If so i assume that remotecluster commands and ping to/from remote cluster are going via the Daemon network ?<br></p><p>Note:<br></p><p>I am aware and read <a href="https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/General%20Parallel%20File%20System%20(GPFS)/page/GPFS%20Network%20Communication%20Overview">https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/General%20Parallel%20File%20System%20(GPFS)/page/GPFS%20Network%20Communication%20Overview</a><br></p><div class="io-ox-signature"><p><span style="font-size: 10pt;">-- </span><br><span style="font-size: 10pt;">Unix Systems Engineer </span><br><span style="font-size: 10pt;">--------------------------------------------------</span><br><span style="font-size: 10pt;">MetaModul GmbH</span><br><span style="font-size: 10pt;">Süderstr. 12</span><br><span style="font-size: 10pt;">25336 Elmshorn</span><br><span style="font-size: 10pt;">HRB: 11873 PI</span><br><span style="font-size: 10pt;">UstID: DE213701983</span><br><span style="font-size: 10pt;">Mobil: + 49 177 4393994</span><br><span style="font-size: 10pt;">Mail: <a href="mailto:service@metamodul.com">service@metamodul.com</a></span></p></div></body></html>
