TSM 6.2 Implementation and Administration Training Day 5


Finally, the last day comes. Happy Friday Smile

Unit 11: Automating operations

Lesson 1: Scheduling options

Two types of scheduling: Client scheduling/ Administrative scheduling on server

The central scheduler supports two modes of client scheduling:
– Client polling
– Server prompted

Scheduling options

Lesson 2: Client scheduling

Backup-restore and archive-retrieve
– Client operating system command script
– One time scheduled commands

Traditional scheduler services

dsmc shed (requires higher use of system resources when idle)

Client acceptor daemon services

TSM Client Acceptor Daemon service (CAD) is a web client process, which uses an HTTP service that serves the web client Java applet to the web browsers.

Central scheduling mode: Client polling

client periodically queries or polls the server for a scheduled operations and the date and time that operation is to start

Central scheduling mode: Server prompt

client queries the operation after been notified by the server

Scheduling mode

SET SCHEDModes ANY|Polling|Prompted

Additional client scheduling options

Additional client polling options

QUERYSCHEDPERIOD

Additional server prompted options

TCPCLIENTADDRESS
TCPCLIENTPORT

Preschedule and postschedule processing

PREscheduleCMD or PRENscheduleCMD (does not wait for client OS commands to finish)
POSTscheduleCMD or POSTNscheduleCMD (does not wait for client OS commands to finish)

Consistent client return codes

0: completed successfully
4: completed successfully, except for one or more skipped files
8: completed with one or more warning messages issued
12: operation failed with one or more error messages issued

Example of randomizing

Randomizing spreads out the start up time to balance the load on the server as well as the load on the networks (max is 50%)

Defining schedules

define schedule
define association

parameters for defining schedules

Enhanced scheduling

also known as calendar-based

Relative date and time

relative date by default is Today
relative time by default is Now

Copy SCHEDULE command

copy schedule domain1 labsys domain2 labsysnew

Define association command

define association domain_name schedule_name node_name

One-time scheduled client commands

define clientaction

Unwanted schedule actions

SRVPREPOSTSCHEDDISABLED
SRVPREPOSTNSCHEDDIABLED
SCHEDRESTRETRDISABLED

Lesson 3: Administrative tasks

Automating administrative tasks

– Migration
– Reclamation
– Expiration
– Storage pool backup
– Database backup

define schedule backup_archivepool type=adminsitrative cmd=”backup stgpool archivepool recoverypool” active=yes startime=18:00 period=3

Additional functions to schedule

Export-import
– Changing device class mount point limits
– Volume history maintenance
– All administrative command except query actlog

Unit 12: Monitoring and event logging

Lesson 1: Client event messages

Monitoring and logging events

client messages (events) are logged on the TSM server

Client event formatting

A N [R S E] # # # # [I W E S]

Lesson 2: Working with events and logs

Event receiving

Event viewer/ TSM console/ Activity log/ …

Begin eventlogging

begin eventlogging all/ console/ actlog/ eventserver/ …

enable event console,file

disable event

The QUERY ENABLE command

query enable console node=DBSERVER1

query eventrules

end eventlogging
