One of the major new features in FreeIPMI 0.4.1 is hostrange support. It is covered in far more detail in this doc:
http://www.gnu.org/software/freeipmi/freeipmi-hostrange.txt However, I thought I'd give a bit of an introduction on this mailing list for the people unfamiliar with other tools that offer similar functionality. Starting with FreeIPMI 0.4.0 hostrange support has been added into ipmi-chassis, ipmi-fru, ipmi-raw, ipmi-sensors, ipmi-sel, bmc-info, and ipmimonitoring (it has existed in ipmipower since 0.1.0). Hostrange support gives you the ability to specify multiple hosts for an ipmi command have that command executed across multiple hosts, out-of- band, in parallel. This can greatly decrease the time it would otherwise take to execute them in serial via a shell script. This can save large amounts of time when executed across a large cluster. Several options exist that will enable you to buffer or consolidate the information to make it easier to read as well. As an example, the below runs bmc-info across a small 6 node cluster. The output clearly shows that the firmware is not consistent across each node of the cluster below. # > bmc-info -h "pwopr[0-5]" -u XXX -p XXX -C ---------------- pwopr[0-1,5] ---------------- Device ID: 22 Device Revision: 1 Firmware Revision: 1.12 [Device Available (normal operation)] IPMI Version: 2.0 Additional Device Support: [Sensor Device] [SDR Repository Device] [SEL Device] [FRU Inventory Device] [Chassis Device] Manufacturer ID: 28C5h Product ID: 4h Aux Firmware Revision Info: 38420000h Channel Information: Channel No: 1 Medium Type: 802.3 LAN Protocol Type: IPMB-1.0 Channel No: 5 Medium Type: Asynch.
