I tried the following commands but I keep getting a invalid command error. It seems to properly pick up the correct controller, drive slot, and adapter though. I currently don't have a screenshot of the exact error but it says it can not start the secure erase.
MegaCli -SecureErase Start[Simple[-PhysDrv[252:0,252:1]] -a0
MegaCli -SecureErase Start[Simple] [-PhysDrv[252:0,252:1]] -a0
MegaCli -SecureErase Start[Simple] -PhysDrv[252:0,252:1] -a0
Also tried all the examples above using just one drive slot like below.
MegaCli -SecureErase Start[Simple[-PhysDrv[252:0]] -a0
Spent over an hour trying to figure out the correct syntax from the manual. I am trying to do a secure erase on the SSD since they were heavily used prior so I want to refresh the performance.
