This webinar introduces various concepts and features related to disk lease, node expel, and node recovery. It explains the mechanism of disk lease, the common scenarios and causes for node expel, and different phases of node recovery. It also explains DMS (Deadman Switch) timer which could trigger kernel panic as a result of lease expiry and hang I/O. This webinar also talks about best practice tuning, recent improvements to mitigate node expels and RAS improvements for expel debug data collection. Recent critical defects about node expel will also be discussed in this webinar.</font><p><p><b><i><font face="Arial">Please note that our webinars are free of charge and will be held online via WebEx.</font></i></b><p><b><font size="4" face="Arial">Agenda:</font></b><font size="4" face="Arial"> </font><ul><br><font face="Symbol">· </font><font face="Arial">Disk lease concept and mechanism</font><p><font face="Symbol">· </font><font color="#2F2F2F" face="Helvetica Neue">Node expel concept, causes and use cases</font><p><font face="Symbol">· </font><font face="Arial">Node recover concept and explanation</font><p><font face="Symbol">· </font><font face="Arial">Parameter explanation and tuning</font><p><font face="Symbol">· </font><font face="Arial">Recent improvement and critical issues</font><p><font face="Symbol">· </font><font face="Arial">Q&A</font></ul><br><b><font size="4" face="Arial">NA/EU Session</font></b><br><font face="Arial">Date: June 6, 2018</font><br><font face="Arial">Time: 10 AM – 11AM EDT (2 PM – 3PM GMT)</font><br><font face="Arial">Registration: </font><a href="https://ibm.biz/BdZLgY"><u><font color="#0000FF" face="Arial">https://ibm.biz/BdZLgY</font></u></a><br><font face="Arial">Audience: Spectrum Scale Administrators</font><br><br><b><font size="4" face="Arial">AP/JP Session</font></b><br><font face="Arial">Date: June 6, 2018</font><br><font face="Arial">Time: 10 AM – 11 AM Beijing Time (11 AM – 12 AM Tokyo Time)</font><br><font face="Arial">Registration: </font><a href="https://ibm.biz/BdZLgi"><u><font color="#0000FF" face="Arial">https://ibm.biz/BdZLgi</font></u></a><br><font face="Arial">Audience: Spectrum Scale Administrators</font><br>
