Hi; We are experiencing a problem booting some partitions (AIX 6.1 and 7.1) in a Power7 795 with dedicated FC adapters,
from an EMC Symmetrix DMX4 3500. We have installed power path and followed all the procedures, so rootvg lives in a hdiskpower device.
The thing is that booting the partitions, sometimes they seem to loose the bootlist or cannot reach the boot devices from the bootlist and the boot fails with message "No operating system found", but if you boot to SMS menu and select de devces to boot or simply go to Select Boot Options -> Configure Boot Device Order -> Display Current Setting, it shows the bootlist, you just exit SMS menu and the partition boots ok.
Thanks in advance.
