Hi all, I have two T5240 with LDOM and last night cause kernel patching on control domain and guest, I preferred put one mirror side in to offline state on the control domain, I tested the offline state with many reboot and was always ok ...one mirror "online" and one mirror "offline"...When I installed the kernel patch 142900-17 (with reconfigure reboot), I was surprise to see the rpool in resilvering and disk''s online state after "boot -r". Is this strange behavior or not ?? What''s happened ? Thanks in advance Fred -------------- next part -------------- An HTML attachment was scrubbed...
