In this case, the controller’s performance
is highly elevated. You need not
consider different host ports because
the bindings between hosts and storage
groups are applied to all host ports.
As the illustration shows, LUNs are
assigned according to each host’s
WWPN (World Wide Port Name).
Therefore, you need to set the host
WWPN first. Each host can recognize
LUNs as paths to virtual disks, instead of
individual disks.
To set up symmetric storage groups, first
add host(s).
Add hosts
In the symmetric storage main screen, click Host > Add.
Host ID Select a Host ID from the drop-down menu. A
maximum of 32 hosts can be added to the
controller.
WWPN Each FC port needs a WWPN for communicating
with other devices in an FC domain. Users can
choose each WWPN of Fiber HBA from the
‘Choose from detected hosts’ box or directly
enter the WWPN in this field.
SAS Address For SAS controller each SAS port needs a SAS
Address for communicating with other devices in
an SAS domain.
Host Name Use the system default name as hostx. ‘x’ is the
Host identifier.
OR
Uncheck the ‘Use system default name’ box and
enter the name in the Name field. The maximum
name length is 63 bytes.
HG ID Select a Host Group ID from the drop-down
menu. You can select from hg0 to hg31 or No
group.That is must to set for symmetric method.
