Setting Target Sessions for a New Device

When you define and mount multiple devices for the ISMData pool, all storage-space backups still go to the first device. You can send storage-space backups or logical-log backups to multiple devices at the same time.

To use multiple devices

Start ISM in the usual way (ism_startup).
Define and label all devices (up to 4).
Shut down ISM in the usual way (ism_shutdown).
Enter the following command at the prompt:
```
nsradmin
```
At the nsradmin prompt, enter the following command:
```
print NSR device
```
To update the target sessions variable for your configured devices, enter the following command. You need to enter this command only once to apply it to all configured devices.
```
update target sessions: 1
```
The following information is displayed for each device:
```
update resource id: resource_id
target sessions: 1;
Update?
```
Enter y.
Restart ISM in the usual way (ism_startup).
