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 155 and Reserve or Define Volsers on page 158. Also the customer may perform a
reserve operation by using the special commands ( allocd, allocv ) from the client side.
Define Drives and Cartridges
Some DAS clients may define the drives they will use and the cartridges they may access.
Define the appropriate values through the Configuration > Clients > DAS > DAS Client pane (Defined
Drives >> Specify >> Save changes; Defined Volsers >> Add Volserrange, Remove Volserrange). Refer to
Define Drives on page 156 and Reserve or Define Volsers on page 158. Also the customer may perform a
temporary define operation by using the special command ( scop2 ) from the client side.
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.
Note
This feature is optional and used only by some DAS clients.
Note
Using the Management GUI Admin can execute any operation whether the used
medium and/or drive is reserved or not.
Also Admin can remove the allocation, either through Configuration > Clients > DAS
> DAS Client pane (Reserved Drives >> Specify >> Save changes; Reserved Volsers
>> Add Volserrange, Remove Volserrange), or through Configuration > Logical >
Drive (Drive properties > Owner >> None >> Save changes) and Configuration >
Logical > Cartridge (Cartridge properties > Owner >> None >> Save changes).
CAUTION
The drives and cartridges defined by Client1 are in common use, but the
Client1 itself can access only the
defined drives and media. ‘None defined’
means the Client1 can use all drives and all media in the library it is assigned
to.
Note
This feature is optional and used only by some DAS clients.
