HP Serviceguard Toolkit for NFS Version A.03.03.01 on Linux User Guide (December, 2012)

Mounting NFS shares at client node
Using the package name in the mount command, you must NFS-mount a file system on the client
system. The package name is associated with the relocatable IP address of the package. On the
client systems, you must use a hard mount. For auto-mounter, the timeout must be greater than the
total end-to-end recovery time for the Serviceguard NFS package, which includes failover time,
running fsck, mounting file systems, and exporting file systems on the new node. The default
value of the timeout is five minutes. If you set the timeout to zero, it does not allow you to unmount.
Rolling Upgrade
Toolkit package nodes in a cluster can be upgraded with the new toolkit, on one node at a time
as follows:
1. Backup the package directory and package control scripts if any.
2. Move the running NFS toolkit packages off the node being upgraded to another package
node.
3. Upgrade the NFS toolkit using the following command:
rpm -Uvh --noscripts
serviceguard-nfs-toolkit<version_number>.<OS_distro>.noarch.rpm
4. Verify the installation, using the following command:
# rpm -q serviceguard-nfs-toolkit
serviceguard-nfs-toolkit-<version number>
NOTE: At this point packages can be migrated back to the current node.
5. Repeat the above steps on all the other toolkit package nodes in the cluster.
NOTE: For rolling upgrade of HP Serviceguard Toolkit for NFS on SLES11 from older version of
toolkit to current toolkit version, lock_migration.sh script must be available in the newly
upgraded node. Before you start the older version of HP Serviceguard Toolkit for NFS on Linux
package on the newly upgraded node, you must copy the lock_migration.sh script from non
upgraded node to all the other packaged nodes where new version of toolkit is installed. This is
applicable only for the packages created on SLES 11 OS. For example, to copy the
lock_migration.sh script from the host node1 to host node2, run the following command from
host thyme:
# scp -p $SGCONF/scripts/tkit/nfs/lock_migration.sh
root@node2:$SGCONF/scripts/tkit/nfs/
