I have the following setup:
I have the following issues:
1. In IRST ports 4 and 5 show as EXTERNAL, when they definitely are INTERNAL.
2. Almost every time I reboot this machine IRST starts a 7 hr rebuild of the RAID5 array!
I'm thinking the two issues are related and need a way to fix ports 4 & 5 so they are read as internal. I tried the information found in http://msdn.microsoft.com/en-us/windows/hardware/gg463521.aspx http://msdn.microsoft.com/en-us/windows/hardware/gg463521.aspx but it had no effect.
Sounds like a variant of a problem I have encountered in which IRST 1.1.2 repeatedly does "Verify and Repair". I can resolve the problem by opening IRST and cancelling the R&V. IRST then shows the RAID array functioning normally. That might break the cycle for you.
The problem disappeared on my system when I installed 10.6.0.1002. Not only that but the rebuilds are much, much faster when needed. Hope it works for you too. --rbl--
