9. The server pings the client with an ICMP type 8 echo request. The client answers the ping with

an ICMP type 0 echo reply. If tftp is enabled, the version check is done with the file /opt/

ignite/data/Version.

10. If tftp is not enabled, the version check is done with swlist using the swinstall depot

sequence described in Figure 28 (page 86).

11. If the client has a lower version of Ignite than the server, a depot of recovery commands is

transferred to the client using the swinstall depot sequence described in Figure 28

(page 86).

NOTE: Although swinstall is illustrated here, the install could use one or more of

swinstall with remsh (port 514), NFS (ports 49152–65535), ftp data (port 20), and

ftp (port 21).
