I want to run the smartctl self tests to check the health of the drives in my RAID array (PERC 5/i). The array is on sda and comprises six drives. I can check the status using

sudo smartctl /dev/sda -d megaraid,0 -a

And I see that SMART is available and enabled on all the drives. I have tried to run self tests using

 sudo smartctl /dev/sda -d megaraid,0 -t short

and

 sudo smartctl /dev/sda -d megaraid,0 -t long

I have also tried it on all of the drives 0-5. No matter what I try, when I run:

 sudo smartctl /dev/sda -d megaraid,0 -l selftest

I always get the same result, which seems to always report that I have never run a self test.

 /dev/sda [megaraid_disk_00] [SAT]: Device open changed type from 'megaraid' to 'sat'
 ===START OF READ SMART DATA SECTION ===
 SMART Self-test log structure revision number 1
 No self-tests have been logged.  [To run self-tests, use: smartctl -t]

From what I read, I should have no problem running the short and long self tests on the array while it is mounted. Does anyone else have experience running these tests on a PERC 5/i raid array who could lend some insight into what is causing the problem?
