"mmhealth cluster show". And you are totally right, it can be
a little fragile at times.</font><br class=""><br class=""><font size="2" face="sans-serif" class="">So a short explanation: </font><br class=""><font size="2" face="sans-serif" class="">We had this situation on test machines

also usual Linux commands </font><br class=""><font size="2" face="sans-serif" class="">took more than 10 seconds to return.
We have internally a default time out of 10 seconds for cli commands. So
if you had a failover situation, in which the cluster manager </font><br class=""><font size="2" face="sans-serif" class="">was changed (we have our cluster state
manager (CSM) on the cluster manager) and the mmlsmgr command did not return
in 10 seconds the node does not</font><br class=""><font size="2" face="sans-serif" class="">know, that it is the CSM and will not
