If HW has multiple QAT devices then only one QAT device will start, because symlinks do not fit for qat_service.
Checking status of all devices. There is 3 QAT acceleration device(s) in the system: qat_dev0 - type: c6xx, inst_id: 0, node_id: 1, bsf: 0000:b1:00.0, #accel: 5 #engines: 10 state: up qat_dev1 - type: c6xx, inst_id: 1, node_id: 1, bsf: 0000:b2:00.0, #accel: 5 #engines: 10 state: down qat_dev2 - type: c6xx, inst_id: 2, node_id: 1, bsf: 0000:b3:00.0, #accel: 5 #engines: 10 state: down
This issue resolves by deleting symlinks c6xx_dev1.conf and c6xx_dev2.conf, and copying c6xx_dev0.conf file to c6xx_dev1.conf/c6xx_dev2.conf
