For what it's worth, here is my experience. Hope it helps you, and
anyone else searching for solutions to the problems I have encountered...
Our New Server
==============
(+ Lessons learnt along the way)
++++++++++++++++++++++++++++++
Motherboard: Asus P4S8X-X
CPU: Intel Pentium 4 2400MHz
Memory: 2 x 512Mb PC2700
+was supposed to be 3x512Mb but the motherboard can't handle 3xPC2700
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Network: 3Com 3c905C-TX/TX-M [Tornado]
Do NOT use the onboard LAN - performance is diabolical!
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Additional controller cards:
2xPromise Ultra133 Tx2 PCI-IDE cards
1xPromise Ultra66 PCI-IDE card
Do note use 3 identical Promise IDE cards, either system will not
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
boot or there will be i/o errors!
++++++++++++++++++++++++++++
Disks
=====
(In addition to system disk)
10 x Maxtor 6Y060L0 60Gb
attached to onboard ide and Promise Ultra133 cards
4 x Maxtor 4A250J0 240Gb disk
attached to Promise Ultra66 cards
Software:
RedHat 9
kernel 2.4.20
Boot parameters modified as follows:
Edit /boot/grub/menu.lst
and append
ide2=noautotune ide3=noautotune ide4=noutotune ide5=noautotune
ide6=noautotune ide7=noautotune
to the line
kernel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/
this avoids errors of the type:
++++++++++++++++++++++++++++
hdh: dma_intr: bad DMA status (dma_stat=75)
when accessing the disks on the Promise cards
Thereafter formatted disks/created raid arrays/started raid/made
filesystem no problem. Four 240Gb disks formatted as one big disk via
raid0!
(/dev/md8 Size=989GB)
Tape drive: Spectra Logic 2000 (a.k.a. TreeFrog) attached via
Adaptec AIC-7892A SCSI card
Use mtx version 1.2.17rel to drive the robot, more recent
versions cause problems (author informed).
