I have installed a few 11gR2 RAC on AIX 6.1 (extended RAC architecture) Hit two issues: one is when one storage array is turned off the whole system hangs for 10 minutes, I am not sure what that can be, have a SR opened for 5 weeks with no response from support another is that when ASM is down the local instances sometimes doe not get restarted, have a SR open for 6 weeks with no response from support Other than thhose issues crsctl stat res shows funny outputs but not really a problem Thanks -- LSC On Thu, Feb 25, 2010 at 7:00 PM, Ram Raman <veeeraman@xxxxxxxxx> wrote: > Listers, > > We are planning to implement 11.201 RAC on AIX 6.1.
