[SOLVED] Adding harddrive sdb becoms sdc

jocef · 01-13-2011, 12:52 PM

In my server I have 2 harddrives. sda and sdb
Sata port 1 = sda
Sata port 2 = sdb

But after i add a new harddrive the new structure looks like this:

Sata port 1 = sda
Sata port 2 = sdc
Sata port 3 = sdb

When i was putting in one more discs i couldn´t boot becuse the sda was not longer the disc on port 1. No boot device.

What is deciding what dev id my disc get?

I´m running slackware 13.0, motherboard ASUS M2N68-AM PLUS

Yes, the order can change like that. Which is why it is a good idea to set /etc/fstab to mount by UUID or LABEL instead of device path.
