Quantum Scalar 1000, Reference Manual

Page: 38 / 304

22 Configuration
The pool name and assigned cartridge range can be changed later through the Configuration > Logical >
Pool pane. Refer to Pool on page 97. Some DAS and ROBAR clients may also assign cartridges to the
existing pool as well as remove them.
Configure Clean Manager
After the cleaning pools are created and configured, they can be assigned to the appropriate drives for the
drive cleaning operation. Cleaning can be executed either automatically or by client request. This can be
done via the
Configuration > Logical > Drive pane (Drive properties > Cleaning). Refer to Drive on page
104. Specify the correct cleaning time according to the drive type and model. Specify also the cleaning rate
(the number of mounts between cleanings).
Configure Aliasing
Some DAS Clients use old vertions of backup application that cannon correctly recognize the newest
models of media and drives, but must work with such models nevertheless. To fix this issue, Scalar DLC
provides an Aliasing feature.
Using Configuration > Clients > DAS > DAS Client pane > Aliasing (refer to Aliasing on page 143) for
either drive or media (or both) select the alias that the backup application ’understands’ instead of its default
type that the application cannot recognize. Then press
Save button to update the client properties. The
Scalar DLC restart is not required, the client application restart is not required, too.
Reserve Drives and Cartridges
Some DAS clients may reserve the drives and the cartridges which means no one but the client will access
the appropriate resource.
Enter the appropriate values through the Configuration > Clients > DAS > DAS Client pane (Reserved
Drives > (Select Drive) >> Reserve; Reserved Volsers >> Add Volserrange, Remove Volserrange). Refer
to
Drives on page 138 and Reserve or Define Volsers on page 142. Also the customer may perform a
reserve operation by using the special commands ( allocd, allocv ) from the client side.
CAUTION
Sharing a single clean cartridge between two or more cleaning pools is
allowed. Watch however the state of that cartridge with extreme caution.
Note
The cartridges appear in the library during Inventory , but only Admin can mark the
cartridge as cleaning , as described in Mark Cleaning Cartridges on page 21. Also the
‘insert cleaning cartridges to pool’ operation can be executed via DAS by DAS Client.
Note
This feature is optional and used only by some DAS clients.
CAUTION
The drives and cartridges reserved/allocated by Client1 cannot be accessed
by other clients. The allocation must be removed before the other client can
access the reserved resource.
Removing the allocation made by another client is also possible from the
client side by the special command (allocd, allocv) if the client has Supervisor
privileges.
