Recovery was performed on physical PAM appliance, but it seems not restored to lastest backup version.
So changed boot sequence to secondary SSD. And it is able boot up.
But after change boot sequence back to primary SSD, PAM is not able to boot up anymore.
It seems PAM is not able to load grub with error 22(guess has something to do with partition).
Suggest connect to console and perform recovery again.

But it seems cannot get to grub, instead get into BIOS.
Is primary SSD corrupted? How can we recover from this situation?
