NOTE: The system might be unable to delete a large number of volumes in a single operation. If you specified to delete a large number of volumes, verify that all were deleted. If some of the specified volumes remain, repeat the deletion on those volumes. Changing default mapping for multiple volumes For all volumes in all vdisks or a selected vdisk, you can change the default access to those volumes by all hosts. 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. CAUTION: Volume mapping changes take effect immediately. Make changes that limit access to volumes when the volumes are not in use. Before changing a volume's LUN, be sure to unmount/unpresent/unmap the volume. 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/present/map 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. In the main panel, a table shows all the volumes for the selected vdisk. 2. In the table, select the volumes to change. To select up to 100 volumes or clear all selections, toggle the checkbox in the heading row. 3. 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. Setting the default mapping to no-access will result in the LUN mapping being removed. 4. Click Apply. A confirmation dialog appears. 5. Click Yes to continue; otherwise, click No. If you clicked Yes, mapping changes begin. 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 volume's LUN, be sure to unmount/unpresent/unmap the volume. Changing default mapping for multiple volumes 65

Changing default mapping for multiple volumes

NOTE:
The system might be unable to delete a large number of volumes in a single operation. If you specified to
delete a large number of volumes, verify that all were deleted. If some of the specified volumes remain, repeat the
deletion on those volumes.
Changing default mapping for multiple volumes
For all volumes in all vdisks or a selected vdisk, you can change the default access to those volumes by all hosts.
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.
CAUTION:
Volume mapping changes take effect immediately. Make changes that limit access to volumes when the
volumes are not in use. Before changing a volume’s LUN, be sure to unmount/unpresent/unmap the volume.
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/present/map 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
.
In the main panel, a table shows all the volumes for the selected vdisk.
2.
In the table, select the volumes to change. To select up to 100 volumes or clear all selections, toggle the checkbox
in the heading row.
3.
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
.
Setting the default mapping to
no-access
will result in the LUN mapping being removed.
4.
Click
Apply
. A confirmation dialog appears.
5.
Click
Yes
to continue; otherwise, click
No
. If you clicked Yes, mapping changes begin. 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 volume’s LUN, be sure to unmount/unpresent/unmap the volume.
