IBM Tivoli Storage Manager in a Clustered Environment

798 IBM Tivoli Storage Manager in a Clustered Environment

At this point, our team has already installed the Tivoli Storage Manager server

and Tivoli Storage Manager client, which will have been configured for high

availability. We have also configured and verified the communication paths

between the client and server.

After reviewing the readme file and the User’s Guide, we then proceed to fill out

the Configuration Information Worksheet provided in Table 19-2 on page 796.

Using the AIX command smitty installp, we install the filesets for the Tivoli

Storage Manager Storage Agent. This installation is standard, with the agent

being installed on both clients in the default locations.

19.5 Storage agent configuration

We begin our configuration of the LAN-free client by registering our Storage

Agent on TSMSRV03, then set up our definitions locally, and lastly, we configure

our drive paths on the remote Tivoli Storage Manager server.

Locally, we have already defined the VCS Service Group sg_isc_sta_tsmcli,

which hosts the shared disk resource. We will activate the shared disk to

facilitate our setup of the Storage Agent configuration files as follows:

1. First we register our Storage Agent server with the Tivoli Storage Manager

server we will be connecting to, in this case TSMSRV03.

2. Next, we run the /usr/tivoli/tsm/StorageAgent/bin/dsmsta

setstorageserver command to populate the devconfig.txt and dsmsta.opt files,

as shown in Example 19-1.

Example 19-1 The dsmsta setstorageserver command

dsmsta setstorageserver myname=cl_veritas01_sta mypassword=password

myhladdress=9.1.39.77 servername=tsmsrv03 serverpassword=password

hladdress=9.1.39.74 lladdress=1500

3. We then review the results of running this command, which populates the

devconfig.txt file as shown in Example 19-2.

Example 19-2 The devconfig.txt file

SET STANAME CL_VERITAS01_STA

4. Next, we review the results of this update on the dsmsta.opt file. We also see

the configurable parameters we have included, as well as the last line added

by the update just completed, which adds the servername, as shown in

Example 19-3.

5. Then, we add a two stanzas to our /usr/tivoli/tsm/client/ba/bin/dsm.sys file for

the LAN-free connection and a direct connection to the Storage Agent (for

use with the dsmadmc command), as shown in Example 19-4.

6. Now we configure our LAN-free tape paths by using the ISC administration

interface, connecting to TSMSRV03. We start the ISC, then select Tivoli

Storage Manager, then Storage Devices, then the library associated to the

server TSMSRV03.

7. We choose Drive Paths, as seen in Figure 19-1.

8. We select Add Path and click Go, as seen in Figure 19-2.

9. Then, we fill out the next panel with the local special device name, and select

the corresponding device which has been defined on TSMSRV03, as seen in

Figure 19-3.
