Frequently asked questions...
- What is a volume?
A volume is a container in which applications, databases, and file systems store data. It is the logical component created for the host to access storage on the storage array. - Why am I seeing a capacity over-allocation error when I have enough free capacity in a volume group to create volumes?
The selected volume group might have one or more free capacity areas. A free capacity area is the free capacity that can result from deleting a volume or from not using all available free capacity during volume creation. - How does my selected workload impact volume creation?
During volume creation, you are prompted for information about a workload’s use. The system uses this information to create an optimal volume configuration for you, which can be edited as needed. Optionally, you can skip this step in the volume creation sequence. - Why aren't these volumes associated with a workload?
Volumes are not associated with a workload if they have been created using the command line interface (CLI) or if they have been migrated (imported/exported) from a different storage array. - Why can’t I delete the selected workload?
This workload consists of a group of volumes that were created using the command line interface (CLI) or migrated (imported/exported) from a different storage array. As a result, the volumes in this workload are not associated with an application-specific workload, so the workload cannot be deleted. - How do application-specific workloads help me manage my storage array?
The volume characteristics of your application-specific workload dictate how the workload interacts with the components of your storage array and helps determine the performance of your environment under a given configuration. - How does providing this information help create storage?
The workload information is used to optimize the volume characteristics such as I/O type, segment size, and read/write cache for the workload selected. These optimized characteristics dictate how your workload interacts with the storage array components. - What do I need to do to recognize the expanded capacity?
If you increase the capacity for a volume, the host might not immediately recognize the increase in volume capacity. - Why don't I see all my pools and/or volume groups?
Any pool or volume group to which you cannot move the volume does not display in the list. - What is segment size?
A segment is the amount of data in kilobytes (KiB) that is stored on a drive before the storage array moves to the next drive in the stripe (RAID group). Segment size applies only to volume groups, not pools. - What is preferred controller ownership?
Preferred controller ownership defines the controller that is designated to be the owning, or primary, controller of the volume. - What is Automatic Load Balancing?
The Automatic Load Balancing feature provides automated I/O balancing and ensures that incoming I/O traffic from the hosts is dynamically managed and balanced across both controllers. - When would I want to use the assign host later selection?
If you want to speed the process for creating volumes, you can skip the host assignment step so that newly created volumes are initialized offline. - What do I need to know before creating a remote storage connection?
To configure the Remote Storage feature, you must directly connect the remote and local storage systems via iSCSI. - Why am I being prompted to remove my remote volumes?
If you have the Remote Storage feature, the storage array displays a message when it reaches its maximum number of remote volumes. It automatically detects any unused remote volumes and prompts you to remove them. - Why don't I see all my volumes on my destination array?
If you have the Remote Storage feature, you might notice that some volumes do not display in the list of local destination candidates due to block size, capacity, or volume availability. - What do I need to know about the remote volume in an import?
If you have the Remote Storage feature, be aware that the remote volume is the volume from the remote storage array where the data originates. - What do I need to know before starting a remote storage import?
If you have the Remote Storage feature, be aware that the remote storage import allows you to copy data from a volume on a remote storage system to a local destination volume on a local DE Series storage system.
