REQ  command. For more information, see TS7700 Library Request Command V5.0 , WP101091. 

DS QLIB Use the DEVICE SERVICES QUERY LIBRARY  command to display library and device-related information for the composite and distributed libraries. 

A subtle difference exists between the DS QLIB  and LI Commands, but it is important to understand. The DS QLIB  command can return different data, depending on which host it is entered. An LI command returns the same data without regard to the host if both hosts have full accessibility. 

## Automation handling and messages 

The TS7700 provides a method within the MI to customize if and how alerts are surfaced by the TS7700. Each can be independently modified in the following way: 

GLYPH<SM590000> Customized severity 

GLYPH<SM590000> Whether the notification is surfaced 

GLYPH<SM590000> To which notification channels (Host, SNMP, RSYSLOG server) the message is sent 

GLYPH<SM590000> Sending more custom text information to the notification channels to help with automation 

The changes to the event notification settings are grid wide and persistent if new microcode levels are installed. 

In addition, you can back up these settings and restore them independently on other grids to improve the ease of managing maintenance of a multi-grid environment. 

For information about content-based retrieval (CBR xxxx ) messages, see hTS7700 Series Operator Informational Messages , WP101689. 

## Tools 

Many helpful tools are available for the TS7700. For more information, see Chapter 9, “Configuring and operating the IBM TS7700” on page 339. 

## Remote System Log Processing Support 

Because security is becoming a critical aspect for most customers, all events and messages can be sent to one or two different RSYSLOG servers. Remote System Log Processing Support (RSYSLOG) is an open standard utility that uses TCP for the message transport. 

An MI interface is provided to configure a TCP port and an IP address to an RSYSLOG server to send the events from TS7700. 

## Call Home support 

The Call Home function automatically generates a service alert when a problem is detected within the subsystem, such as a problem in the following components: 

GLYPH<SM590000> Inside the TS7700 components 

GLYPH<SM590000> In the associated TS3500 or TS4500 library and tape drives (if present) 

GLYPH<SM590000> In the cache disk subsystem 

Status information is transmitted to the IBM Support Center for problem evaluation. An IBM Service Support Representative (IBM SSR) can be dispatched to the installation site if maintenance is required. Call Home is part of the service strategy that is adopted in the TS7700 family. It is also used in a broad range of tape products, including VTS models and tape controllers.
