| |
Ladies and Gentlemen:
I remember reading a proposal to do something similar to what I desire. Has anything taken place w.r.t. that suggestion?
My problem:
I have an AHA-3985 3-channel SCSI-2 RAID controller. It seems to be equivalent to three separate AHA-2940's with three AIC7870 chip channels and the AIC7810 chip is unused. I have several (narrow) SCSI drives, a CD-ROM, a CD-RW, and an 230MB MO drive. The machine is fine and working hard at the moment, but the problem is that my MO drive is in an external enclosure and is sometimes used with other machines.
* Since only the A channel on the AHA-3985 has an external 50 pin connector, I have to connect my MO to the A channel.
* Since I want to split up my hard drives between the channels AND the kernel always scan the A channel before the B and C channels, the MO appears as /dev/sdb when it is in use, and pushes my next hard drives into /dev/sdc and /dev/sdd. But When the MO is not there, the hard drives become sdb/sdc.
* Is there some way I could rearrange the names of devices? I feel particularly compelled because I want to experiment with soft RAID devices.
* Rest of my stuff: dual PPro 200, SuperMicro P6DNE, 192MB, cheap SB16 clone sound, cheap generic NE2000 ISA NIC.
