[NTLUG:Discuss] Help with Promise FastTrak Tx2000

[gan hawk]

Hi,

Yes RAID 5 would be nice but then I would have to add 2 more drives.  Also 
the only reason I am making a raid is for failover. The box is a server and 
it serves its purpose well so I dont want to add more hardware to it.

I am surprised Promise uses software for its RAID stuff. I thought thats 
what the PDC chip onboard was supposed to do!

>>Hello,

>>I want to make a bootable RAID 1 array with promise FastTrak TX 2000. I 
>>installed the card on the computer (an old one which has no special

>>I cannot access the drives as /dev/sda (Promise website tells me that the

>>
>>The kernel has has the following option in the grub:
>>ide0=0x1f0,0x3f6,14 ide1=0x170,0x376,15 ide2=0 ide3=0 ide4=0 ide5=0 ide6=0 
>>ide7=0 ide8=0 ide9=0    noapic
>>
>>I am trying to install this on a redhat 9 system (2.4.20-8)
>>Does anyone else have the same problem or someone got TX2000 working 
>>successfully as a bootable RAID ?
