In this section, how to create a new volume is explained.
In the [Settings] menu, select [Volume Configuration]. The Volume Configuration screen appears.
Follow the procedures below to create a volume.
In the [Group and Disk List], select the group or the disk.
Click <Unused> with a volume icon, and select an unused volume.
Selecting an unused volume will allow you to type in the volume attributes field (Volume Name, Volume Size, JRM, Physical Slice).
Type the volume name.
For information on assigning a volume name, see "Object Name."
Type the volume size in MB units, using numbers only.
Size and Cylinder Boundary
When the specified size does not match the cylinder boundary, it will automatically adjust by rounding up. For details, see "Volume Size."
Sets the value in the "Volume Size" field to the maximum available size.
Default is set to "on." Change the setting when you want to disable the just resynchronization copying feature.
When you select a stripe group or concatenation group in step 1, the setting will fail.
Sets the volume's physical slice attribute value.
on : a volume which consists of physical slices is created.
off: a volume without physical slices is created.
When you select a stripe group or concatenation group in step 1, the setting will fail.
After setting the attributes, click <Add>. A new volume will be created.
If you click <Reset>, creation of the new volume will be canceled.
After creating all volumes, click <Exit> and close Volume Configuration screen.
After creating the volume, the volume will be started. You can access to the volume using the following special files.
/dev/sfdsk/class name/rdsk/volume name
/dev/sfdsk/class name/dsk/volume name
Shared Class Volume Operation
Volume created in a shared class cannot be used from other nodes immediately. If you wish to access from other nodes, you must activate the volume from the node you wish to access. After activating the volume, the node which created the volume, and the node which activated the volume will gain access. However, since operating from two nodes could affect data consistency, you must be careful when operating the volume.
