Multiple ACS robots and ACS library software hosts
NetBackup supports the following configuration:
A NetBackup server is connected to drives in multiple ACS robots.
The robots are controlled from separate ACS library software hosts.
The following figure shows multiple ACS robots that are controlled from multiple ACS library software hosts.
Inventory requests include the volumes that are configured on the ACS library software hosts (Host A for Robot 1 and Host B for Robot 2). The software hosts reside on the robot (ACS 0 for each) that is designated in the Sun StorageTek drive address.
In this example, assume the following about drive 1:
Has an ACS drive address (ACS, LSM, panel, drive) of 0,0,1,1 in the NetBackup device configuration
Is under control of robot number 10 (ACS(10))
If any other robot ACS(10) drives have a different ACS drive address (for example, 1,0,1,0), the configuration is invalid.
NetBackup supports configurations of multiple LSMs in a single ACS robot if a pass-through port exists.
