RAID status monitoring HPE Smart Array E208i-p SR Gen10

It shouldn’t be this hard, but I can’t figure out how to monitor the RAID status with the HPE Smart Array E208i-p SR Gen10, in a HP ProLiant DL360 Gen10 in Linux.

• I can’t find a file in /proc or /sys.
• arcconf says: Controllers found: 0.
• ssacli controller all show says: Error: No controllers detected.
• Same for HP SSA CLI: Error: No controllers detected.

Edit: it was a bit confusing because this server has two RAID controllers, but neither work so far, so the question is the same.

This is the lspci -v output of the E208i-p:

  11:00.0 Serial Attached SCSI controller: Adaptec Smart Storage PQI 12G SAS/PCIe 3 (rev 01)
  Subsystem: Hewlett-Packard Company Smart Array E208i-p SR Gen10

This of the P408i-a:

Edit: on a slightly order server, with ‘Hewlett-Packard Company Smart Array Gen9 Controllers (rev 01) / Hewlett-Packard Company P440’, the hpssacli tool does work.
