I'm coming a little late to the agentless management solution with Gen8 machines. I need to ask a question to understand what changes I may need to make on our blade enclosures.
So, a few things are known to me from managing SIM and the current documentation:
- Best to discover OA's first, which then find iLOs and hosts within the enclosures
- Some type of authentication is required to the OAs, iLOs, and hosts
So, here's what I need to know to successfully manage/monitor enclosures in SIM 7.3+ (with IRS 7+):
- Does every iLO still require a configured user? I assume OA discovery is just that, the OA is not used to talk to iLOs later, it's just to help discover them. After discovery, iLOs will communicate with SIM/IRS directly.
- What does the OA user need as for permissions? I assume it can be a User role, but do I need to grant it access to all bays or is just adding the user for SIM sufficient?
- How do i know what credentials are used for what things? I want to be able to use IRS with the OAs just like the iLOs. I assume this is mainly where SNMP comes in (and the registration process). What about the local OA/iLO user?
I usually do discoveries with SNMP and it works just fine. I'm assuming the user piece is for agentless/IRS as it requires more access. I admit to being a little confused on this. Does anyone have this set up (SIM and IRS) for C7000's and Gen7/8 machines? How did you do it?
It's difficult to correlate all the manuals to figure out the absolute answers on these.. my head is spinning a bit. I have been doing SNMP for a long time, with IRSA, so IRS and agentless changes things a bit, but I still want SIM for internal events.
Thanks..
