How to Define a Silo Device (nsradmin -c)

1. Become root on the Backup server or storage node machine that uses the silo.

2. Enter nsradmin -c (visual mode) to edit the silo definition.

   1. Select Dynamic and Hidden from the Options menu.

   2. Select nsr jukebox.

   3. Select Edit.

3. Add the new device name to the Devices attribute.

   You must enter a comma between the device names.

4. In the Number Devices attribute, increase the number of devices by one.

5. Add a null string with comma to each of the following attributes, before the final semi-colon (,""):

   1. Loaded Volumes

   2. Loaded Barcodes

   3. Loaded Slots

6. Add the name of the new device in the STL Device Names attribute.

   Surround the device name with quotation marks.

7. Add the following entry to the Allocated Devices attribute:

   ,No

Example: Defining a Silo Device

The following examples show selected nsradmin attributes before and after you add a device.

Before:

devices: /op1;
number devices: 1;
allocated devices: No;
loaded volumes: "";
loaded bar codes: "";
loaded slots: "";
STL device names: "0,0,2,0";

After:

devices: /op1, /op2;
number devices: 2;
allocated devices: No, No;
loaded volumes: "", "";
loaded bar codes: "", "";
loaded slots: "", "";
STL device names: "0,0,2,0", "0,0,2,1";

If you define multiple devices in a silo for Backup to use, you do not need to specify them in any particular order in the Jukeboxes resource. The only restriction is that the list of device names in the Devices attribute must be in the correct order with respect to the list in the STL Device Names attribute.
