How IAP con

ﬁgures TSM

IAP’s impl

ementation of TSM backup uses only a primary storage pool. No copy storage pools a re

created. A

ll volumes in the primary storage pool must remain in the library at all times. A full backup is

taken whe

n backups are ﬁrst initialized. After that, only incremental backups are taken.

Ifatapevolumebecomescorruptedorhasdataloss,backupsmustbere-initialized.Thismeansthatall

existing data on tape is removed and a full backup is taken for all smart cell groups in the IAP.

The IAP backup server is initially conﬁgured with the script /usr/local/tsmBackup/configTiv

init from the PCC machine.

This scri

pt uses the TSM administrative command line interface to connect to TSM, and sends TSM

commands that cre ate the TSM o bjects and conﬁgurations that are necessary for backing up IAP data.

The TSM objects that are created are always preceded with an appropriate preﬁxtomakeiteasierto

remember and recognize the object names. The association of preﬁxesandobjectsisasfollows:

• LIB: Lib

raries

• DC: Device Classes

• DR: Drives

• SP: Sto

rage P ools

The det

ails of the conﬁgTiv script are not required for day-to-day operation, but might be useful for TSM

administrators who are interested in customizing their systems.

The process of setting up the initial T iv oli conﬁguration is divided into three phases:

1. Establishing general backup server settings.

•Thede

fault password expiration time is the maximum available (27 years).

• The password for the administrator is set to never expire.

• To prevent clients from creating unexpected nodes, the client registration is set to closed. Only

the ad

ministrator can register client nodes. (See the Tivoli Administra tion Guide on “Closed
