Recommended approach for Storage Discovery Credentials

sujanmattaparth · ‎09-02-2020

Hi,

I see that in the below article it is mentioned that to use CIM Server for Storage Discovery. But it is not very clear in the documentation. Can you please help me with the below question?

What is the recommended approach for Storage Discovery for Netapp, EMC, Brocade Storages? Can we just go with configuring SNMP Community String and Rest API ServiceAccount where applicable and use CIM for Brocade Storage? (Orlando & Paris)

Hi,

I will share what we did recently:

1) For NetApp storage devices: We used SNMP and Basic auth credentials to discover this devices using NetApp patterns.

2) For discovering the EMC storage, IBM, etc we are doing CIM and SMI discovery. Where we have to open few ports on the MID server and between the Server which host the SMI agent and the storage server.

3) We also did some custom probe development for getting some other details.

Please let me know if you face any issue in getting this to work.

Thanks,
Ashutosh

Thank you so much. Do you know what type of data we can't get while using the SNMP Community String when compared to CIM/SMI-S? I am planning to compare OOB fields from the documentation anyways but want to validate.

HI,

That i am not aware of in detail. but the data which is discovered is on Docs for NetApp and for Storage via CIM.

We get most of the important data though.

Thanks,

Hi Ashutosh,

For Netapp storage devices, did you use Cyberark basic auth credential or local basic auth credential?

If you are using Cyberark, did you face any issues in discovering Netapp devices?

Hi,

CyberArk. NO issues.

Thanks,

Hi Ashutosh,

When you say we need SNMP and basic auth credentials, can you please give more details on what basicauth credentials are needed on the NetApp storage system? I have created SNMPv3 user on the NetApp system as well as create another user with read-only http and ontapi permissions, however it doesn't seem to work yet.

Kind regards,

Au
