How does N4F / BSD 9.2 name devices/harddrives?
I am currently setting up my new NAS with a IBM M1015 (IT mode) with 6x 4tb drives. I noticed the device names does not coincide with the physical port order.
For example, I want da0 to be the first harddrive connected to sata port 1 and da1 to be the second etc. But it seems the order right now is random. When plugging in a new drive reorders everything.
What am I doing wrong?
Thanks in advance for any advice!

Re: IBM M1015 port numbers and device name
there is no assigned order.
the first detected drive becomes da0 regardless if its connected to the first or last port.

Re: IBM M1015 port numbers and device name
thankyou for the info b0ssman. I've resorted to labeling the drive bays with the corresponding drive's serial numbers for easy identification.
Is this the usual way it is done? I can't imagine this being practical in an array with a lot of disks.

Yes. It is the best / most accurate way possible to correspond physical hard disks to their order. It is not possible for the system to tell the controller ports and chassis bay order sequence.vandy wrote:thankyou for the info b0ssman.

Yeah, just noticed the same think with my new M1015 flashed to SAS2008 IT mode. Shit, my OCD will drive me crazy with this.
:/
One think I noticed is that the hard drives are ALLWAYS detected in the same order, if that is based on detection it seens odd that the drives will be detected the same way after every reboot...
Maybe we could use labels?

Re: IBM M1015 port numbers and device name
The key part in this situation is that ZFS does not care about drive names.
The pools will know which drives are their members and won't complain....

Yep, ZFS doesn't care and everything works. The issue, if it ever happens, would be when you need to replace a disk...

Re: IBM M1015 port numbers and device name
Ok, after messing around with my pools I got the disks named properly in the pool.
What I did:
zpool export POOL
glabel label disk0 /dev/daX (here is where I had to map the name to the corresponding da)
zpool import -d /dev/label POOL
That was it! Now the pool status show the disk names as are they plugged in my cages!
In Management -> Disks they still show up as their physical names. Maybe we should improve this screen so we could edit the labels there?
