a. Define a shared ACSLS, SCSI, or 3494 library using the SHARED=YES
option.
b. Define paths to the library using the DEFINE PATH command on the
server.
c. Define drives that are associated with the library.
d. Define paths to the drives using the DEFINE PATH command on the server.
e. Define the device class.
f. Define the storage pool.
When you are connecting the storage agent to the library client, complete Step
a through Step e above on the library manager, and then complete the
following steps on the library client:
a. Define a shared ACSLS, SCSI, or 3494 library using a library type of shared
(LIBTYPE=SHARED).
b. Define the device class.
c. Define the storage pool.
Disk Device
Configure server-to-server communication and define a device class of
DEVTYPE=FILE and SHARED=YES. Tivoli Storage Manager automatically
defines a new FILE library and also defines drives corresponding to the mount
limit for the FILE device class. The FILE library name is the same as the device
class name. Each drive uses the library name with a numeric suffix. If the
mount limit is changed, the number of drives also changes.
Note:
Because each session gets exclusive access to a file volume, the mount
limit should correspond to the number of expected concurrent backups.
4. Define a copy group with its destination being the LAN-free capable storage
pool (created in Step 3). For example:
define copygroup sandirect sandirectpolicy sandirectdefmft
type=backup destination=<storage pool name from Step 3>
Then activate the policy set. For example:
activate policyset sandirect sandirectpolicy
Notes:
a. See the Administrator’s Guide for details about changing policy for clients
that can use SAN drives. For details about the commands, see the
Administrator’s Reference.
b. 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 need to use an include statement to bind their files to this
new management class. See the Backup-Archive Clients Installation and User’s
Guide for details about the include-exclude list.
c. Note that with a hierarchical storage management (HSM) client configured
for LAN-free data movement, the management class (not the copy group) is
set to a LAN-free capable storage pool.
5. If the node has already been registered and configured for LAN-free backups,
issue the following command to confirm that the node settings are correct:
query node node_name format=detailed
You can issue the UPDATE NODE command to adjust settings for your node. If
the node has not been registered and configured for LAN-free backups, register
