The Kickstart file used to install this node.
•
The /mnt mount-points for the Lustre file system.
Many of these files are available from other server nodes in the cluster, or from the failover
pair node in the case of the Heartbeat configuration files. Other files may be re-created
automatically by Kickstart.
3.
Upgrade the server according to the general installation instructions in
with specific instructions for this upgrade.
4.
Reboot as necessary.
5.
If applicable, restore the files saved in step 2.
Please note that some files should not be restored in their entirety. Only the HP SFS specific
parts of the older files should be restored. For example:
•
/etc/fstab
— Only the HP SFS mount lines
•
/etc/modprobe.conf
— Only the SFS added lines, for example:
# start lustre config
# Lustre module options added automatically by lc_modprobe
options lnet networks=o2ib0
# end lustre config
6.
For the upgrade from SFS G3.0-0 to SFS G3.1-0, you must re-create the Heartbeat configuration
files to account for licensing. For the details, see
.
7.
Verify that the system is properly configured. For example:
•
/var/lib/heartbeat/crm/cib.xml
— Verify the owner is hacluster and the group
is haclient as described in
•
/etc/ha.d/authkeys
— Verify permission is 600 as described in
•
/var/lib/multipath/bindings
— Run the multipath -F and multipath -v0
commands to re-create the multipath configuration.
•
Verify the Lustre file system mount-points are re-created manually.
•
Bring any Ethernet or InfiniBand interfaces back up by restoring the respective ifcfg
file, and using ifup, if required.
8.
Restart the Heartbeat service.
# service heartbeat start
# chkconfig heartbeat on
Lustre components that are served primarily by this node are restored to this node.
9.
Generate new Heartbeat files for G3.1-0 using the instructions in
