Table 7.1 General Problems and Suggested Solutions (Cont.)
Problem
One of the hard drives in the array fails
often.
Pressed <Ctrl><M>. Ran
Megaconf.exe and tried to make a new

Firmware Initializing...
appears and remains on the screen.
What SCSI IDs can a non-hard disk
device have and what is maximum
number allowed per adapter?
7-2
Suggested Solution
Check the drive error counts using Power Console Plus. See
the MegaRAID Configuration Software Guide for more
information.
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 SCSI 320-0 to spin two devices simultaneously.
These utilities require a color monitor.
You may need a new EEPROM.
Make sure that TERMPWR is being properly provided to
each peripheral device populated channel.
Make sure that each end of the channel chain is properly
terminated using the recommended terminator type for the
peripheral device.
Make sure (on a channel basis) only two types of cables are
connected at any one time.
Make sure that the MegaRAID SCSI 320-0 controller is
properly seated in the ZCR PCI slot.
Non-hard disk devices can accommodate only SCSI IDs 1,
2, 3, 4, 5 or 6, regardless of the channel used. A maximum
of six non-hard disk devices are supported per MegaRAID
SCSI 320-0 adapter.
