Unisphere and Unisphere Central 2020 R1 Administrator's Guide

Create Multiple Volumes Simultaneously

You can create multiple volumes at a time.

1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of Unisphere Central.
2. From the STORAGE menu, click Volumes.
   The Volumes view is displayed.
3. In the Volumes view click (New), and select New Volume.
   The New Volume dialog box opens.
4. In the Volume Count field, type the number of volumes to create.
5. In the Name field, type a base name for the volumes. Each volume is named with a combination of the base name and the volume number.
6. In the Configured Size field, type a size for the volumes.
   The storage units are Bytes, KB, MB, GB, or TB.
7. In the Volume Folder pane, select the parent folder for the volumes.
8. (Optional) Configure the remaining volume attributes as needed.
   • Import To Lowest Tier—Select this check box to force all data that is written to the volume to the lowest storage tier configured for the volume. Enabling this option decreases performance for the volume.
     NOTE When the Import To Lowest Tier check box is selected, snapshots are no longer automatically created, snapshot profiles cannot be edited, and the volume does not adhere to storage profiles.
   • Show In Live Migration Recommendation—Select this check box to add the volume to the list volumes available for Live Migration.
   • Server—Select a server to which to map the volume.
   • Advanced Mapping—When a server is selected, click Advanced Mapping to configure LUN settings, restrict mapping paths, configure multipathing, or present the volume as read-only.
   • Preallocate Storage—When a server is selected, select the Preallocate Storage check box to allocate storage to the volume before the volume is mapped to the server.
     NOTE When a volume is preallocated, the Storage Center allocates all of the space on the volume to the server. The Free Space of the volume is 0 MB and the Used/Active Space of the volume is the equal to the size of volume on Storage Center. To keep the volume preallocated when it is formatted on the server, the SCSI UNMAP feature must be disable on the server.
   • Snapshot——Click Change to select snapshot profiles for the volume.

   The following QoS Profiles & Tiering options are available only if they are enabled in the Storage Center Settings dialog box:

   • Storage Profile—Select the storage profile to assign to the volume. Selecting the Recommended (All Tiers) storage profile allows the volume to take full advantage of data progression.
   • Storage Type—Select the storage type to assign to the volume.
   • Volume QoS Profile—Select the volume QoS profile to assign to the volume.
   • Group QoS Profile—Select the group QoS profile to assign to the volume.

   The following Data Reduction Profile options are available only if they are enabled in the Storage Center Settings dialog box:

   • Select Compression to enable data compression and reduce disk space usage.
   • Select Deduplication with Compression to apply deduplication and compression to new volumes.
   NOTE The data compression setting is applied to all volumes that share one or more snapshots with this volume. These shared volumes are referred to as siblings in the message displayed.
9. Click OK.
