Install or upgrade to the latest level of the client
software and the TSM API software. Then install the storage agent
software.
- Check that the Tivoli Data Protection client system meets the
prerequisites for client software. See the applicable Tivoli Data
Protection documentation. Install the client software if it is not
already installed on the system, or upgrade the software to the latest level
as necessary.
- Ensure that the client connects with a server that supports the Managed
System for SAN feature. The client options file (dsm.opt) must
include the TCP/IP address of the server. For example:
commmethod tcpip
tcpserveraddress garden.tucson.tivoli.com
tcpport 1500
- Update the API software to the latest level by following the procedure
described below.
Note: | Ensure that the Tivoli Data Protection client is already installed.
|
- Download the TSM Version 4.1 for the Windows backup-archive client
and the associated BAT file from
http://www.tivoli.com/support/storage_mgr/tivolimain.html
.
- Run the BAT file to unzip the files, and follow the directions to begin
the installation procedure.
- From the Setup Type window, click Custom.
- From the Select Components window, select Client
Files and click Change.
- Select API Client Runtime Files and deselect the other
components.
- Ensure that you specify as the installation directory for the API the same
directory as that in which the existing API resides.
-
Manually set the option in the client options file (dsm.opt) to enable
the LAN-free data transfer. You cannot set this option through the
graphical user interface (GUI). Add the following line to the
dsm.opt file:
enablelanfree yes
The enablelanfree option specifies whether you want the client to
use SAN-attached devices during backup, restore, archive and retrieve
processing, if the path to the SAN devices is available.
For information about the dsm.opt file, refer to the Tivoli
Storage Manager Installing the Clients.
On the same system as the client, install the storage agent.
- Gather the following information:
- Storage agent: Name and password for the storage
agent. The name and password must be the same as the name and password
that is used to define the storage agent as a server to the TSM server.
For example:
- Name: IRIS
- Password: jonquil
- TSM server: Information about the TSM server with which
the storage agent will communicate. This is the same TSM server with
which the client communicates. For example:
- Name: GARDEN
- Password: botanical
- TCP/IP address: garden.tucson.tivoli.com
- TCP/IP port: 1500
- Insert the Managed System for SAN CD-ROM in the drive of the client
system. Follow instructions on the screen to install the storage
agent. The results of the installation are:
- The software is installed
- The options file for the storage agent (dsmsta.opt) is created in
the path c:\program files\tivoli\tsm\storageagent
- The TSM device driver is installed for use by the storage agent, but needs
to be started and set to start at boot (seeStart the Device Driver for details)
- Ensure that a device configuration file exists and that the matching
DEVCONFIG option is in the dsmsta.opt file. For example, for a
device configuration file named devconfig located
c:\program files\tivoli\tsm\storageagent, edit the
dsmsta.opt file and enter the following line:
DEVCONFIG devconfig
- Use the information that you collected in step 1 to issue the DSMSTA SETSTORAGESERVER command. For
example:
dsmsta setstorageserver myname=iris mypassword=jonquil
servername=garden serverpassword=botanical
hladdress=garden.tucson.tivoli.com lladdress=1500
See Set Installation Data for the Storage Agent: DSMSTA SETSTORAGESERVER for the details on the command parameters.
The command generates the following lines in the device configuration file
for the storage agent:
+--------------------------------------------------------------------------------+
|SET STANAME iris |
|SET STAPASSWORD xxxxxxx |
|DEFINE SERVER garden serverpassword=xxxxxxxxxxx |
| HLADDRESS=garden.tucson.tivoli.com LLADDRESS=1500 |
| |
+--------------------------------------------------------------------------------+
The passwords (shown here as xxxxxxxx) are encrypted in the
file.
The command also generates the following line in the dsmsta.opt
file:
+--------------------------------------------------------------------------------+
|SERVERNAME garden |
+--------------------------------------------------------------------------------+
See The Storage Agent Options File and The Device Configuration File for the Storage Agent for details on these files.
The following is an overview of the steps that you need
to do on the TSM server. For details, see Administrator's
Guide. On the server, you will do the following:
- Configure the SAN drives. This involves the following steps:
- Define a shared SCSI library
- Define drives that are associated with the library
- Define the device class
- Define the storage pool
- For each client for which you want to enable SAN data transfer, define
that client's storage agent as if it was a server. You must use
the same name and password that you set for the storage agent when you
installed it on the client system. For example:
define server iris serverpassword=jonquil
hladdress=sanclient.tucson.tivoli.com lladdress=1500
- Modify policy for the client so that the storage agent acting on behalf of
the client uses the drives on the SAN. The client must use a management
class that has copy groups with a destination storage pool that is associated
with the library on the SAN for which you have mapped drives for the
client. See Administrator's Guide for details on changing policy for clients that can use SAN
drives. For example, do the following:
- Create a policy domain for clients that will use the SAN devices for
direct data transfer.
- Create a policy set in that domain.
- In the default management class for that policy set, modify the copy
groups: Set the destination storage pool to the storage pool associated
with the SAN drives that you configured and mapped for the client.
Note: | If you decide not to use the default management class for the SAN drives, you
will need to create a new management class. Clients that want to use
the SAN drives then need to update the include-exclude list to specify the new
management class. See Tivoli Storage Manager Installing the
Clients for details on the include-exclude list.
|
- Activate the policy set.
- Register or update the clients so that they are in the new policy
domain.
See Administrator's Reference for details on the commands.
To review the expected results of the steps that you have just completed,
