I was able to get this CLI from Nimble support - thanks Nimble for being so responsive!
Nimble OS $ auditlog --list
This will give you all records in the audit log. btw, the audit log only contains records from your last controller switch, so in my case, 222 days.
Active controller: B State: active Peer controller: A State: standby
Active controller uptime: 14:51:24 up 222 days
Is there anywhere in logs, analytics or InfoSight that I can show Oracle that no other volumes ever connected to a specific initiator? ACL log? A Nimble ACL in regards to Initiator groups shows who is connected now but is there a history log somewhere? CLI?
