There are a number of standard commands.

lsvg <name_ofvg> ## Purpose: check for stale disks and partitions
lsvg -l oldDisk
lsvg -l newDisk

lslv -m of logical partitions on either disk

lspv
lqueryvg -g VGID -At

=======
The difficulty is in understanding why you used the -f option, as -f (for force) is optional, There was probably something else wrong as well.

Suntax 1.
replacepv [ -f ] {SourcePhysicalVolume | SourcePhysicalVolumeID} DestinationPhysicalVolume

During replacepv I found the error as Segmentation fault(coredump) and it has generate the core.

Now when I am doing any command for that particulr vg the error is

Segmentation fault(coredump)

and also the migration has not completed sucessfully.

The difficulty here is that under normal circumstances Segmentation faults are caused by applications, not by part of the OS.

In any case, more info is needed, such as:

migrating from what to what; why were you doing a replacepv while doing a migration (an O/S migration, application migration, or was it a move from one system to another (migration in AIX usually means a migration install of AIX); do you have a backup of the volumn group (savevg, or something else).

In any case, without some added info about what you intended to accomplish - more than this is difficult.

Hi,

We were not using the OSmigration, We were using the replacepv -f command ONLINE to move the data from one physical disk to other physical disks. Now there is a corruption ind VGDA. Could you help me to correct the VGDA information.

I guess first of all some report of the current status of the disks, and the logical volumes.

I am copying the whole to the new forums, and shall continue there.

Is this an AIX coredump (didthe system crash)? Or a core file generated? If it's a core file generate, can you tell me what command you were running?
what is the state of the VG?

Thanks
