cuz search requests like "Reset BMC via SMASH-CLP Console" led to this page, I think we need a solution here, so if anyone face with such a problem - he could deal with it. I hope so.
problem with BMC web-panel, neither HTTP nor HTTPS is loading properly.
1st solution (if SSH still works):
login to Smash CLP via ssh, and run next few commands:
cd /system1/sp1/enetport1/lanendpt1/ipendpt1 set committed=0 set committed=1
This will reload BMC, so perhaps you'll gain access.
2nd solution (if you have only access to the system running on the server):
first, install IPMI management utilities - ipmiutil. Then run the command below:
ipmitool bmc reset cold
This will restart BMC, without affecting the server itself.
If you have remote access, but first solution for some reason didn't help you - you can use ipmitool with remote host as showed in next command (don't forget to install ipmiutil on client host):
ipmitool -H hostname -U username -P password -v bmc reset cold
You must change the hostname, username and pasword in command to your own.
