List, I have a problem I just can't seem to figure out. linux 2.4.27 can see the logical drive just fine: megaraid: v2.10.3 (Release Date: Thu Apr 8 16:16:05 EDT 2004) megaraid: found 0x101e:0x1960:bus 0:slot 3:func 0 scsi0:Found MegaRAID controller at 0xf89c3000, IRQ:17 megaraid: [6.62:1.03] detected 1 logical drives. megaraid: supports extended CDBs. megaraid: channel[0] is raid. megaraid: channel[1] is raid. megaraid: channel[2] is raid. megaraid: channel[3] is raid. scsi0 : LSI Logic MegaRAID 6.62 254 commands 16 targs 7 chans 7 luns scsi0: scanning scsi channel 0 for logical drives.

The card is a LSI ATA megaraid controller sold by dell as a CERT card. I have the latest firmware on it. At this point I'm not sure what to do. Any ideas on how to make the newer megaraid driver see the logical drive? schu - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
