234 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.2
Problems in 3DM2 and 3BM
A 3ware RAID controller does not show in the list of controllers
You may not have the most recent driver for your controller, the driver may
not be loaded, or you may not have the most recent version of the CLI or
3DM2.
To find out the driver version currently installed, see “Determining the
Current Version of Your 3ware Driver” on page 170
Current drivers and software are available for download on the LSI website at
http://www.lsi.com/channel/ChannelDownloads .
When booting a system, a drive is not showing up in the startup
screens, in 3BM, or in 3DM2
This could be due to one or more of the following:
• Defective cable
• Defective drive
• Defective enclosure or drive slot
• Poorly seated drive
• Poorly connected power cable
• Poorly connected data cable
• Defective connector on the 3ware controller
If a drive that previously showed up in 3DM2 or 3BM does not show up, try
the following:
1 Power the system down, then reseat the drive in the slot, reseat the data
cable, and reseat the power cable.
2 Power the system back up.
3 If the drive still does not show up in 3DM2 or 3BM, then swap that drive
with a drive that is showing up.
4 If the drive now shows up, and drive you swapped it with does not, then
the drive is OK. The problem could be the controller connector, the cable,
the power connector, or the enclosure or drive slot.
5 Change each of these things, one at a time
• Try a different connector on the controller
• Try a different data cable
• Power the drive with a different power connector from the power
supply
• Try connecting the drive directly to the motherboard, bypassing the
enclosure or drive slot
