66 Provisioning the system
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 explicitly map multiple volumes
1. In the Configuration View panel, right-click Vdisks or a vdisk and then select Provisioning > Map
Volumes.
2. In the main panel, select the volumes to change. To select or clear all volumes, toggle the checkbox in
the heading row.
3. In the Maps for Selected Volumes table, select the host to change access for.
4. Select Map.
5. Either:
• Map the volumes to the host by setting a starting LUN, selecting ports, and setting access to
read-only or read-write.
• Mask the volumes from the host by setting a starting LUN, selecting ports, and setting access to
no-access.
6. Click Apply. A message specifies whether the change succeeded or failed.
7. Click OK.
Changing a volume's default mapping
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 the default mapping
In the Configuration View panel, right-click a volume and select Provisioning > Default Mapping. The main
panel shows the volume's default mapping:
• Ports. Controller host ports through which the volume is mapped to the host.
• LUN. Volume identifier presented to the host.
• Access. Volume access type: read-write, read-only, no-access (masked), or not-mapped.
To modify the default mapping
1. Select Map.
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. Each mapping that uses the default settings is updated.
