Recommended approach for Storage Discovery Credentials

[sujanmattaparth]

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,

For CIM credentials to manage access to CIM servers like storage device such as NetApp device's in addition SMI-S agent must be installed on the CIM server.

 Windows, Unix or Esx credentials needed to discover host server depending on the type of credentials. Create a new discovery behaviour for may be for NetApp and also create a CIM type of credentials for the "root" user.

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

Hi Ashutosh,

Thank you for your reply. In #3 point you mentioned that you did some custom probe is that because SNMP Community gets fewer details when compared to CIM? Did you observe more info while connecting through CIM Server?

Hi,

SNMP was used yes, using CIM i have seen the OOB data mentioned by servicenow but nothing more. But that is possible if you have SLP queries.

Thanks,
