I'm just upgraded LPAR2RRD to a version 6 and switched HMC to Rest API to test it.
But I founded that this method doesn't work for Server-9117-MMA's IBM servers.
I have 1 Server-8286-42A, 2 Server-9080-MHE and 2 Server-9117-MMA. As a result, for all Server-8286-42A and Server-9080-MHE system works fine. Both Server-9117-MMA are not updated.
Every cycle I get in the load_hmc_rest_api.out:
Rest API 2019-03-06 12:40:03 : No /home/lpar2rrd/lpar2rrd/data/Server-9117-MMA-SNXXXXXXX/vhmc01/CONFIG.json, creating..
Rest API 2019-03-06 12:40:03 : Create config jsons in tmp
And in the error.log-hmc_rest_api:
Not a HASH reference at /home/lpar2rrd/lpar2rrd/bin/hmc_rest_api.pl line 856.
