Hi Jarrod,
Okay, I upgraded to xCAT 2.7.3 and installed the xCAT-genesis-x86_64 and
elilo-xCAT RPMs and I reran mknb x86_64 to recreate the
/tftpboot/xcat/xnba/nets files and it also reported "Creating
genesis.fs.x86_64.gz in /tftpboot/xcat". But I still get a missing NIC
driver error when I PXE boot (this time explicit - confirming this is the
problem). Upon PXE boot the clients get yaboot first, then load xnba.kpxe,
which according to my /etc/dhcpd.conf file is set up to query the
appropriate nets file:
*if option user-class-identifier = "xNBA" and option client-architecture =
00:00 { #x86, xCAT Network Boot Agent*
* always-broadcast on;*
* filename = "http://10.20.0.1/tftpboot/xcat/xnba/nets/10.20.0.0_16";*
Inside that file is:
*[root@x3650-head01 etc]# cat /tftpboot/xcat/xnba/nets/10.20.0.0_16*
*#!gpxe*
*imgfetch -n kernel http://${next-server}/tftpboot/xcat/genesis.kernel.x86_64
xcatd=10.20.0.1:3001 BOOTIF=01-${netX/machyp}*
*imgfetch -n nbfs http://${next-server}/tftpboot/xcat/genesis.fs.x86_64.gz*
*imgload kernel*
*imgexec kernel*
In my apache log I see:
10.20.253.236 - - [07/Aug/2012:13:36:23 -0500] "GET
/tftpboot/xcat/xnba/nets/10.20.0.0_16 HTTP/1.0" 200 235 "-" "gPXE/0.9.7"
10.20.253.236 - - [07/Aug/2012:13:36:23 -0500] "GET
/tftpboot/xcat/genesis.kernel.x86_64 HTTP/1.0" 200 3942032 "-" "gPXE/0.9.7"
10.20.253.236 - - [07/Aug/2012:13:36:23 -0500] "GET
/tftpboot/xcat/genesis.fs.x86_64.gz HTTP/1.0" 200 20210204 "-" "gPXE/0.9.7"
Then genesis boots and (after I removed 'quiet' from the kernel arguments)
does some initial boot checks and then it goes into a loop of dumping to
the screen the help/syntax screen for grep (which indicates to me that what
it is greping for is failing - possibly /tmp/dhcpserver like before).
Eventually it gives up and prints this to the screen:
"ERROR Unable to find boot device (*maybe* the *nbroot is missing* the *
driver* for your *nic*?)"
At that point it just sits there, and does not try anything else.
What have I done wrong here? Is maybe the BOOTIF argument to genesis kernel
wrong? Also why is it looking for nbroot? There was a previous bootloader
in /opt/xcat/share/xcat/netboot/x86_64/nbroot/ but it should be looking
in /opt/xcat/share/xcat/netboot/genesis/x86_64/ since it is using genesis,
correct?
Any ideas?
