Storage Essentials 5.1 User Guide 461
• Automatically Assign Volume to Storage Port based on - Select one of the following:
•*Most unused ports (the number of LUNs assigned) - Assigns a volume to a FA port
based on how often a port is used. Unused ports have a better chance of having a
volume assigned to them as compared to frequently used ports. This option helps you
spread out the traffic.
•*Linked port if there is any - A linked port is more likely to be assigned a volume. The
management server looks for any storage system port that is zoned to the selected host
bus adapter. If the management server cannot find a storage system port zoned to the
selected HBA, the management server selects a port with the least amount of LUNs.
*You can only access these options if Automatically Assign Volume to Storage Port
Based on is selected.
• Verify that in a multipath configuration, storage system ports do not connect to the
same switch - This option makes sure the multipath configuration is preserved. A storage
system ports should not get connected to the same switch.
• Assign a LUN number automatically - Do not select this option if you want to assign a
LUN number manually.
2. Click OK when you are done with your selections.
Zone Customize Dialog
When the option, Automatically create new zone if no existing zone containing HBA and
storage system ports is detected, is selected in the zone customize dialog ( ), the
management server automatically selects a zone that meets its criteria. If the management server
cannot find a zone that meets its criteria, it creates a zone on the fly. You set the criteria for
automatically configuring zones by selecting one of the following options:
• *Create new zone if there is no zone containing ONLY the selected zone members (HBA
and storage system ports) - The management server checks if an identical zone exists. An
identical zone contains only same HBA and storage system ports you selected. If the zone
contains additional members, it is not considered to be identical.
• If an identical zone exists, it is selected in the Zone pane.
• If an identical zone does not exist, the management server asks you to name a zone that will
be created. The new zone appears in the Zone pane, even though it is not created until the
job runs.
• *Create new zone if there is no zone containing AT LEAST the selected zone members -
The management server tries to find a zone that contains the HBA and storage system ports you
selected.
• If a zone contains additional members, the management server selects that zone in the Zone
pane.
• If the management cannot find a zone containing the HBA and storage system ports you
selected, the management server asks you to name a zone that will be created. The new
zone appears in the Zone pane, even though it is not created until the job runs.
*To enable one of these options, the option, Automatically create new zone if no existing
zone containing HBA and storage system ports is detected, must be selected.
