migrate to another SAN storage

[chinchillaking]

Hi All,

As I know, migrate could be use vgexport and vgimport to another SAN storage LUN, is OK for Oracle ASM disk native multipath with PVG? One more question, the vg01 did not display in /etc/lvmtab.

>> migrate could be use vgexport and vgimport to another SAN storage LUN

By use of vgexport/vgimport the data remains where it is, but you export/import the VG definition from/to the server.

If you want to migrate to another storage, consider

- LVM mirror

- backup/restore

- SAN replication tools

[Torsten.]

Since vg01 is LVM version 2.x, it is not in lvmtab, but in /etc/lvmtab_p
