[Solved] Hard drives order question

[spyderx]

I have three 2 TB HDs connected to AOC-SASLP-MV8.  The order from AOC is:

 

0: Hitachi 2TB

1: Hitachi 2TB

2: Samsung 2TB

 

When I boot into Unraid and tries to assign the drives, the pulldown menu lists the HDs in reverse order as I listed below.

 

sdb: Samsung

sdc: Hitachi

sdd: Hitachi

 

Is there a reason why Unraid chose it this way?  I would like to have my HD order the way AOC configures it.  I want my 1st Hitachi HD as parity then followed by the data drives.  That way all the data drives will be in sequence with no break in between as a parity drive.

 

Thanks

Paul.

It does not matter... and you should not care.

 

unRAID does not pick the drive order, it is determined by the Linux kernel and there is virtually no control over the detection process.

 

Just assign the drives were you want them inside the unRAID software and go with it.

They are assigned in the order in which they present themselves as being ready to the linux OS.  The designations can even change from one boot to the next if two disks initialize in nearly the identical times (but different sequence)

 

Apparently, the Samsung initializes faster.

Thanks for the explanations prostuff1 & Joe L.  Since I can't do anything about it, I'll take both your advice and just go with it.
