HSCLA27C, reserve_policy and LPM validation error.
A customer was attempting to move an LPAR from one POWER7 750 to another POWER7 750 using Live Partition Mobility (LPM). But he was receiving the following error message when performing an LPM validation.
This was an easy one to fix. The reserve policy on the hdisk on the VIOS (yes, it was a single VIO server not dual VIOS, don't ask why!) was set to PR_exclusive instead of no_reserve.
Once we changed the reserve_policy setting for hdisk2 from PR_exclusive to no_reserve, the LPM operation worked fine.
