Storage Devices Discovery - Quick and Crisp

[Rahul Priyadars]

Hi All

Just Publishing this quick and crisp article for Storage devices which uses CIM credentials for discovery.

1. The Shazzam probe launches the wbem port probe as part of network discovery.
2. The wbem port probe detects activity on target ports SLP 427, CIM 5989 and 5988, and then examines the Service Registry Queries related list, at Discovery Definition > Port Probes, for the SLP query. The base system provides this query to detect the service:wbem service type, which indicates the presence of an SLP server.

(1) Port Details for Opening

Service Now Instance ----------Mid Server IP ------5988 5989 427 ----------- Storage Infra

(2) Create a CIM credentials 

(2) Run a Quick Discovery for a Given IP 

(3) Discovery Output

 Discovered CIs.

 Once Discovery is done IP will be added into Affinity list of the CIM credentials.

Hi @Rahul Priyadars 

iam discovering Huwaie Sotrage devices for my client will this steps work for me ? or do i need SIM-S agent installation. 

Please guide what is required for Huwaie Storage devices ? URGENT !!!

[Rahul Priyadars]

You can try this way else SMI - S u need to use . Also assuming Huwaie Storage devices are SMI-S Compliant.

--> Discovery queries SMI-S compliant storage devices using CIMIQL queries.

I have few question >

1. yes for SIMs, what the process ? 

2. what should i request the storage team here ?  

3. can i use my existing mid server for SIMs installation ?

4. Were is this sims getting installed on (is it on a new VM), If its a new VM then whats the connectivity with this new vm and mid server and  the storage ? 

5. if sims is used what Will be the source and destionation IP for port opening request ? (currently its MIDServer ip and Storage devices ip, Any change in it as sims will act as an connector inbetween ?)

Please answer ! Iam struck... @Rahul Priyadars .

Conceptual Details Are here

https://docs.servicenow.com/bundle/vancouver-it-operations-management/page/product/discovery/referen...

1. yes for SIMs, what the process ? -In Above URL

2. what should i request the storage team here ?  They will Configure SMI-S Servers

3. can i use my existing mid server for SIMs installation ?- Yes considering VLAN of Mid S and SMI S server is same for communication

4. Were is this sims getting installed on (is it on a new VM), If its a new VM then whats the connectivity with this new vm and mid server and  the storage ? ---> Refer Architecture Diagram in above URL

5. if sims is used what Will be the source and destionation IP for port opening request ? (currently its MIDServer ip and Storage devices ip, Any change in it as sims will act as an connector inbetween ?)---> Conceptually its in Arch Diagram.

Hello Rahul,

Can we go with same CIM set up to discover EMC XTREMIO X02, PowerStore 7000T , VNXe3200 ?

[Rahul Priyadars]

EMC XTREMIO X02- Discovery uses REST APis for Data Collection Details are below.

mhttps://docs.servicenow.com/bundle/vancouver-it-operations-management/page/product/service-mapping/r...

So same CIM cred will not work.

For Other 2 models/Makes please refer below Kb-  

Does Discovery support my Storage Device?

Creds got used,i can see it in ip affinity

PORT 427 and 5988 are open as per ECC queue logs...

Sims is installed and able to find devices from sims server (linux).  and when i run discovery i get the above error. 

@Rahul Priyadars  help !

[mrudula gunturu]

so will the devices get the serial number thought the query  form the probes. Does the serial number actually discovered for the storage devices ?
