Hello!

I have a Debian 3.1, kernel 2.4.36, with ATA133-Raid controller on board:
RAID bus controller: Promise Technology, Inc. PDC20276 (MBFastTrak133 Lite)
(rev 01)

There are 2 HDDs connected to this controller in RAID 1 (mirror)
configuration. They are visible as /dev/ataraid...

/dev/ataraid/d0p1 on / type ext3 (rw,errors=remount-ro) itd.

Everything works fine, execpt this, that both disks are on
the same channel, one master, one slave.
I would like to switch one to another channel to improve performance.
(Of course I mean second channel on Promise RAID controller).

Can I just power off computer and move one HDD to another channel?
Will it work withour any array rebuilding, adn data loss?

Mirek
