Basic instruction for Serviceguard for Linux.
These instruction are pulled from a basic "hands on" class & with some double checks of the manuals should get you started.
First I assume that both servers are listed in the certification matrix:
ftp://ftp.compaq.com/pub/products/servers/ha/linux/svcguard-certmatrix.pdfMake sure you have set up NIC bonding as described in the "managing" manual.
http://docs.hp.com/en/B9903-90050/B9903-90050.pdfMake sure multipath is configured to storage (check the docs of the HP version of the FC driver.
Start with the release notes:
http://docs.hp.com/en/B9903-90051/B9903-90051.pdfPages 23-28 (most summarized below)
Define a LockLUN on the MSA1000 (just look up lock lun in the managing manual.
Make sure you set up the
OS Settings (when installing)
├в ┬в Allow SSH
├в ┬в Custom package selection
├в Add ├в Development tools├в
├в ┬в Required for the installation of ├в Deadman├в and ├в Pidentd├в drivers
├в ┬в These drivers need to be rebuilt with any kernel update
├в Instructions are in release notes
├в Other packages may be required for your environment
├в ┬в Network bonding
├в Use standard network bonding
├в ┬в Multipath
├в QLogic or Emulex built in multipath in the HP versions of the drivers
├в ┬в Firewall
├в Turn off for now
Install Serviceguard rpms +
├в ┬в Do the following on node1 and node2
├в ┬в Remove authd in preparation for pidentd install
├в # rpm -e authd
├в `Pidentd replaces (can├в t get RedHat to fix authd)
├в ┬в Install SGLX rpms
├в # rpm ├в ihv sgcmom*.rpm pidentd*.rpm serviceguard*.rpm
├в ┬в Start pidentd and set it to start automatically at boot
├в # /sbin/chkconfig --level 35 identd on (double dash on level)
├в # /etc/init.d/identd start
Set up profile & man pages
├в ┬в Edit cmcluster.conf.default so run at boot
$SGCONF = /usr/local/cmcluster/conf
├в Copy $SGCONF/cmcluster.conf.default to /etc/profile.d as BOTH sglx.sh.
├в Edit the files to add
export PATH=${PATH}:/usr/local/cmcluster/bin or
├в # chmod +x /etc/profile.d/sglx.*
├в # source /etc/profile.d/sglx.*
├в ┬в Make sure $SGCONF/cmclnodelist exists and is correct (├в + +├в without the quotes works for all)
├в ┬в Edit the /etc/man.config file to include the following line:
├в MANPATH /usr/local/cmcluster/doc/man
SGLX Initial Security Settings
├в ┬в Deal with SG-LX security
├в ┬в See docs for higher security
├в ┬в Edit /etc/hosts (all nodes)
├в ┬в Reboot the nodes
├в While not an absolute requirement, helps catch some problems
Create a cluster
├в ┬в # cd $SGCONF
├в ┬в # cmquerycl ├в v ├в w full ├в L locklun -n node1 ├в n node2 ├в C mycluster.conf
├в -w full option does much more checking
├в ┬в Edit mycluster.conf
├в Generally you├в ll want to change the cluster name in the file.
├в change the max number of packages ├в 10 is a good starting point.
├в Set the security at the end of the file. An easy setting is:
├в ┬в USER_NAME root
├в ┬в USER_HOST ANY_SERVICEGUARD_NODE
├в ┬в USER_ROLE FULL_ADMIN
├в ┬в # cmapplyconf -v ├в C mycluster.conf
Test the cluster
├в ┬в # cmruncl ├в v
├в ┬в # cmviewcl ├в v
├в Make sure that the quorum status (LockLUN or QS) is OK as well as the servers
├в ┬в Reboot the node1 and make sure that node2 stays active.
├в ┬в Once it has competed the reboot add it back in and again check the status
├в # cmviewcl ├в v
├в ┬в reboot the node2 and make sure that node1 stays active.
├в ┬в Once it has competed the reboot add it back in and again check the status
├в # cmviewcl ├в v
