I am an ipmitool newbie. My questions must be FAQs, but I was unable to locate the answers.
Dell PowerEdge 850 running BMC version 1.52 ... the latest firmware. playing around with basic 'power chassis' commands (status, on, off, soft, reset) across the 'lan' interface. I observe that after sending a command that changes the power status (on, off, reset) the BMC controller does not respond for a while. I send the following sequence: $ ipmitool -I lan -H pe850a-ipmi -U root -P pw chassis power off Chassis Power Control: Down/Off $ ipmitool -I lan -H pe850a-ipmi -U root -P pw chassis power status Error: Unable to establish LAN session ipmi_lan_send_cmd failed to open intf Unable to get Chassis Power Status $ ipmitool -I lan -H pe850a-ipmi -U root -P pw chassis power status Chassis Power is off If I power on or reset the same thing happens ... BMC does not respond for approx 15 seconds after a power change. Q: Is it normal for BMC to not be available, including checking status) for some period of time after a power transition? Q: Is there a specification that defines how long this period of time should be? Q: If not, what kinds of times are typical? Q: Does it vary from implementation to implementation? I wrote a command line and that asked for 'power chassis status' and slept for 2 seconds. I observe that there are times during OS driver initialization when it times out. Presumably this happens because the driver is interfering with the NIC and blocking BMC access. Q: What are 'typical' times for this blockage when the NIC driver initializes?
