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 can use one or more of swinstall with remsh (port 514), NFS (ports 49152–65535), ftp data (port 20), and ftp (port 21).
