I have a DELL Latitude 6510 with dual SAMSUNG SSD operating in a RAID1 configuration. I replaced the DVD with the second SSD. Every time the laptop is operating off the battery, IRST puts the array into Power Saving Mode and sets the mirror drive OFFLINE degrading the volume.
I have disabled LPM. My power settings are set to NEVER for the hard drive when on battery power.
How can I force the IRST to leave the mirror drive online even when on battery power?
The battery settings imposed by your computer manufacturer does not have anything to do with the volume integrity of your RAID 1. There might be some settings you need to adjust in the computer BIOS that I am not familiar with. I recommend contacting http://www.dell.com/support/home/us/en/19?c=&l=&s= Support | Dell US and check for any settings that may help on this matter.
