Explicitly Mapping Multiple Volumes - HP P2000 G3 Reference Manual

CAUTION: Volume mapping changes take effect immediately. Make changes that limit access to volumes
when the volumes are not in use. Before changing a mapping's LUN, be sure to unmount a mapped
volume from a host system.
IMPORTANT:
replication. Attempting to do so could interfere with replication operation.
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 change default mapping for multiple volumes
1. In the Configuration View panel, right-click Vdisks or a vdisk and then select Provisioning > Map
Volume Defaults.
2. In the main panel, select the volumes to change. To select or clear all volumes, toggle the checkbox in
the heading row.
3. Select Map.
4. Either:
• Map the volumes to all hosts by setting a starting LUN, selecting ports, and setting access to
read-only or read-write.
• Mask the volumes from all hosts by setting a starting LUN, selecting ports, and setting access to
no-access.
5. Click Apply. A message specifies whether the change succeeded or failed.
6. Click OK.

Explicitly mapping multiple volumes

For all volumes in all vdisks or a selected vdisk, you can change access to those volumes by a specific host.
When multiple volumes are selected, LUN values are sequentially assigned starting with a LUN value that
you specify. For example, if the starting LUN value is 1 for 30 selected volumes, the first volume's mapping
is assigned LUN 1 and so forth, and the last volume's mapping is assigned LUN 30. For LUN assignment
to succeed, ensure that no value in the sequence is already in use. When specifying access through
specific ports, the ports and host must be the same type (for example, FC).
CAUTION: Volume mapping changes take effect immediately. Make changes that limit access to volumes
when the volumes are not in use. Before changing a mapping's LUN, be sure to unmount a mapped
volume from a host system.
IMPORTANT:
replication. Attempting to do so could interfere with replication operation.
NOTE: You cannot map the secondary volume of a replication set.
