -AdpPR -Info -a0 yield?
