Working with synchronous mirror groups
Adding host permission to a group
You can add host permission to a sync mirror group under the following conditions:
• You cannot add permission to a group that already has any permissions.
• You can add permission to multiple hosts when the group is defined as clustered.
To add host permission to a sync mirror group:
1. In the Sync Mirror Groups list, right-click a group name.
2. Select Manage > Manage Permission > Add Host Permission. The Select Host(s) screen appears.
3. In the Host(s) table, select the host to which to assign permission.
4. Click Add. The host appears in the Selected Host(s) table. To remove the host from the table,
select the host in the Selected Host(s) table, and then click Remove.
5. If necessary, modify the host’s permission:
a. In the selected host’s Permission column, click the permission. The field becomes a dropdown
box.
b. Select a permission from the dropdown box:
• Full—Read/write permission
• Read—Read only permission
• None—No permission
6. If necessary, repeat steps 3 through 5 to assign permission to additional hosts.
7. Click Next. The Select LUN screen appears.
8. To select the LUN, select one of the LUN options:
• Next free LUN (recommended)—VSM assigns the next free LUN available for presenting the
snapshot to hosts.
• Specified LUN—From the Specified LUN dropdown box, select the LUN for presenting the
snapshot to hosts.
9. Click Next. The Select DPM Group screen appears. The upper area of the screen displays the
DPM groups through which the host is registered.
10. Select a DPM group and click Add. The DPM group you selected is displayed in the lower area
of the screen.
11. Click Next. The Select preferred path screen appears.
12. Use the checkboxes to set one DPM in the DPM group as primary and one DPM as secondary.
NOTE:
If you click Finish without defining the primary and secondary DPMs, VSM defines these
roles automatically.
13. Click Next. A confirmation screen appears.
14. Click Finish. The host permission is added to the sync mirror group.
