You must configure the Data ONTAP software before you can
use these servers with the SAN Volume Controller.
Use one of the following methods to create an external
root volume:
- Create a VDisk on your SAN Volume Controller and
map it to your server.
- Partition and zone a back-end storage controller so that your
server can directly access a suitable volume to use as its root volume.
Before you configure the Data ONTAP software, the IBM® service
representative must
have installed the SAN Volume Controller.
After
the prerequisite task is complete, use the following general steps
to configure your Data ONTAP software:
- Zone the server to the SAN Volume Controller on
the fibre-channel SAN. Ensure that exactly two paths exist between
the server and each I/O group on the SAN Volume Controller.
For redundancy, configure the switch zoning so that host bus adapter
(HBA) port A in the server is zoned with a single connection to SAN Volume Controller node
A in an I/O group, while HBA port B in the server is zoned with a
single connection to SAN Volume Controller node
B in the same I/O group. When you use a SAN Volume Controller cluster
with multiple I/O groups, each HBA port in the server should be zoned
to one SAN Volume Controller node
in each I/O Group.
- Create the host system on the SAN Volume Controller,
using the worldwide port names (WWPNs) of the HBAs in the server.
For clustered server configurations, create a single host system on
the SAN Volume Controller, using the combined WWPNs of the HBAs in
all of the servers that participate in the cluster. Map the VDisks
to the host system as required.
- Create aggregates and volumes on your server using the instructions
in your host system publications.
