We had a couple of servers hang/crash during LPMs recently and IBM & EMC support suggested we change all of our LPAR hdisks & hdiskpowers reserve_policys to no_reserve.  Which we did.  Now when we LPM a test LPAR sometimes we see all hdisks for a hdiskpower with a CONNECTION FAILURE errpt message & a FUNCTION DEGRADED errpt message for the hdiskpower (see below).  EMC says not to be concerned -> just informational messages.  My boss says losing all paths to a hdiskpower device can't be good.  What messages are 'normal' in errpt running LPM w/PowerPath?
