===== Memory object size of exceedsgranule size - Increase granule size. =====

=== Symptomes ===

After adding additional physical memory (RAM) and changing CLM to ILM on the Npar, the following boot errors occur when trying to start the Vpar Monitor (vpmon):

<code>

\efi\hpux\AUTO ==> boot vpmon -a

Console is on virtual console - via PCDP Current CLM granule countfor cell 0 is 512.
Memory object size (24636) of exceedsgranule size (128). Rebooting the system. Increase granule size.
</code>

=== Causes ===

The ILM granule size, which is currently set to the default value of 128, is too small to accomidate the additional ILM memory added to the partition. 
Answer/Solution
FIX:The Virtual Partitions Administration Guide Page 185 has additional information on memory granules. 
 
From the error above, the ilm granules size is too small after adding additional memory and converting all CLM (cell local memory) to ILM (interleave memory).    Your current ILM and CLM granule sizes are 128, which is the default.   There are known performance issues (very long boot times etc...) with having a very small granule size.  

=== Solution ===

  * Config des vPars

=> booter en mode "nPar"

=> Recréer les vPars en utilisant vparstatus -v pour récup la config.
