H740p mini and SAS Intel SSD PX05SMB040

Oh
Any linux command to do this instead of unplugging all of them and finding a HBA controler card

Thats the problem though isnt it; "linux" wont see the drive until you do.

Damn you are so good
I find this and it's probably the reason why the drive doesn't worki

As I mentioned before, so much drama with PERC controllers in HBA-mode. Just swap them out for a Dell HBA330 true IT-mode storage controller. Your future self will thank you. They are cheap to get.

 

[Ertu]

I got a 330 but don't know if it's a HBA .. should i flash it to it-mode ?

 

[Ertu]

Ok i ordered this one finally from Ebay
Dell PERC HBA330 mini mono 12G SAS Storage Controller SSD JBOD pass-through

 

[Ertu]

I think i must do the 512b trick to be able to use the drives ?

Don't forgot to flash the HBA330 to the latest firmware from dell.com/support

I compile this utility to format SAS drives to 512-bytes or do a low-level format https://github.com/ahouston/setblocksize

You'll need to install the sg3_utils package.

While doing that, might as install sdparm package and enable the write cache on the SAS drive as root running the following command:

sdparm -s WCE=1 -S /dev/sd[x]

Where 'x' is the drive letter.

I should do it to every drive ? have 10 of them

 

[Ertu]

You are so helpfull guys, thanks a lot

 

[Ertu]

Ok done but seems that the first drive isn't enabling cache can you confirm ?

root@px5:~# sdparm -s WCE=1 -S /dev/sg0

After a reboot i can see all drives on PVE and can do a ZFS raidz2 right now, you are really awesome
But is the cache enabled ?

 

[Ertu]

Ok find it
To confirm write cache is enabled as root, run: sdparm --get=WCE /dev/sd[X]

1 = on
0 = off

 

[Ertu]

Ok the raid doesn't work with the first one disk, the NETAPP one but ok with the 9 others.
What kind of SAS SSD, the cheap one can you advise me, need 400Gb by disk at least, 600gb will be great

 

[Ertu]

Ok iswapped back to 740P mini then i think i kill the server


DS1 and DS3 fix
DS5 and DS6 blinking.

No start, no bios, no screen, nothing :/
