This is why i asked you if you use a HMC - you don't, but use IVM instead.

The IVM screen says the total system memory is 16GB. Do you have all 32GB activated? IBM usually delivers its machines configured for CuOD (customer upgrade on demand) and you can use only a part of what is physically installed until you buy a license for the rest.

Did you check the error log? Maybe some memory/memory controller is broken and was deactivated by the system. Have you checked the ASMI?

I hope this helps.

NAME
unlockable_mem - OBSOLETE kernel tunable parameter DESCRIPTION
The tunable is obsolete and has been removed. Memory locking allows the privileged user to specify which pages need to remain in memory, and unaffected by the swap process. This fea- ture allows you to ensure that memory access times are unaffected by delays introduced by memory paging and swapping. For example, locking is a tool provided to privileged users on a system that is short on physical memory. Instead of having these privileged processes swap like the rest of the processes, they can lock portions of their address space. Once the pages are locked in for the privileged processes, they will no longer have to worry about memory contention. The unprivileged processes however, will have to compete for memory. provides you with a limiting factor on this privileged behavior, by setting the amount of memory which cannot be locked by user processes. WARNINGS
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed.
