Cohesity discovery prerequisites

Community Alums · ‎06-02-2023

Hi Team,

I checked the servicenow documentation and found they have added cohesity operating system pattern in discovery pattern and service mapping plugin . i have upgraded the plugin and i can see in servicenow pattern cohesity pattern got added.

i checked the prerequisite and i am no clear how we can discover cohesity device in ServiceNow. if someone can please help me to provide the prerequisites and steps to perform for cohesity device end and ServiceNow side to discover.

Regards,

RK

SNOW's docs on this are worthless. I even told them while I was working a case I opened with them for this issue.

To start, make sure you are on Cohesity patch 30 for 6.6.0d users or later. There was an issue introduced sometime before that which changed the API path for Cohesity that prevented SNOW from seeing the chassis and node details.

Then you do have to create a serverless discovery, as their doc states (but was only updated after I mentioned it) except they don't list all the specific details.

1) Create a credential alias, type 'credential'

2) Cred is basic auth

3) In the serverless discovery schedule you have to create at least one 'Serverless Execution Pattern'

- Select 'Cohesity Storage System' for the Pattern

4) Create two Discovery Pattern Launcher Parameters

*** I created two of these since they won't work with Cohesity's VIP. I just chose 2 of the IPs contained within the VIP***

- credentialAlias - Value = the alias you previously created
- cluster_ip - Value = one of the IPs within the Cohesity VIP

Hopefully this helps. Lmk if you have any questions.

Hi Jack33,

This issue is from Coherity side and you need to raise Coherity vendor case to update the hotfix for Coherity to discover and parse the variable from pattern in ServiceNow.

Hi Jack33,

Yes, Rakeshkmr below has the correct instructions there.. There is a hotfix that Cohesity has prepped but the problem is it's not available for all versions of Cohesity software. Suffice to say, you need to create a ticket with Cohesity Support and have them apply the hotfix for that, once done, you will then see the appropriate chassis and node info.

One thing of note, however, the Related List tabs are at the moment useless to show nodes and chassis info, if your form view does NOT include Related items section, I encourage you to add that section to your form view then (after having the hot fix applied and clusters re-discovered, you will see the nodes under the relationship views

Thanks for support and added info! Curious, during your talks with SNOW did they mention updating the way it discovers Cohesity? This manual config is a bit ridiculous.

As for your form issue, I never had that problem. The related items section was already there. It is for the majority of our CIs though.

Hi David,

Thanks for your reply.. Yeah I figured out the whole Related Items thing.. so we're good there. and I've pointed out to ServiceNow that the Related Links tabs are worthless..

One question I do have for you though David is with regards to the Basic Auth Credential for this discovery,

Can that credential be domain based and if so, what format must the user name be in? We can't for the life of us get it to work and we've tried several combinations including "Domain@user, user@domain, domain\user, etc..
