Balanceo Servidores TSM o Recuperacion BBDD

TSM en cluster

Cambios para GestionTsm –> GestionTsm-backup:

1. Paramos el servidor en el GestionTsm:

/etc/init.d/tsmserv stop

2. Cambio de IP’s:

Sobre el GestionTsm:

ifconfig eth0 23.23.23.x netmask 255.255.255.0 up

ifconfig bond1 10.228.140.x netmask 255.255.255.224 up

Sobre el GestionTsm-backup:

ifconfig eth0 10.228.140.x netmask 255.255.255.224 up

ifconfig eth1 23.23.23.x netmask 255.255.255.0 up

3.      Montaje de fs:

4.      Ejecutamos autoconf sobre el GestionTsm-backup:

/opt/tivoli/tsm/devices/bin/autoconf

5.      Finalmente, copiamos los archivos de configuración en el GestionTsm-backup:

Desde GestionTsm:

scp /opt/tivoli/tsm/server/bin/dsmserv.dsk 10.228.140.x:/opt/tivoli/tsm/server/bin/dsmserv.dsk

scp /opt/tivoli/tsm/server/bin/dsmserv.opt 10.228.140.x:/opt/tivoli/tsm/server/bin/dsmserv.opt

Desde GestionTsm-backup

cp /vtape32/volhist_5 /opt/tivoli/tsm/server/bin/volhist

cp /vtape32/devconfig_5 /opt/tivoli/tsm/server/bin/devconfig

6.      Arrancamos el tsm en el servidor GestionTsm-backup:

/etc/init.d/tsmserv start

7.      Desactivamos los fs en el GestionTsm:

lvchange -an /dev/vtape4vg/vt31lv

lvchange -an /dev/vtape4vg/vt32lv

lvchange -an /dev/vtape4vg/vt33lv

lvchange -an /dev/vtape4vg/vt34lv

Restaurar una DDBB de TSM

Si al levantar el tsm falla:

/etc/init.d/tsmserv start

La forma de levantarlo para ver los log de error es

/opt/tivoli/tsm/server/bin/dsmserv

Después de ver los log si hay que restaurar la BBDD primero busco que cinta es donde esta la BBDD:

/opt/tivoli/tsm/server/bin/dsmserv restore db todate=TODAY preview=yes

Pedimos la cinta a operación y modificamos el archivo 

/opt/tivoli/tsm/server/bin/devconfig

En windows es devconfig.out

Poniendo una entrada 

/* LIBRARYINVENTORY SCSI SL500 A00004 1005 101*/

Donde este la cinta del backup modificando la cinta y el 1005

Y ahora restauramos la BBDD

/opt/tivoli/tsm/server/bin/dsmserv restore db todate=TODAY preview=no

Y levantamos

/etc/init.d/tsmserv start
