IBM Tivoli Storage Manager in a Clustered Environment

12.6 Persistent binding of tape devices

Device configuration on SAN-attached devices is made simpler with the Tivoli

Storage Manager SAN Device Mapping function (SDM). SDM uses the SNIA

(Storage Networking Industry Association) Host Bus Adapter (HBA) API to

perform SAN discovery. The device serial number, manufacturer, and worldwide

name are initially recorded for each storage device. When the device

configuration changes, Tivoli Storage Manager can automatically update the

device path information without the need for device persistent binding.

In our lab environment we use a IBM TotalStorage 3582 Tape Library with two

LTO2 tape drives, each of them with one FC port. The first tape drives also acts

as medium changer device. As we depend on the path to the first tape drive

anyway, we do not activate the SDM function.

You can find a list of supported HBA driver versions for SDM at:

12.7 Installation of Tivoli System Automation

Before we start the installation and configuration of Tivoli System Automation for

Multiplatforms, we must set the management scope for RSCT for all users of

Tivoli System Automation for Multiplatforms on all nodes. We set the variable

permanently by setting it in the profile.

export CT_MANAGEMENT_SCOPE=2

We downloaded the Tivoli System Automation for Multiplatforms tar file from the

Internet, so we extract the file, using the following command:

tar -xvf <tar file>

Now we change to the appropriate directory for our platform:

cd SAM12/i386

We install the product with the installSAM script as shown in Example 12-11.
