NetApp FAS2520 new spare HDD was detected as SAS with RPM 15000 while others are FSAS with RPM7200

Recently I met that FAS2520 HDD failed issue (0a.00.1 and 0a.00.8 failed, 0a.00.3 in maintenance testing) and no available spare HDD. I order 3 new HDDs with same PN, and set spares to new 0a.00.1 and 0a.00.8 successfully. But system did not auto rebuilding. And detect 0a.00.1 and 0a.00.8 as SAS with RPM 15000 while others are FSAS with RPM7200. What is the best next plan? Thanks in advance for your advice.

add pictures of old (labeled old 0a.00.8) and new HDD

Where did you get the disks from? Maybe the gray market biting you in the rump?

 How about just pasting output instead of pictures
