Do you usually zone hosts with each io group of a SVC cluster or do you zone hosts only with one io group ?
The zoning is more easy when you can zone hosts with each io group. It will also permit to move a Vdisk to another io group (movevdisk -iogrp) without changing zoning.

Re: SVC host io group zoning2013-02-11T13:18:42Z in response to SystemAdminI zone them to every IO group. It only matters from a convenience perspective since a vdisk is only available as a target in one IO group at a time.
There may be instances where you configure a host to actually use different vdisks across different IO Groups to utilize multiple node CPUs and the cache on each, but that will need to be carefully tailored to each scenario.
