#This plugin enables stateless boot of IBM Bootable Media Creator as
|
|
#a provisioning target.
|
|
#Instead of 'genimage', the first step here is to visit IBM support website
|
|
#and download the bootable media creator utility
|
|
#Download the version intended to run on your management node, regardless of
|
|
#the managed node platform. I.e. if your management node is RHEL5 and your
|
|
#managed nodes are SLES10, an example download would be:
|
|
#https://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5079820&brandind=5000008
|
|
#Then, execute the utility. Mostly choose preferred options, but you must:
|
|
#-Use '--tui' (this instructs ToolsCenter to evoke the text startup path that xCAT coopts
|
|
#-Use --pxe /instal/netboot/bomc/x86_64/compute (x86_64 may be x86 and compute may be whatever profile name is preferable).
|
|
#-m should be given a list of 'machine type' numbers. If the nodes underwent
|
|
#the xCAT discovery process, this can be extracted from the vpd.mtm property:
|
|
#$ nodels n3 vpd.mtm
|
|
#n3: 7321
|
|
#It should then be possible to run 'nodeset <noderange> netboot=bomc-x86_64-compute'
|
|
#Future ToolsCenter enhancements may dictate that we drop support for version 1.10 to cleanly take advantage of it
