or for one or more selected rows, and it can be displayed in row format or column format. The exported CSV file contains all of
the data in the table including information that is displayed in the hover panels.
1. Select one or more rows of data to export from a table that has an Export to CSV button.
2. Click Export to CSV. The Export Data to CSV panel opens.
3. Click All to export all of the data within the selected table, or click Selected to export only selected files.
4. Click Rows to export the data in row format, or Columns to export the data in column format.
5. Click OK. The data is exported to a CSV file.
Signing in and signing out
Multiple users can be sign in to each controller simultaneously.
For each active PowerVault Manager session, an identifier is stored in the browser. Depending on how your browser treats this
session identifier, you might be able to run multiple independent sessions simultaneously. For example, each instance of Internet
Explorer can run a separate PowerVault Manager session. However, all instances of Firefox, Chrome, and Safari share the same
session.
NOTE: For best security, Sign out when you are ready to end your session. Do not close the browser window unless you are
certain that it is the only browser instance.
Sign in
1. In the web browser address field, type https://<IP address of a controller network port> and press
Enter.
The Sign In page opens. If the Sign In page is not displayed, verify that you have typed the correct IP address.
NOTE: HTTPS is enabled by default. To enable HTTP, see Enable or disable system-management settings.
2. Type the username of a PowerVault Manager user in the User name field.
3. Type the password of the PowerVault Manager user in the Password field.
4. To display the interface in a language different than the one configured for the user, select the language from the language
drop-down menu.
Language preferences can be configured for the system and for individual users. The default language is English.
5. Click Sign In.
The Home page or the Welcome panel is displayed.
Sign out
1. Click Sign Out, located in the upper right of the PowerVault Manager window.
2. In the confirmation panel, click Sign Out.
System concepts
About virtual and linear storage
This product uses two different storage technologies that share a common user interface. One uses the virtual method while
the other one uses the linear method.
Virtual storage is a method of mapping logical storage requests to physical storage (disks). It inserts a layer of virtualization
such that logical host I/O requests are mapped onto pages of storage. Each page is then mapped onto physical storage. Within
each page the mapping is linear, but there is no direct relationship between adjacent logical pages and their physical storage.
A page is a range of contiguous Logical Block Addresses (LBAs) in a disk group, which is one of up to 16 RAID sets that are
grouped into a pool. Thus, a virtual volume as seen by a host represents a portion of storage in a pool. Multiple virtual volumes
can be created in a pool, sharing its resources. This allows for a high level of flexibility, and the most efficient use of available
physical resources.
