6. To remove an explicit mapping:
a. In the Assign Host Access Privileges panel, select a host node.
b. Click Unmap It.
When processing is complete, the mapping is removed from the page.
Managing Volume Mappings on a SAS System
Caution – Volume mapping changes take effect immediately. Make changes that
limit access to volumes when the volumes are not in use. Be sure to unmount a
mapped volume from a host system before changing the mapping’s LUN.
To manage host-to-volume mappings:
1. Select Manage > Volume Management > Volume Mapping > Map Hosts To Volume.
For each virtual disk, the virtual disk panel shows a status icon; the name, RAID
level, size, number of disk drives, and number of volumes; and utility status, if any.
2. Select a virtual disk.
The selected virtual disk’s volume names, sizes, and types are displayed.
3. Select a volume.
The Current Mappings panel shows which hosts have access to the selected volume.
For the selected volume you might see the following mappings:
■ All Hosts – Shows the settings used by all hosts to access the volume. This entry
is displayed only if no hosts are explicitly mapped. If a host is explicitly mapped,
All Hosts changes to All Other Hosts.
■ WWN-value – Shows an explicit mapping between a host and the volume.
■ All Other Hosts – Shows the access settings used by all hosts except by explicitly
mapped hosts. This entry is displayed only if hosts are explicitly mapped. If no
host is explicitly mapped, All Other Hosts changes to All Hosts.
For each host entry, the WWN and nickname, LUN, and target-port access
privileges are shown. The access privilege for a target port can be read-write, read-
only, or none (no access; masked).
4. To change the default mapping for the selected volume:
a. In the Add Or Modify A Mapping panel, select All Other Hosts.
