Hello!
I faced of with problem with work array B140i driver when incorrect power off.
In our office often happened problems with power, power backup not help.
When server switch on after incorrect power off, i get message about not found boot drive.
I load OS (Windows Server 2012R2) in recovery mode and sее drive array not found. Then i do driver loading (command drvload from shell) and execute startup problem recovery procedure. After this manipulation OS startup normally. But next day problem repeated.
How can I solve problem?
I have other (non HP server) and they startup without any problem after incorrect power off.
