SAN Migration - using veritas volume manager

Plan,
Work with storage team to present the new luns on both hosts. Mirror the luns (volume) on source server and break the mirror. Export the diskgroup and import the disk group to the new host. Star the volume on new host, everything should be fine.
Make sure proper backup is on place.
Work with network team to Push new DNS updates and remove the entry for old host on the dns.
Work with database/application folks to bring the database and application up.
Validate the database(s) are operational and ready to use
wait for at least 1 month to make sure everything is operational.
Issue retirement request to retirement team to retire the old server.

Create a volume with a plex called plex2
# vxmake -g baddg vol vol2 plex=plex2

Start a volume
Next, we must start the new volume
# vxvol -g SAMSUN09dg start vol2

Then use vxplex ‘att’ to attach the plex to the original volume. The plex will be synchronised with the plex(es) already

attached to
the volume.
# vxplex -g diskgroup att plex_name
==============================

mirror a volume

Break a mirror

In the following steps we are going to disassociate the plexes from the parent volume using vxplex ‘dis’. VxVM also has a vxplex
‘det’ which is to detatch a plex. Confusingly, detatching a plex with vxplex ‘det’, stops writes to the plex, but the plex stays
associated with the parent volume

The first step is to detach one of the plexes and break its link to the remaining plex(es) (i.e. dissociate). We’ll

dissociate
‘plex2′

# vxplex -g baddg dis plex2

========================
 Disassociate the mirror plex:

# vxplex -g oradg dis oravol-02


attach back mirror plex to the volumedisk:

# vxplex -g oradg att oravol oravol-02


vxplex command to remove all the plexes of the volumes
# vxplex -o rm dis oravol-02 FS_VOL_vol-02 Next_VOL-02
