Configuring Your Library
Working With Data Path Conditioning
When I/O blades are installed, administrators can configure data path conditioning, an automatic means of verifying,
monitoring, and protecting data path integrity between FC I/O blades and FC tape drives. Data path conditioning allows you
to proactively detect and resolve data path problems before they affect backup, restore, and other data transfer operations.
The I/O blade does not manage data path conditioning along the path between the host and the I/O blade. It does manage
data path conditioning along the path between itself and the FC tape drives. Data path monitoring automatically occurs at
regular, configurable intervals. The I/O blade generates a RAS ticket if the monitoring tests fail for two intervals.
To configure data path conditioning, set the following parameters for the selected I/O blade:
•
The level at which the data path is monitored between an I/O blade and the FC tape drives connected to it. The two
levels are as follows:
•
Interface Test — performs tests to verify that FC controllers on I/O blades are responsive to commands. This is
the default level.
•
Device Datapath Test — performs tests at the interface Test level and also performs a device inquiry on each
target device.
•
Test Interval — the time interval between monitoring checks. You can configure the test interval. It can range from 5
to 2,880 minutes (48 hours). If you do not configure the test interval, the default test interval is 60 minutes. If you
disable data path conditioning and then re-enable it in the future, the interval reverts to the default of 60 minutes
regardless of whether you changed the interval previously.
Note:
This operation should not be performed concurrently by multiple administrators logged in from different
locations. You can access the appropriate screens, but you cannot apply changes while another administrator is
performing the same operation.
The paths to open the appropriate screens are as follows:
•
From the Web client, select Setup > I/O Blades > Data Path Conditioning.
From the operator panel, select Setup > I/O Blades > Data Path Conditioning.

Configuring Library Security Settings
Administrators can use the operator panel Security Settings screen to change the following security features:
Network Interface — enables or disables all external access to the library. This setting is enabled by default to allow
•
external access.
SSH Services — enables or disables Secure Shell (SSH) services, such as SSH (port 22), from accessing the library.
•
This setting is enabled by default.
•
ICMP — enables or disables external attempts to discover the library by pinging it (by means of the internet Control
Message Protocol [ICMP] Echo packets). This setting is enabled by default.
•
Remote UI — enables or disables remote access to the library via the Web client (port 80). This setting is enabled by
default.
•
SNMP — enables or disables SNMP traffic to the library (port 161). This setting is enabled by default.
•
SMI-S — enables or disables SMI-S traffic to the library (port 5988). This setting is enabled by default.
Note:
This setting differs from enabling/disabling SMI-S in the Tools > System Settings menu (see
Configuring System
You cannot configure the security settings from the Web client. The path to open the appropriate screen is as follows:
•
From the operator panel, select Tools > Security.
Configuring the Internal Network
Use the Internal Network Configuration screen to configure your library's internal network setting. The default internal
network address is 10.10.10.X
The library's internal network enables communication among library components. While rare, it is possible that the default
