[DSM can't see hard drive IN PVE with 1.02b loader]

I try to install dsm under proxmox ve with 1.02b loader,  sata0 is the loader and sata1 should be the system disk.

 

When I boot it, sata0 works well and  I can visit the install web page. But the web page says NO HARDISK FOUND ON DS3615xs

 

using qm terminal I find " Exit on error [1] DISK NOT INSTALLED... " . I doubt it's the root cause. But I don't know what should I do ?

 

the last msg is DiskStation login:   but I don't know username and password
