This page enables you to create new disk-based volumes and to edit the media attributes of existing disk-based volumes.
You can perform the following tasks:
The following table describes the buttons and columns on the Disk Volumes page.
Field |
Description |
---|---|
New |
Click to add a new disk-based volume. |
Edit Media Flags |
Click to edit the attributes of the disk volume. |
Name |
The name of the disk-based volume. |
Resource |
For disk-based volumes this displays the full path to the directory where archive copies can be stored. For STK5800 volumes this displays the data IP address and data port. |
Host |
The server on which the disk-based volume is located. |
Usage (Capacity) |
The total amount of space used and the total capacity of the disk-based volume. |
Media Flags |
A characteristics of the disk-based volume. To view all media flags in a separate browser window, click the media flag in this column. |
In an archive policy, you can choose to send archive copies of your files to disk-based volumes. There are two types of disk-based volumes:
Disk Volume — Allows archiving to a directory in a mounted file system that has been assigned a volume name. These are referred to by the media type “Disk” in the archive pages of the SAM-QFS Manager.
STK5800 Volume — Allows archiving to the Sun StorageTek 5800 system. These are referred to by the media type “STK5800.”
Disk volumes can be located on a file system on the current server or on a different server. The file system on which the disk volumes are located can be any UNIX file system. However, if the file system is located on a server other than the current server, there must be at least one archiving file system configured on that other server.
There are no restrictions on the location of disk volumes on a file system, but disk volumes should reside on a disk other than where the original files that you are archiving reside. Also, commonly an entire file system is used as a single disk volume. It is then clear that all of the remaining space on the volume can be consumed for the purpose of storing archive copies which makes planning simpler.
STK5800 volumes allow archiving to a Sun StorageTek 5800 system. The Sun StorageTek 5800 is an online appliance with clustered disk-based storage nodes.
When configuring archiving, you should make more than one copy in a policy and write to more than one type of archive media. Also if you are configuring archiving to disk volumes and tape volumes, you should configure copy 1 to be disk volumes and the higher numbered copies to use tape volumes. This will help minimize tape loading because the Sun SAM software will preferentially stage from copy 1.
The Disk-Based Volumes tab is displayed under the Archive Management tab in the application. From the Disk-Based Volumes tab, you can create disk volumes and edit their media attributes and you can create STK5800 volumes.
