I tried to reboot server over IPMI and the integrated service processor/BMC. It worked for IBM server with an Integrated Management Module (IMM), but failed with HP iLO2 (FW v2.05).
ipmiutil.exe for Windows so far and would be able to use
ipmitoolon a Linux machine.
Following line worked for an IBM IMM/BMC (shut down server):
ipmiutil reset -d -N 192.168.1.123 -U adminaccount -P adminpassword
Using this for a HP iLO2 I get:
ipmilan_open_session error, rv = -15 ireset: powering down ... set_boot_options ccode 80, resp = c2, resp = e4 ireset: IPMI_Reset error 128 ipmiutil reset, Invalid Session Handle or Empty Buffer
Any hints? Somebody tried this before?
