White Paper

Booting from the cluster using /etc/bootptab

All bootptab entries must be maintained on the active cluster node, as this copy is linked to the

shared version /etc/opt/ignite/bootptab. The local copies of /etc/bootptab on the

inactive cluster nodes must not contain entries for clients that will be booting from the Ignite server.

Edit scripts on all cluster nodes for NFS client mounts

The /etc/dfs/dfstab file is not used in this configuration; the Serviceguard control scripts will

export all file systems. Edit all cluster nodes’ control scripts to include NFS exports for recovery

clients. In our case, /etc/cmcluster/ha-iux/hanfs.sh (from the NFS toolkit template) has

the following:

# NFS: Specifies all exported NFS directories with share options. The

# directories must be defined in the mounted file system FS list

specified

# in the control script. These variables are used by the command

"share"

# to share the file systems and the command "unshare" to unshare the

file systems.

# Example: XFS[0]="-o ro /pkg1"

# Example: XFS[1]="/pkg2"

#XFS[0]=""

XFS[0]="-o anon=2 /var/opt/ignite/data"

XFS[1]="-o anon=2 /var/opt/ignite/clients"

XFS[2]="-o

sec=sys,anon=2,rw=sgiux3.fc.hp.com:sgiux4.fc.hp.com:sgiux5.fc.hp.com:

sgiux6.fc.hp.com /var/opt/ignite/recovery/archives"

When using the Ignite UI or commands, always use the virtual server

hostname and IP for the package

If you don't, you will have problems when running on other nodes, since Ignite stores the server IP

in its config files.

Managing recovery images for cluster nodes

Recovery images for the individual cluster nodes can be created and restored as well, providing at

least one cluster node remains running throughout the process. Always do this for nodes that are

inactive. For example, if a package is running on node1, you can run make_net_recovery on

node2 and also re-ignite node2 from the cluster itself. Again, always use the virtual server

hostname and IP address.
