Aggregate data transfer rate: 6,978.46 KB/sec Objects compressed by: 0% Subfile objects reduced by: 0% Elapsed processing time: 00:02:16 ANS1074W The operation was stopped by the user. 16.6.1 Determining whether the data movement is LAN-free Monitor the administrative CLI query session output against the node that is running the LAN-free backup. Review the bytes sent and bytes received. In out test, Example 16-29, when LAN-free data movement was occurring, a query session on the Storage Agent shows about 683 MBs received so far from the DIOMEDE node, displayed in the Bytes Recvd column. Example 16-29 LAN-free session statistics on Storage Agent tsm: ATLANTIC>sta_diomede: query session ANR1699I Resolved STA_DIOMEDE to 1 server(s) - issuing command QUERY SESSION against server(s). ANR1687I Output for command 'QUERY SESSION ' issued against server STA_DIOMEDE follows: Sess Comm. Sess Wait Bytes Bytes Sess Platform Client Name Number Method State Time Sent Recvd Type 1 Tcp/Ip IdleW 11 S 679 1.9 K Server AIX-RS/6000 ATLANTIC 3 Tcp/Ip IdleW 0 S 3.5 K 253 Server AIX-RS/6000 ATLANTIC 4 Tcp/Ip IdleW 0 S 2.9 K 3.2 K Server AIX-RS/6000 ATLANTIC 7 Tcp/Ip Run 0 S 382 682.7 M Node WinNT DIOMEDE 8 Tcp/Ip Run 0 S 10.2 K 11.0 K Server AIX-RS/6000 ATLANTIC 12 Tcp/Ip Run 0 S 160 234 Admin AIX-RS/6000 ADMIN ANR1688I Output for command 'QUERY SESSION ' issued against server STA_DIOMEDE completed. The output on the Tivoli Storage Manager server shows a very small number of bytes of metadata received for the same node. This confirms that data movement is LAN-free. See Example 16-30.
