Hi Jarrod,
Thanks for your comments,
You know, we don't *need* Legacy only in xCAT 2.7 anymore for
RHEL6, SLES11, Win2k8, and ESXi5. Older versions of each would
need Legacy only though.
That was my suggestion there in the first comment, and in-fact you
don't need it, and I only realised it later in the day when I
couldn't get nodes discovered in the legacy modes, and was able to
via the uEFI method. I was very impressed. (I solved my problem in
the end though ("spanning-tree edge" on switches))
Other than that, looks reasonable enough. The performance and
efficiency impact of the settings vary by workload of course, so
the 'your mileage may vary' is very true.
I only mimicked the config that was already in the templates, so
that is what I put up.
The exception would be HS23 servers. There you'd also want to
put Legacy serial data out COM2 instead of COM1. For all the
rackmount/iDataplex and Flex servers, COM1 default is good.
Cool, no problem; I was going to commit this, and symbolic link to
the MT of the new dx360 M4, not sure if it would be useful to add it
into the templates
On another 2 other notes,
1.
I did find an issue with genesis with compression with lzma. when
doing mknb x86_64, it was creating the image correctly, but the
corresponding files in /tftpboot/xcat/xnba/nets, still had the .gz
extension of the genesis.fs, rather than lzma. I will be debugging
this further tomorrow, and see if I can generate a patch to fix
this.
2.
When there is no mac address allocated in the mac table for a node,
and you ask to do an operation such as nodeset which includes other
nodes as well, it will not allow you to install the other nodes, and
fail due the specific node not having a mac address. i.e. if I have
node001-node050, and for some reason was not able to discover
node037, but I wanted to install all the nodes. When doing so in the
fashion "nodeset node001-node050", this will end up failing. I don't
remember being the case previously. I will get more info on this if
required

IBM M4 nodes
All,
For anyone installing M4 nodes, below is the corresponding ASU
settings that I have used that are similar to the hpc/sol
settings in
/opt/xcat/share/templates. It could be that we no longer require
the
BootOrder definition, as the uEFI PXE boot should now work. This
has
worked for me, any ideas from anyone that would go a bit further
in
terms of configuration.
loaddefault uEFI
loaddefault BootOrder
set BootOrder.BootOrder "Legacy _Only_=PXE Network=Hard Disk 0"
set Processors.Hyper-Threading Disable
set DevicesandIOPorts.RemoteConsole Enable
set DevicesandIOPorts.SerialPortSharing Enable
set DevicesandIOPorts.SerialPortAccessMode Dedicated
set DevicesandIOPorts.Com1TerminalEmulation VT100
set DevicesandIOPorts.Com1ActiveAfterBoot Enable
set DevicesandIOPorts.Com1FlowControl Hardware
set OperatingModes.ChooseOperatingMode "Custom Mode"
set Processors.C1EnhancedMode "Disable"
set Processors.TurboMode "Enable"
set Processors.PackageACPIC-StateLimit "ACPI C3"
set Processors.QPILinkFrequency "Max Performance"
