Hi, We're running 4.6.2. We had no remote access. The failure was on the swap partition and it would not respond to TCP connections. The physical console was still fine. The worst of this is we tested hot swapping drives, rebuilding arrays in the background, everything and were thinking we were in good shape. We have a half-dozen of these boxes with identical hardware configuration in production now and cannot afford to have them lock up if a drive fails. I agree about IDE-RAID, but we are on a tight budget and need only reliability, not performance, from these machines. - Mike On 12/9/02 2:31 PM, "Alexander Langer" <alex@big.endian.de> wrote: > Thus spake Michael DeMan (michael@staff.openaccess.org): > >> We are using Promise RAID controllers built on motherboards.
