root@ # umount /resp_tmp
root@ # umount /RMANMX
root@ # umount /g5mxcs
root@ # umount /g5mx_adm
root@ # umount /g5mxtx
root@ # umount /oas_cluster

3. DEPORTAR EL DISKGROUP

root@ # vxdg deport g5mx_dg
VERIFICA EL STATUS DEL DISKGROUP
root@ # vxdisk -o alldgs list | grep g5mx_dg
emcpower0s2 auto:cdsdisk - (g5mx_dg) online

4. REALIZAR ESTABLISH

root@ # ./establish
Contenido del script establish: /opt/emc/SYMCLI/V6.4.3/bin/symmir -g g5db02 -full establish

VERIFICAR AVANCE DE LA SINCRONIZACION COLUMNA State.

root@ # symmir -g g5db02 query

VERIFICAR TERMINO DE LA SINCRONIZACION DE LOS DISPOSITIVOS HAYAN TERMINADO SIN PROBLEMAS

root@ # symmir -g g5db02 query

AL TERMINO DE LA SINCRONIZACION CAMBIAR EL MODO DE LA BDD DE NORMAL A BEGIN BACKUP CONFIRMAR CON DATABASE ADMINISTRATOR


5. EJECUTAR SPLIT
root@ # ./split

Contenido del script split: /opt/emc/SYMCLI/V6.4.3/bin/symmir -g g5db02 -instant split

VERIFICAR STATUS DEL SPLIT HAYA TERMINADO COLUMNA State DEBE MOSTRAR como Split

AL TERMINO DEL SPLIT CAMBIAR EL MODO DE LA BDD A NORMAL CONFIRMAR CON EL DATABASE ADMINISTRATOR

VERIFICAR STATUS DEL DISKGROUP

root@ # vxdisk -o alldgs list | grep g5mx_dg
DEVICE TYPE DISK GROUP STATUS
emcpower0s2 auto:cdsdisk - (g5mx_dg) online
emcpower1s2 auto:cdsdisk - (g5mx_dg) online
emcpower2s2 auto:cdsdisk - (g5mx_dg) online
emcpower4s2 auto:cdsdisk - (g5mx_dg) online
root@ #


6. PARA REINICIAR EL DISKGROUP, IMPORTAR EL DISKGROUP, FSCK Y MONTAR SUS FILESYSTEMS

root@ # vxdctl enable
root@ # vxdg import g5mx_dg

En caso de que falle el import y se este seguro de que no este importado el diskgroup en otro Server usar la opcion de Clear Host ID: root@ # vxdg -C import g5mx_dg

root@mxg5db02 # vxdisk -o alldgs list | grep g5mx_dg
emcpower0s2 auto:cdsdisk g5mx_dg03 g5mx_dg online
emcpower1s2 auto:cdsdisk g5mx_dg01 g5mx_dg online nohotuse
emcpower2s2 auto:cdsdisk g5mx_dg02 g5mx_dg online
emcpower4s2 auto:cdsdisk g5mx_dg04 g5mx_dg online
root@ #

root@ # fsck -y /dev/vx/rdsk/g5mx_dg/resp_tmp
root@ # fsck -y /dev/vx/rdsk/g5mx_dg/rmanmx
root@ # fsck -y /dev/vx/rdsk/g5mx_dg/g5mxcs
root@ # fsck -y /dev/vx/rdsk/g5mx_dg/g5mx_adm
root@ # fsck -y /dev/vx/rdsk/g5mx_dg/g5mxtx
root@ # fsck -y /dev/vx/rdsk/g5mx_dg/oas_cluster

root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/resp_tmp /resp_tmp
root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/rmanmx /RMANMX
root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/g5mxcs /g5mxcs
root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/g5mx_adm /g5mx_adm
root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/g5mxtx /g5mxtx
root@ # mount -F vxfs /dev/vx/dsk/g5mx_dg/oas_cluster /oas_cluster

Listo! Ha quedado terminado nuestro BCVs.

Random TIPS

CLEANUP DOS FILES
If you deal with DOS files and the "^M" character always appears at the end of the line, here are two ways to get rid of them.
If you edit the DOS text file with the "vi" editor in UNIX, use the following from the "vi" command line:
:%s/^V^M//g
From a Unix shell use the command:
% sed 's/^V^M//g' foo > foo.new
NOTE: ^V is control V and ^M is control M or Enter
