3 Example: Configuring zoned SAS storage enclosures
Configuring zoned SAS storage enclosure includes the following tasks, performed in sequence:
1.
Disabling Multi-initiator Mode.
NOTE:
If tape autoloaders/libraries or shared SAS storage enclosures are also connected
to the switch and multiple server device bays will need access to the same switch-port zone
groups, Multi-initiator Mode must be Enabled.
2.
Creating one or more drive-bay zone groups.
3.
Assigning each zone group to the server device bay that needs access to the storage associated
with that zone group.
4.
Capturing the configuration for safekeeping. (Strongly recommended. Available only in VSM
CLI.)
5.
Configuring disk drives in the storage enclosure into logical storage units (LUNs) using the
management utility supported by the storage enclosure.
NOTE:
•
The MDS600 is an example of a zone SAS storage enclosure.
•
A RAID controller is installed in the server and is used for its RAID configuration capabilities.
The zoned SAS storage enclosure does not includes a RAID array controller.
•
Use drive-bay zone groups to configure zoned SAS enclosures, so that the group of drive bays
is presented to the server device bay as if it was directly connected to that server device bay.
•
Each server device bay that needs access to the external storage must be assigned a zone
group.
◦
A server device bay can be assigned multiple zone groups.
◦
A drive-bay zone group can be assigned to only one server device bay.
◦
Unpopulated enclosure server device bays can be assigned zone groups.
•
The disks in the enclosure are configured into logical storage units (LUNs) using host based
configuration utilities (such as ACU or ACU CLI) running on the server with access to the zone
group containing the drive bays.
The following example illustrates creating a zone group of 10 disk drive bays and then assigning
that zone group to a server bay. For more information about these tasks, see the following sections:

“Advanced Settings task” (page 36)

“Create Zone Group task” (page 37)
