LED identification of drives

[Suresh R]

I'd like to know which chassis are reliable/work out of the box for identifying drives by led. The main criteria is that the system should not have to be brought down to check serial numbers and then swap drives during failure.

I have looked at the online guides but this information does not seem present. Is it just that the chassis must support the sas2ircu command? I am considering Supermicro with LSI2208/2308.

Thanks
Suresh

I have a SC846-E1 and I am using a SLI 9211-8i. Peronsally I identified which hdd was in which bay when I did the badblocks testing. I then noted it in Freenas on each drive. I then printed it out and have it in with my rack. Once the server is hosting live data I plan on laminating it.

Ex:
da0 SN##### bay 13
da1 SN##### bay 2
da2 SN##### bay 0
etc

I just wrote all the serial numbers down in a diagram of my chassis before install :)

Please note the device labels (adaX, daX, ...) can change from reboot to reboot, the only two things who don't change are the serial number and the GPTID ;)

<--- Mind blown.

So you are saying my spare drive could change too?

Someone revoke his FreeNAS aware status please :p

Yes, any drive can change. It actually happened to me once, da3 and da4 were swapped, then the next reboot they were like before...

Man you guys are mean... :( *goes into the corrner to cry*

@Fuganater, you are jumping to conclusions.

@Fuganater, you are jumping to conclusions.

What?

 

[solarisguy]

What?

Create a volume (pool) with a hot spare. Using CLI execute
zpool status yourpoolname

What do you see?
