NOTE: When mapping a volume to a host with the Linux ext3 file system, specify read-write access. Otherwise,
the file system will be unable to mount the volume and will report an error such as “unknown partition table.”
○ Ports. Port selections specify controller host ports through which initiators are permitted to access, or are prevented
from accessing, the volume. Selecting a port number automatically selects the corresponding port in each controller.
● To save a new mapping or edits to an existing mapping, in the Action column, select Save.
● To clear the mapping table and discard any changes, click Reset.
4. Once the list is correct, to apply changes, click Apply or OK.
A confirmation panel appears.
To discard the changes instead of applying them, click Reset.
5. Click Yes to continue. Otherwise, click No. If you clicked Yes, the mapping changes are processed.
6. To close the panel, click Cancel.
Remove mappings
You can remove one or more selected mappings between initiators and volumes.
1. Perform one of the following:
● In the Mapping topic, select one or more mappings from the table.
● In the Volumes topic, select at least one mapping in the Related Maps table.
2. Select Action > Remove Mappings. The Remove Mappings panel shows the selected mappings.
3. Click OK. The selected mappings are removed.
Removing all mappings
You can remove all mappings between initiators and volumes from the system.
1. In the Mapping topic, select one or more mappings from the table.
2. Select Action > Remove All Mappings. The Remove All Mappings panel opens.
3. Click OK. The mappings are removed from the system.
View map details
In the Hosts, Volumes, and Mapping topics, you can see basic information about mappings between hosts and volumes.
1. Perform one of the following:
● In the Hosts or Volumes topic, in the Related Maps table, select at least one mapping.
● In the Mapping topic, in the mapping table, select at least one mapping.
2. Select Action > View Map Details. The Map Details panel opens and shows the following information.
● Host Group. Identifies the host group to which the mapping applies:
○ -. The mapping does not apply to a host group.
○ host-group-name. The mapping applies to all hosts in this host group.
● Host. Identifies the host to which the mapping applies:
○ -. The mapping does not apply to a host.
○ host-name. The mapping applies to all initiators in this host.
● Nickname. Shows the nickname of the initiator, if a nickname is assigned. Otherwise, this field is blank.
● Initiator ID. Shows the WWN of an FC or SAS initiator or the IQN of an iSCSI initiator.
● Volume Group. Identifies the volumes to which the mapping applies:
○ -. The mapping does not apply to a volume group.
○ volume-group-name. The mapping applies to all volumes in this volume group.
● Volume. Identifies the volume to which the mapping applies.
● Access. Shows the type of access assigned to the mapping:
○ read-write—The mapping permits read and write access to volumes.
○ read-only—The mapping permits read access to volumes.
○ no-access—The mapping prevents access to volumes.
