Re: [xcat-user] Genesis boot for ppc64le and RAID options for IBM AC922?

[Yuan Y Bai]

Hi Keith,
 
1. ppc64le for POWER9 nodes :  mknb ppc64
 
2. We do not have P9 with hard RAID nodes, we use iprconfig, diskdiscover and configraid in P8 before. You can use iprconfig to check if there are raid devices. You can use iprconfig interactive mode to show devices, or "iprconfig -c show-config". xCAT hard RAID solution is here: https://xcat-docs.readthedocs.io/en/latest/advanced/raid/hardware_raid.html?highlight=configraid
 
3. soft raid in xcat provision : https://xcat-docs.readthedocs.io/en/latest/guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/raid_cfg.html?highlight=raid
 
I think all these should be general for P8 and P9, if you have problem, you can paste here, we can have a look at it together.

Hi All,
 
Two questions regarding the new POWER9 servers (in this case, AC922) and provisioning ppc64le:
 
1.) From documentation and mknb, it appears that creating a working ppc64le for POWER9 nodes is not yet supported. Does anyone know a workaround, or know when this feature might be released? 
 
2.) Also, has anyone used iprconfig, diskdiscover and configraid to discover/configure hardware RAID on Power9? From what I can tell, no RAID solution was configured for the nodes, so the 2 disks appear to be un-RAIDed (show up as 2 distinct devices). 
 
There does not seem to be anything in Petitboot, or similar at boot time, that looks like a RAID configurator (like the Intel RAID one would see on e.g. a Supermicro x86 machine). Have folks used hardware RAID on POWER9 machines, or have they used some software RAID solution, in conjunction with xCAT deployment?
 
Many Thanks,
   Keith--

Re: [xcat-user] Using online repos with xCAT

[Kevin Keane]

I was actually going to ask the same question Keith was asking.

I think Keith wasn't asking about the xcat repositories, but about the
operating system repositories (the ones that are ordinarily created by the
copycds command).

Re: [xcat-user] Using online repos with xCAT

[Casandra H Qiu]

yes, you can use online repo.

In the http://xcat.org/download.html,  there are links to xcat repo file.
https://xcat.org/files/xcat/repos/yum/2.14/xcat-core/xcat-core.repo


Here is another example:

# cat xcat-core.repo
[xcat-core]
name=xcat-core
baseurl=http://xcat.org/files/xcat/repos/yum/devel/core-snap
enabled=1
gpgcheck=0

Hello All,

The references I see to creating repos (base, or updates) on the xCAT
management node all indicate that only local repos are supported (e.g.
"baseurl=file:///..").

Is there any way to use actual online repos with xCAT? If not, how can one
sensibly update the OS on a regular basis? (seems that "reposync" can be
used and just dump the latest update RPMs to a specific directory, then
update that repo?)

BTW: I am using RHEL7. Also, I am using an x86 management node with ppc64le
compute nodes, and xcat 2.14.2.

Thanks,

[xcat-user] nfs mounting root image from different server

[Jeff Berry]

Good afternoon all,

we'd like to mount our statelite root images from a different machine than our 
XCAT master.   Are there any XCAT specific pitfalls I should be aware of and/or 
best practices I should try to follow?

I had hoped it would be as simple as adding an nfsserver entry to the noderes 
table and adjusting the rootimg dir in the osimage object.  However, that 
didn't work out very smoothly.  When I change the rootimgdir, I can no longer 
run liteimg since it looks for that image directory.   When I try just changing 
the root image mount in the tftp file as a test, my node hangs when attempting 
to mount the root image.

That latter problem may be nfs related and have nothing to do with xcat per se, 
but it seems like there must be a way to build/modify the image on the server, 
copy the image to another server, and then do the mount directly from there.  
However, I could be wrong on this ...

lsxcatd -v
Version 2.14.2 (git commit f2090565b1d1b8efa7558d034de0478456c38e4c, built Wed 
Jul 11 07:15:53 EDT 2018)

Anyone tried to do something like this before?

Jeff Berry, MRC CBSU
