Redhat 4 host based migration
Hi,




I need to migrate using Redhat 4 as host based migration,EMC Clariion to VNX.

Please what are the best ways to perform online migration,with users working on the box?The file system is ext3 and the source logical voulumes are raid 1.


- adding the 3rd LUN(from VNX) to the current raid1 logical volume
- using rsync between 2 boxes with redhat 4,one box has raid 1 logical volume and the other one has new LUN(VNX).NFS exports the file system on the LUN in VNX and mount this on the other box.Then tar,cpio.
- pvmove,only if I do not need the data in old raid 1 logical volume.
- split raid1 into 2 submirrors and mirror one of those submirrors with LUN in VNX.



tnx a lot,
marius

lvremove

LVREMOVE(8)						      System Manager's Manual						       LVREMOVE(8)

NAME

       lvremove - remove a logical volume

SYNOPSIS

       lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...]

DESCRIPTION

       lvremove  removes  one  or  more  logical  volumes.   Confirmation will be requested before deactivating any active logical volume prior to
       removal.  Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted  filesystem).   Removing	an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS

       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

EXAMPLES

       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

	    lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

	    lvremove vg00
