Workspace Db2 Analytics Accelerator for z/OS

RELATED IDEAS

Db2 Analytics Accelerator should be catching up changes dynamically on status of HW resources(NVME,OSA,ROCE,Ficon) over LinuxONE when resource come back online after toggle operation.

For LinuxONE systems, MCL or failure of some HW parts sometimes leads us to toggle operation to be able to fix or enable HW resources. What we have noticed is when HW resources (NVME,OSA,ROCE,Ficon) toggled offline over LinuxONE, Db2 Analytics Accelerator marks it as red over Admin UI. But sadly after change is performed if we want to toggle that resource back online Admin UI doesn't show it as available and requires deactivation/activation of all Accelerators which are using that affected resource. Unfortunately that means each time service needs to go down and start back again. When considering for production environment with lots of resources(CPU,memory,..) that task takes some time for system to finish. Addition to that requires someone to perform deact/act over HMC

What we used to have on z systems is, this kind of small toggle actions can be handled dynamically without any affect or any additional actions to take. With some zOS commands we have a possibility to manage change and eliminate any potential affects of toggle operation. I am aware SSC is different running environment than z/OS lpars but somehow if we have this feature on new versions that would relieve us from burden of deactivation/activation of each accelerator even for the small operation.
