Tivoli Storage Manager for Windows Administrator's Guide
Administrators must perform the following tasks to share TSM tape library
devices over a SAN:
Before sharing library devices in a SAN library,
administrators must set up server communications for the servers that will
share library devices.
- Configure each server for Enterprise Administration and define the servers
to each other, using the cross-define function. See Setting Up Communications Among Servers for details. Administrators can use either the DEFINE
SERVER command or the Web interface. If using the Web interface, follow
this path:
- Network View
- Other Servers
- Options
- Define Server
- Fill out the form
Note: | Administrators must set up each server with a unique name.
|
- Verify that the library manager server is running, and start it if it is
not:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Service Information in the Server Utilities tree in the left
panel. The TSM Services tab appears in the right
panel.
- Check to see if the library manager server is running. If it is
stopped, right click on the server name. A pop-up menu appears.
- Click Start in the pop-up menu.
- Verify that the TSM device driver is running, and start it if it is
not:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Service Information in the Server Utilities tree in the left
panel. The TSM Services tab appears in the right
panel.
- Check to see if the TSM device driver is running. If it is stopped,
right click TSM Device Driver. A pop-up menu appears.
- Click Start in the pop-up menu.
- Obtain the library and drive information for the shared library
device:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Device Configuration in the TSM Server Utilities tree (left
pane). The Device Configuration tab appears in the right
pane.
- Click Refresh in the right pane. Updated library and
device information appears.
- Configure a library named SANGROUP.
define library sangroup libtype=scsi device=lb0.0.0.2 shared=yes
- Define the drives in the library.
define drive sangroup drivea device=mt0.1.0.2 element=1030
define drive sangroup driveb device=mt0.1.0.2 element=1031
- Define at least one device class. Use a low mount retention time
(1-2 minutes) and mount wait time for shared library devices.
Set the mount wait times to different values for each server.
define devclass tape devtype=dlt mountretention=1 mountwait=10
library=sangroup
- Check in the library inventory. The following example checks all
volumes into the library inventory as scratch volumes.
checkin libvolume sangroup search=yes status=scratch
checklabel=barcode
- Set up a storage pool for the shared library with a maximum of 50 scratch
volumes.
define stgpool backtape tape description='storage pool for
shared sangroup' maxsize=nolimit collocate=yes maxscratch=50
Note: | Administrators must define the library manager server before setting up the
library client server.
|
- Verify that the library client server is running, and start it if it is
not:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Service Information in the Server Utilities tree in the left
panel. The TSM Services tab appears in the right
panel.
- Check to see if the library client server is running. If it is
stopped, right click on the server name. A pop-up menu appears.
- Click Start in the pop-up menu.
- Verify that the TSM device driver is running, and start it if it is
not:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Service Information in the Server Utilities tree in the left
panel. The TSM Services tab appears in the right
panel.
- Check to see if the TSM device driver is running. If it is stopped,
right click TSM Device Driver. A pop-up menu appears.
- Click Start in the pop-up menu.
- Obtain the library and drive information for the shared library
device:
- Double click the
TSM Server Utilities icon on the desktop. The TSM
Server Utilities window opens.
- Click
Device Configuration in the TSM Server Utilities tree (left
pane). The Device Configuration tab appears in the right
pane.
- Click Refresh in the right pane. Updated library and
device information appears.
- Define the shared library, SANGROUP.
Note: | Ensure that the library name agrees with the server library name.
|
define library sangroup libtype=shared primarylibmanager=libmaster
- Define the drives to the library by using the same names as the drives on
the library manager. Element addresses are not required for shared
libraries when defining drives on the library client.
define drive sangroup drivea device=mt0.1.0.3
define drive sangroup driveb device=mt0.1.0.3
Note: | Administrators do not have to specify all of the drives in the shared library
device.
|
- Define at least one device class. Use a low mount retention time
(1-2 minutes) and mount wait time for shared library devices.
Set the mount wait times to different values for each server.
define devclass tape devtype=dlt mountretention=1 mountwait=10 library=sangroup
- Define the storage pool to use for database backups for the shared
library.
define stgpool backtape tape description='storage pool for shared sangroup'
maxsize=nolimit collocate=yes maxscratch=50
- Repeat this procedure to define additional servers as library
clients.
