Adding Storage Managers to Storage Groups
You can add unassigned Storage Managers to a Storage Group to increase its storage capacity. This is typically done
when adding a new Engine to your Avid ISIS system. This process initiates a redistribution of the files in the
existing Storage Group to include the new Storage Manager. For more information, see
“Redistributing Data” on
page 81
.
To add Storage Managers to a Storage Group:
1. From the Management Console home page, click Storage Groups in the System section.
The Storage Groups page opens.
2. In the Storage Groups list, select the Storage Group where you want to add Storage Managers, and then do one
of the following:
t Click Details.
t Double-click the Storage Group name.
The Details panel displays all the information on the selected Storage Group.
3. In the Storage Managers panel, select all the spare Storage Managers you want to add to the Storage Group.
n
If you have two Management Domains in the ISIS | 7500, check the Domain ID column and select Storage Managers
from the same domain. You cannot add Storage Managers to a Storage Group with a different Domain ID. Storage
Groups cannot span Management Domains.
4. Click Add to add the selected spare Storage Managers to the Storage Group.
The Storage Managers panel refreshes to display the selected Storage Managers added to the Storage Group.
5. (Option) Click Revert to undo any modifications made to the Storage Group information.
6. Click Apply.
The Storage Managers are added to the Storage Group.
- The shared storage network performs a redistribution of any data on the Storage Managers. The amount of
time required for the redistribution depends on the amount of data in the Storage Group.
- The configuration change counter for all affected Workspaces is incremented by one.
n
After 20 configuration changes, the system advises you to perform a full redistribution. You can suspend and resume
the redistribution as needed. For more information, see “Suspending and Resuming Redistribution” on page 85.
Creating New Storage Groups
A Storage Group is a set of physical Storage Managers that store a subset of the complete set of media files
accessible within a shared storage environment. You can create up to 32 Storage Groups.
n
You must add Storage Managers to the file system before you can create any Storage Groups. For more information,
see “Binding Storage Managers to the ISIS File System” on page 38.
n
If you have bound Storage Managers to the ISIS file system but you have not created any Storage Groups, the Create
Storage Groups dialog box opens by default when you select the Storage Groups list.
