Working With Data Path Conditioning; Configuring Library Security Settings - Quantum Scalar i500 User Manual

Working With Data Path Conditioning

When I/O blades are installed, administrative users 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.
This operation should not be performed concurrently by multiple administrative
Note
users logged in from different locations. You can access the appropriate
screens, but you cannot apply changes while another administrative user 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

Administrative users 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 — enable or disable 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 web client user interface (port 80) to the library. This setting is
enabled by default.
• SNMP — enables or disables SNMP traffic (port 161) across the Ethernet port. This setting is
enabled by default.
• SMI-S — enables or disables SMI-S traffic (port 5988). This setting is enabled by default.
