I have a PowerEdge 2900 Server that seems to lose its boot settings to boot from the PERC 6i Controller. In the DRAC logs, it stated battery problems so I replaced the PERC 6i controller battery. I cleared the logs after replacing the battery.
Just for testing, I loaded ESXi 5.1 on it which loaded successfully, and I rebooted the server several times, turned the server off for 10 minutes and then booted it and all seemed well. I then turned the server off for a week, and came back, and the server doesn't know to boot from the RAID Controller.
The startup boot sequence goes through the normal process and sees the RAID Controller, and 1 array and 1 virtual drive, but then stops and says "no Boot Device Available"
Dell BIOS 2.7.0
Perc Controller BIOS 6.3.3.0002
Baseboard Management 2.50
Remote Access Controller 1.45 Build 9.01.16
Just for testing 3 drives with RAID 5. I have tried 2 drives mirrored RAID 1 as well.
Can't figure out why the system is losing the information to boot to the RAID Controller.
