Smart Array "Mixed mode" makes drive letter change UN-CONTROLLABLE AND UN-WANTED
System configuration:
- Proliant ML350 Gen10 with Smart Array P816i-a
- HDD: 8TB SAS
- OS: CentOS 7.4
Symtoms:
Unwanted and un-modifiable behaviour of Smart Array "Mixed mode". Drive letter for OS system drive (Logical drive created by RAID setup) will change when new unassigned drives are inserted into the system.
It seems to be related to the "Mixed mode" behaviour. Unfortunately, according to the "HPE Smart Array SR Gen10 Configuration Guide" (part no. 882375-002), the mixed mode of Port settings is "cannot be disabled".
Here is self explained terminal output log:
