    Hi,

    First you need to add the new disk into veritas diskgroup, currently you have only 1 disk in diskgroup & hence you run above mentioned command now, it will fail saying no such disk found.

    If emc1_01ba is the disk from new array, you can add in to existing dg using below command

    # vxdisksetup -i emc1_01ba    (assuming that new disk was not initialized in veritas)

    # vxdg -g klcdsctcrsyb019g1_sybasedg adddisk klcdsctcrsyb019g1_sybasedg02 = emc1_01ba

    With this command successful, once you run the vxprint command as you ran above, you should see 2 "dm" records in diskgroup i.e 2 disks in diskgroups.

    Now you can run the mirror command you mentioned in your post & it will succeed

Hi Karim

First of all, there is only one disk in the DG. You need to add disks from the other disk array which you want to migrate data to.

# vxdisksetup -i emc1_01ba 

# vxdg -g klcdsctcrsyb019g1_sybasedg emc1_01ba

Then you can use the vxassist to mirror data to it:

# vxassist -g klcdsctcrsyb019g1_sybasedg mirror sybase klcdsctcrsyb019g1_sybasedg02

NOTE: Here is just an example of one volume "sybase". You need to run this command for each volume you want to migrate. vxasssit will not mirror other volumes in one command.

And after all volumes are mirrored, splite and remove disks from the old array from DG.
