Configuration 3:
Configuration 3 allows up to two redundantly configured hosts to view a specific zone group of drives. Each
host will be able to view up to 30 drives that are mapped to both IOMs. Each zone group will display all of the
devices that are contained within that zone. If a drive slot is not populated, it will still be part of that zone group,
but it will not display any results in enclosure management until the drive slot has been populated. In this
Configuration, the enclosure is divided into two zone groups as shown in the image below represented by two
different colors. Each zone group matches to three SAS ports on each side of the rear IOM to allow for the
connections to two different hosts.
• In-band management: Configuration 3 can be initiated in the sg_senddiag command in-band by using 03
in the Zoning Configuration option. See: sg_senddiag Command on page 168 for the actual senddiag
commands.
