Re: [xcat-user] Wrong kernel module getting loaded in stateless image.

Thanks to David Johnson from brown.edu who followed up on my message. I forgot that when I copied over the boot image from cluster 1 to cluster 2 I needed to rerun nodeset, so that the initrd that had the updated bfa.ko in it was copied from /install/netboot and placed into /tftpboot. Thanks aga

[xcat-user] Wrong kernel module getting loaded in stateless image.

Hello, I have 2 iDataplex clusters both running RHEL6.4, based on November 2013 best recipe. Both clusters are using IBM x3650M3 nodes for GPFS servers. The nodes are stateless and boot from an image that is shared between the two clusters. The x3650M3's in both clusters all have Brocade 82

Re: [xcat-user] Changing IP address of existed nodes

Found a solution - ran *nodeset compute boot.* The command recreated the files in /tftpboot/pxelinux.cfg It was important for me NOT to re install the already existed systems, just to change their IP's. Thank you for your great help everyone ! Thank you, Dennis. On Thu, Mar 6, 2014 at 3:42 PM,

Re: [xcat-user] how to recover deleted table rows...

I would hope you are taking regular backups of the database using dumpxCATdb.If you have that backup directory, then you can go to that directory and run tabrestore bootparams.csv . If you have not been taking backups , then this is the reason to setup a cron job to do regular backups and k

Re: [xcat-user] Changing IP address of existed nodes

After I changed the IP addresses of the nodes, it appears as if the clients are searching for a different file in /tftpboot/pxelinux.cfg: This is the current list of the files in /tftpboot/pxelinux.cfg -rw-r--r-- 1 root root 118 Mar 5 18:11 0A0A0A lrwxrwxrwx 1 root root 4 Mar 5 18:37 0A0A0A01 -

Re: [xcat-user] Changing IP address of existed nodes

Hmm, what happens if you 'rsetboot hd'? Do they boot? If that is the case, what server platform are we talking about? It could be a bad interaction between pxelinux and the BIOS of the system... From: Dennis Zheleznyak To: xCAT Users Mailing list Date: 03/06/2014 05:32 AM Subject:

Re: [xcat-user] Changing IP address of existed nodes

Did you follow all these instructions which include running makedhcp -n and makedhcp -a. https://sourceforge.net/apps/mediawiki/xcat/index.php?title=Changing_the_Service_and_compute_nodes_Hostname_and/or_IP#Changing_the_Hosthame.2FIP_address_on_the_Linux_nodes_managed_by_xCAT Is your network tabl

Re: [xcat-user] Changing IP address of existed nodes

Problem fixed - I used GRANT ALL on xcatdb.* TO xcatadmin@'' IDENTIFIED BY '' After completing all the phases I encountered a problem with the nodes - they can't pass the PXE phase to boot from the local disk. I deleted the old /etc/dhcp/dhcp.conf and created a new one with makedhcp -a and renamed

Re: [xcat-user] Service nodes and regenerating their leases on startup

Since xCAT does not know whether the dhcpd (includes the leases file) has been configured, so in each starting of xcatd, the dhcpd is reconfigure with 'makedhcp -n and makedhcp -a". You can try to work around it to set the setupdhcp attribute of service node to '0'. Thanks Best Regards --

Re: [xcat-user] Changing IP address of existed nodes

I encountered a problem when following the article you've provided, Lissa. Running CentOS 6.5 and the latest xCAT version. *I ran the following commands:* tabprune -a auditlog tabprune -a eventlog xcatsnap -d /root/xcat_06.03 lsxcatd -a# Verified that the cluster runs on the old IP. dumpxCATd
