SANDISCOVERY

Specifies whether the Tivoli Storage Manager SAN discovery function is

enabled. When set to ON, the storage agent will perform SAN discovery in

the following instances:

v During storage agent initialization

v When the device path has been changed and there is a conflict between

the device serial number and the device path provided by the server

Using SAN discovery, the storage agent can automatically correct the

device’s special file name if it has been changed. If the HBA used by the

storage agent does not support SAN device mapping, you should set the

SANDISCOVERY option to OFF.

For information about Tivoli Storage Manager supported HBAs for SAN

device mapping, see www.ibm.com/software/sysmgmt/products/

support/IBMTivoliStorageManager.html

The storage agent does not require persistent binding with the SAN

discovery function enabled.

 

STAMaxpooledsessions number

 

Specifies the number of individual sessions that are allowed to start and

 

stop between the storage agent and the Tivoli Storage Manager server. The

 

range of values is 0 - 150, with a default of 25. Each session is governed by

 

the IDLETIMEOUT option and is stopped when the timeout value is

 

exceeded. If the storage agent needs more sessions than specified,

 

additional sessions are allowed. Although the default value is typically

 

sufficient, setting this option with a low number can adversely affect

 

performance. Be aware that if the storage agent has multiple client

 

sessions, increasing the value of this option will help support these

 

sessions.

 

TCPADMINPORT number

 

Specifies the port number on which the server TCP/IP communication

 

driver is to wait for requests for sessions other than client sessions. This

 

includes administrative sessions, server-to-server sessions, SNMP subagent

 

sessions, storage agent sessions, library client sessions, managed server

 

sessions, and event server sessions. The default is the value of TCPPORT.

 

Using different port numbers for the options TCPPORT and

 

TCPADMINPORT enables you to create one set of firewall rules for client

 

sessions and another set for the other session types listed above. By using

 

the SESSIONINITIATION parameter of REGISTER and UPDATE NODE,

 

you can close the port specified by TCPPORT at the firewall, and specify

 

nodes whose scheduled sessions will be started from the server. If the two

 

port numbers are different, separate threads will be used to service client

 

sessions and the session types. If you allow the two options to use the

 

same port number (by default or by explicitly setting them to the same

 

port number), a single server thread will be used to service all session

 

requests. Client sessions which attempt to use the port specified by

 

TCPADMINPORT will be terminated (if TCPPORT and TCPADMINPORT

 

specify different ports). Administrative sessions are allowed on either port,

 

(unless the ADMINONCLIENTPORT option is set to NO) but by default

 

will use the port specified by TCPADMINPORT.

 

THROUGHPUTDatathreshold kilobytes_per_second

 

Specifies the throughput that client sessions must achieve to prevent

 

cancellation after THROUGHPUTTimethreshold minutes have elapsed. The
