I got into this chicken egg scenario: My vCenter certificate was expired. I tried to regenerate the certs by following this VMware Knowledge Base
But the regeneration failed with error "lstool get failed: 1", looks like the Nimble storage plugin is causing the problem. According to this VMware Knowledge Base just remove the plugin, all should be good. But I cannot remove it from vCenter portal as its down due to certificate expiry!
Anyone know a way to remove the plug other than the MOB url suggested in this VMware Knowledge Base ?
