Troubleshooting
The system hangs during the boot
process after installation.
The system hangs during the boot
process after installation.
Some operating systems do not load
in a computer with a MegaRAID
Express 500 adapter.
One of the hard drive in the array
fails often
Pressed <Ctrl> <M>. Ran
Megaconf.exe and tried to make a
new configuration. The system
hangs when scanning devices.
Multiple drives connected to
MegaRAID Express 500 using the
same power supply. There is a
problem spinning the drives all at
once.
Pressing <Ctrl> <M> or running
megaconf.exe does not display the
Management Menu.
At system power-up with the
MegaRAID Express 500 installed,
the screen display is garbled or does
not appear at all.
Cannot flash or update the
EEPROM.
Problem
Make sure the SCSI BIOS on the motherboard
has been disabled.
Make sure the MegaRAID Express 500
adapter card is installed in the proper PCI
expansion slot. It must be installed in the
RAID Upgrade PCI slot.
Check the system BIOS configuration for PCI
interrupt assignments. Make sure some
Interrupts are assigned for PCI.
Initialize the logical drive before installing the
operating system.
Check the drive error counts using Power
Console 500.
Format the drive.
Rebuild the drive
If the drive continues to fail, replace the drive
with another drive with the same capacity.
Check the drives IDs on each channel to make
sure each device has a different ID.
Check the termination. The device at the end
of the channel must be terminated.
Replace the drive cable.
Set the drives to spin on command. This will
allow MegaRAID Express 500 to spin two
devices simultaneously.
These utilities require a color monitor.
For proper cache memory operation, you must
install at least 16 MB of memory in
MegaRAID Express 500.
You may need a new EEPROM.
