caplam Posted April 10 Share Posted April 10 Hello, Recently i repurposed my main server into a backup server with a plus license. The array has 7 disks with no parity. Cache pool is 2x1Tb ssd btrfs pool. I have a strange issue (see the picture). 2 disks are visible both as array disks and unassigned devices. I can't stop the array. 1 disk has read errors. For the other one with issue i don't know. Perhaps a connection. Before repurposing the server disks had no problems. 2 disks are in a sas das (disks 6&7). The other ones are on internal sata ports. z620-diagnostics-20240410-1357.zip Quote Link to comment
Solution JorgeB Posted April 10 Solution Share Posted April 10 Looks like an issue with the Intel SCU controller, unless all the disks using it share a power splitter or something, if you have another controller to connect those devices I would try it. Quote Link to comment
caplam Posted April 10 Author Share Posted April 10 thanks. It looks like it's the right diag. Changed the port to the ahci controller for theses 2 disks (they were the only ones on the scu controller). No issue at booting and currently running diskspeed benchmark. Never had a glitch in years with the scu controller. Luckily i don't need these 4 ports. What drove you to scu in diags ? I made the same deduction but only when i saw that the 2 drives were the only one attached to the scu. Quote Link to comment
