<font size=2 face="sans-serif">Hello Bob,</font><br><br><font size=2 face="sans-serif">4.2.2 is the release were we introduced
"mmhealth cluster show". And you are totally right, it can be
a little fragile at times.</font><br><br><font size=2 face="sans-serif">So a short explanation: </font><br><font size=2 face="sans-serif">We had this situation on test machines
as well. Because of issues with the system not only the mm-commands but
also usual Linux commands </font><br><font size=2 face="sans-serif">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><font size=2 face="sans-serif">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><font size=2 face="sans-serif">know, that it is the CSM and will not
start the corresponding service for that. </font><br><br><br><font size=2 face="sans-serif">If you want me to look further into
it or if you have feedback regarding mmhealth please feel free to send
me an email (Anna.Wagner@de.ibm.com)</font><br><br><font size=1 face="Arial">Mit freundlichen Gren / Kind regards</font><br><br><font size=2 face="Arial"><b>Wagner, Anna Christina</b></font><br><br><font size=1 color=#0060a0 face="Arial">Software Engineer, Spectrum
