UPGRADE de SDDPCM en VIO SERVER

[Tomamos como punto de partida un entorno con Dual-Vios]

1-. Generamos un perfil "clon" del actual, en nuestros Vio server, en este perfil hemos de prescindir de los adaptadores de fibra.

2-. Apagamos la particion, Vio Server.

3-. Arrancamos la parcición el nuevo perfil, "clon_sddpcm_upgrade".

4-. Eliminamos los dispositivos, discos, que se presentaban por fibra.

[si estamos presentando discos desde una cabina DS8000].

# lsdev -Cc disk |grep 2105 |while read col1 col2 col3 col4
do
echo $col1
rmdev -dl $col1
done

# lsdev -Cc disk |grep 2107 |while read col1 col2 col3 col4
do
echo $col1
rmdev -dl $col1
done

5-. Paramos el servicio de SDDPCM:

#stopsrc -s pcmsrv

6-. Eliminamos el paquete de SDDPCM

7-. Instalamos el nuevo paquete SDDPCM

8-. Apagamos la partición, y arrancamos con el perfil original, Con Fibra.

NOTA: Se recomiendo un exaustivo Backup.
