In this project I’m trying to migrate data from EMC to HDS from the
operating system side. Once the migrating is complete, remove EMC drive
from the system and totally depend upon Hitachi.
Here are the steps that I took for this process.
1) Get new Hitachi LUNs from your SAN Admin.
2) Verify that from format command. ( You might even need to reboot the server)
3) Install required ASL for Hitachi support in VxDMP.
4) Verify all the paths are seen from Veritas Dynamic Multipathing.
5) Label new drives with format utility.
6) Assign new drive name and group.(Bring in Veritas control)
7) Mirror Veritas Volume using VxVM commands.
8 )Break the mirror plex of EMC drives.
9) Remove EMC drives from Veritas control.
10) As your SAN admin to remove EMC drives from the server.
This is what it looks like before getting new Hitachi drives

Once all the mirroring is complete use the following command to break plex from
EMC drive (Be very careful while breaking the mirror)
In our case we are breaking u01-01, u02-01, u03-01, u04-01 and u05-01
Disassociate plex
#vxplex -g vgora01 dis u01-01
#vxplex -g vgora01 dis u02-01
#vxplex -g vgora01 dis u03-01
#vxplex -g vgora01 dis u04-01
#vxplex -g vgora01 dis u05-01

operating system side. Once the migrating is complete, remove EMC drive
from the system and totally depend upon Hitachi.
Here are the steps that I took for this process.
1) Get new Hitachi LUNs from your SAN Admin.
2) Verify that from format command. ( You might even need to reboot the server)
3) Install required ASL for Hitachi support in VxDMP.
4) Verify all the paths are seen from Veritas Dynamic Multipathing.
5) Label new drives with format utility.
6) Assign new drive name and group.(Bring in Veritas control)
7) Mirror Veritas Volume using VxVM commands.
8 )Break the mirror plex of EMC drives.
9) Remove EMC drives from Veritas control.
10) As your SAN admin to remove EMC drives from the server.
This is what it looks like before getting new Hitachi drives

Once all the mirroring is complete use the following command to break plex from
EMC drive (Be very careful while breaking the mirror)
In our case we are breaking u01-01, u02-01, u03-01, u04-01 and u05-01
Disassociate plex
