Changing A Volume's Explicit Mappings - HP P2000 G3 Reference Manual

To delete the default mapping
1. Clear Map.
2. Click Apply. A message specifies whether the change succeeded or failed.
3. Click OK. Each mapping that uses the default settings is updated.

Changing a volume's explicit mappings

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.
NOTE: You cannot map the secondary volume of a replication set.
NOTE: When mapping a volume to a host using 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."
To view volume mappings
In the Configuration View panel, right-click a volume and select Provisioning > Explicit Mappings. The
main panel shows the following information about the volume's mappings:
• Type. Explicit or Default. Settings for an explicit mapping override the default mapping.
• Host ID. WWPN or IQN.
• Name. Host name.
• Ports. Controller host ports through which the host is mapped to the volume.
• LUN. Volume identifier presented to the host.
• Access. Volume access type: read-write, read-only, no-access (masked), or not-mapped.
To create an explicit mapping
1. In the Maps for Volume table, select a host.
2. Select Map.
3. Set the LUN and select the ports and access type.
4. Click Apply. A message specifies whether the change succeeded or failed.
5. Click OK. The mapping becomes Explicit with the new settings.
To modify an explicit mapping
1. In the Maps for Volume table, select the Explicit mapping to change.
2. Set the LUN and select the ports and access type.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping settings are updated.
To delete an explicit mapping
1. In the Maps for Volume table, select the Explicit mapping to delete.
2. Clear Map.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping returns to the Default mapping.
