Prior to accessing the 'Volumes' via SSDPC, the StorSimple volumes need to be created on the Web UI, then assigned to appropriate appliaction servers and user should ensure that application servers can mount and use these volumes. This page will describe how to mount your volumes (on your windows system), volume types supported by StorSimple and the various operations that can be performed on these volumes such as refreshing, rescanning or deleting once these volumes are discovered.

Mounting StorSimple Volumes

On your Windows system, perform the following steps:

  • Launch Microsoft iSCSI initiator.
  • Supply one of the interface IP addresses as the target portal or discovery IP address.
  • Perform a quick connect and once the appliance is connected, the volumes will become accessible to your Windows system. For more information on using the Microsoft iSCSI initiator, see the section titled “Connecting to an iSCSI target device” at the following URL:
  • Launch Server Manager and open the Disk Management snap-in.
  • Initialize your volumes by performing the following steps:
    • Right-click the discovered disk and from the context menu select 'Initialize Disk'.
    • In the 'Initialize Disk' dialog, select the disks that you want to initialize and click 'OK'.
  • To format a basic volume, perform the following steps:
  • Select a volume that you wish to format and right-click to invoke the context menu.
  • Select 'New Simple Volume'.
  • You will now be guided through the configuration by a 'New Simple Volume Wizard'.
  • Specify the volume size.
  • Supply a drive letter.
  • Configure the volume as 'NTFS' file system.
  • Specify a 64KB allocation unit size.
  • Perform a quick format.
  •  For a multi-partition volume, see the section titled "Partitions and Volumes" at the following URL:


 LisdtStorSimple Supported Volumes

The following types of StorSimple volumes are supported:

  • Basic Volumes - support only simple volumes.
  • Dynamic Volumes - the following types of dynamic disks are supported.
    • Simple Volumes - comprising of a single partition on a single dynamic disk.
    • Dynamic Volumes with Multiple Partitions - comprising of multiple partitions on a single dynamic disk.
    • Dynamic Volumes with Mirroring (RAID - 1) - comprise of two disks and provide fault tolerance. Refer to the section 'Mirror Dynamic Volumes' to learn more about these volumes.
  • Cluster Shared Volumes - are volumes that are simultaneously available to directly read from and write to by all nodes in a Microsoft® Failover Cluster. Only limited backup operations are permitted for these volumes.


Volumes Node

A left click on ‘Volumes’ node in the DPC window displays all the mounted volumes, including the StorSimple volumes, local volumes, and any other third-party volumes discovered through the iSCSI initiator.




The StorSimple Volumes are defined by:

  • Name– is the drive letter assigned to each of the discovered volumes. 
  • Appliance – will be defined for all StorSimple appliances connected to MMC UI host and refers to the IP address of the StorSimple appliance.
  • Appliance Volume Name – is the volume name defined in the StorSimple web UI for that particular volume.
  • Access Path(s)– is the drive letter or mount point by which the volume is accessible on the host.
  • Offline – describes whether the given volume is connected to the network or not. This field is set through the web UI on the appliance under ‘General’ tab when configuring the Volumes. On the MMC UI, this field should typically never be true.
  • Volume Serial Number (VSN) – is a number assigned to the volumes. This number is typically determined by the date on the current computer when the volume was formatted. This feature is helpful in ascertaining if a volume is present or not, and to detect if the given volume was exchanged for another one.


Note.png Note: All StorSimple volumes are auto discovered once you are connected through iSCSI to the StorSimple appliance. If the volumes do not appear, click the ‘Refresh’ link in the Actions Pane.


This page also discusses the following functions associated with the 'Volumes' node -


Deleting a Volume

The user can delete a volume from the Volumes container, which deletes it from the Web UI.  The user is presented with a Confirmation dialog to proceed with the deletion. Clicking on Accept will now delete the selected volume.   




Note.png Note: A volume can only be deleted if it is not a part of any volume group.The delete option will be grayed out if the volume selected is a part of any volume group.

Deleting a Volume with multiple partitions

Deleting a volume with multiple partitions will delete all the partitions simultaneously.  The delete operation will not be available independently for the partitions.


Refresh a Volume

Right-click on Volumes node to select the 'Refresh' option and refresh the volume list as shown below.




Rescan a Volume

You can right-click on Volumes and choose to refresh the volume list or rescan for new volumes. Choosing this option will synch up with the appliance. The same can be achieved through re-launching the MMC Snap-in.  




Mirror Dynamic Volumes

A mirror dynamic volume consists of two plexes backed by two separate disks. When the mirror volume is in sync, both the plexes contain identical data. If the mirror is broken, then it results in two simple dynamic volumes from the plexes associated with the former mirror volume.

For each mirror volume containing at least one StorSimple volume, one plex in the mirror is identified as the “backup plex”. The plex identified as the backup plex will always be the last StorSimple volume in the mirror plex collection.

Some examples:
•    Mirror1

  • Plex1 (Non-StorSimple Volume)
  • Plex2 (StorSimple Volume ) → backup plex

•    Mirror2

  • Plex1 (StorSimple Volume) → backup plex
  • Plex2 (Non-StorSimple Volume)

•    Mirror3

  • Plex1 (StorSimple S3 Volume)
  • Plex2 (StorSimple Azure Volume) → backup plex

•    Mirror4 (no backup plex)

  • Plex1 (Non-StorSimple Volume)
  • Plex2 (Local Hard Drive)


A representation of the backup plex can be viewed in the Volumes node as a normal volume. The backup plex volume will show the mirror volume’s mount point and the StorSimple volume that backs the backup plex.
