How to migrate the data with vmvx

[Thomas_Schulz_3]

Hello.

Ich have a Solaris9 server with an 3.x VXVM installation. Now we need to migrate all the data from an EMC CX400 to a DMX-4.

The implementation from the LUN in the OS and in vxvm is not the problem.

My problem is the migration from the old LUN to the new LUN. I have no idea which vxvm commands i need.

Please help me :)

you can use the mirroring function. these commands will get you started:

# vxdisksetup -i  lun1 ( repeat for all luns/disk)

# vxdg -g <diskgroup> adddisk newdisk1=lun1  newdisk2=lun2.

# vxassist -g <diskgroup> -b  mirror <name of volume to be mirroed>  lun1 lun2 (specify the  lun(s) to use)
where -b is optional if you want to run the mirroring in the backgroud

# vxplex -g <diskgroup> dis old_plex_name

# df  -kl ( make sure all data is active.. havent removed the wrong plex)

# vxedit -g <diskgroup> -rf rm old_plex_name

# vxdisk -o alldgs list

Onw more question.

Is there a "move" command availiable ?

Hello,

you can move subdisks only, but before you have to create them on your DMX... in your case mirroring is the best way !

maybe some scripts...

check out vxevac which is a move like operation, not sure about how you could recover if needed.
