Assuming the app in zone1 and zone1 are all part of zone1_sg: hagrp -freeze zone1_sg hasys -freeze nodea Patch as normal, reboot. hasys -unfreeze nodea hagrp -unfreeze zone1_sg I suggest freezing just in case you accidentally boot to multi-user mode and vadclientd.bin comes up and starts "fixing" things. > - repeat above process for Node B/Zone 2 > - Test failover of Service Groups/Zones between nodes. Again with freeze/unfreeze. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
