Severity: 2-Critical


The system might post the following error when the provisioned modules should be supported: 01071008:3: Provisioning failed with error 255 - 'Physical memory (6144MiB) insufficient for 3 or more modules.'


Not allowed to provision more than 3 modules.


VCMP guests and VE guests with memory between 5632 MiB and 6250 MiB.


Create VCMP guests with 4 or more CPUs. Configure the VE guests with more than 6250 MiB of memory available.

Fix Information

Three or more modules can be provisioned on VCMP guests and VE guests having 5632 MiB or more memory.

Behavior Change

You are now allowed to provision any number of combinations of modules on platforms with 5.5 GiB of memory or more so long as there are resources available. Previously, 3 or more modules were not allowed to be provisioned on platforms with 6 GiB or less. Note that Application Acceleration Manager (AAM) cannot be provisioned with any other module; AAM can only be provisioned standalone.
