The procedure to create volumes is as follows:
On the global navigation tab, click Storage.
The registered ETERNUS Disk storage systems are displayed on the Main pane.
On the Main pane, click the target ETERNUS Disk storage system.
On the Category pane, click Volume.
On the Action pane, click Create under Volume.
The information input screen is displayed.
Enter the necessary information, and then click Next.
The information confirmation screen is displayed.
Confirm the information, and then click Create.
Note
The maximum capacity of volume that can be created is the largest contiguous free space in the RAID group. When fragmentation has occurred in the RAID group, the largest contiguous free space is less than the total free capacity of the RAID group.
If the volume cannot be created because of insufficient free capacity of the RAID group, even though you specified capacity less than the total free capacity of RAID group, use the ETERNUS Web GUI to verify the free space of the RAID group.
In the following cases, the maximum number of volumes cannot be created.
There is a Thin Provisioning Pool in the storage device.
There is a concatenation volume in the storage device.
There is a REC Disk buffer in the storage device.
There is a volume which is executing RAID Migration.
There is a volume which is executing Thin Provisioning Volume balancing.
When creating a volume to the RAID group using Self Encrypting Drive (SED) disk, specify "No" for volume encryption.
Volume creation may take several minutes to several hours depending on the device configuration. When creating a number of volumes at one time, consider the processing time to carry it out.
There are storage device models that cannot set the encryption mode from the Web Console. Refer to "Volume Management" in the ETERNUS SF Storage Cruiser Operation Guide for details.
In the Web Console, the volume that is LUN concatenated and Wide Striping Volume cannot be created.
