The command i'm trying to execute through the CLIRUNNER provided by the RESTAPI is :

$ viosvrcmd -m FRAME --id 1 -c "rmdev -dev XXXXX"

If i execute the command from the HMC CLI, it works.

Is it a bug of the REST API ?

Hi,

Is this an intermittent issue you are seeing while perform REST request? We might get this issue when the underlying commands take longer time to respond. There is a fix available in the 820 SP2 version of HMC. Please update the HMC with the latest service pack. Or Rebooting the HMC should solve the problem. Thanks!

i confirm the issue no longer appear after a reboot.

I'm very disappointed about the stability of HMC software.

This is not the first time i need to reboot an HMC in order to solve an issue.

Hi. I can understand your disappointment. REST API is the newer functionality that is delivered in the HMC. We are working on fixing any resiliency and performance issue we observe in the REST functionality and providing fix as part of the service packs. This is an issue, where the underlying command taking longer time in responding the HMC's interface name/IP. This issue has been fixed by putting the retry and using other mechanism to get the interface name. And the fix is made available in the latest service packs. Please let me know any other issue you see. And also let me know for other issues where you had to reboot the HMC. Thanks!
