Jorg, the notes I have for setting up Intel BMCs are not of any use to you, sorry. See below.
Regarding the PXE booting, t is easy to use the syscfg utility to print out and to set the boot order. But I do not think this is your problem. https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/Intel_Syscfg_UserGuide_V1.02.pdf The IPMI interfaces have three LAN Channels – 1, 2, 3 LAN Channel 3 is the one used by the AXXRMM4LITE add-on management module http://ark.intel.com/products/55168/Remote-Management-Module-AXXRMM4LITE To configure LAN channel 3: *module load ipmitool * *ipmitool lan print 1* (to show the configuration of Channel 1) *ipmitool lan set 3 ipaddr 172.16.202.XXX * (to set the IP address the same as Channel 1) *ipmitool lan set 3 netmask 255.255.255.0* *ipmitool lan print 1* (to show the configuration of Channel 1) The Bright Cluster manager uses user number 4 to access the IPMI interface. This user is named ‘bright’. You should set the level of access for user 4 on LAN Channel 3: *module load ipmitool ; ipmitool user priv 4 0x4 3* *module load ipmitool ; ipmitool channel setaccess 3 4 callin=on ipmi=on link=on privilege=4* *ipmitool channel getaccess 3 4* On 21 June 2018 at 12:25, Jörg Saßmannshausen <sassy-w...@sassy.formativ.net > wrote: > Hi John, > > thanks for the reply.
