Hello Community,

 

I'v install NetApp SLM Version 1.0RC4 Build: 1712060548

 

I'm trying to add single node cluster ontap storage systems.

But it failed to get Capability

If i try to get Capability by CLI with ontap-performance-sizer.sh

It end with the following error:

Do you know if this is a know issue with single node cluster ontap storage system?

 

TIA

NSLM does not support Single node cluster, The support is for HA pair.This is the reason the discovery is failing.

Hi pmunshi,

 

Thanks for the clarification

But do we have an explanation of why single node cluster are not supported?

 

TIA
