Host connection (SAS Port)
Configuration 2:
Configuration 2 allows up to three redundantly configured hosts to view a specific zone group of drives.
Each host will be able to view up to 20drives 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 three zone groups as shown in the image
below represented by three different colors. Each zone group matches to a pair of SAS ports on each side
of the rear IOM to allow for the connections to three different hosts.
• In-band management: Configuration 2 can be initiated in the sg_senddiag command in-band by
using 02 in the Zoning Configuration option. See:
senddiag commands.
• Out-of-band management: Configuration 2 can be initiated in the out-of-band management by using
2 in the ZoningConfig option. The following are example Redfish POST and cURL commands:
