Bringing the LPAR resource offline may fail
Bringing the LPAR resource offline may fail with the following message in the engine_A.log file.
<Date Time> VCS WARNING V-16-10011-22003 <system_name>
LPAR:<system_name>:offline:Command failed to run on MC
<hmc_name> with error HSCL0DB4 An Operating System
Shutdown can not be performed because the operating system image
running does not support remote execution of this task from the HMC.
This may be due to problem in communication with
MC <hmc_name>
This is due to RMC failure between HMC and management LPAR. Since the LPAR could not be shutdown gracefully in offline, the LPAR is shutdown forcefully in the clean call, hence it shows as Faulted.
Workaround: In order to recycle the RSCT deamon for LPAR and HMC, refer the Storage Foundation® and High Availability Solutions Virtualization Guide.
