X6800 can't load ISO through KVM
1. check if the ISO file name include Chinese and path is too long
2. Check if there are other servers face the same issue, and exclude JAVA version and setting
3. telnet BMC ip 8082, check if KVM remote port been blocked
4. Login BMC, BMC part function not correct, suspect BMC process hang, execute bellow command to reset BMC process,problem solved.
ipmcset -d reset
Can't find the root cause, exclude other reasons when do trouble shooting, then suspect BMC process hang issue.
But this issue can't reappear.
