Operating Systems AIX Logical volume name conflict in two volume group Post 302377808 by dantares on Saturday 5th of December 2009 09:04:03 AM

both copies reported by the command lslv are on the physical volume of rootvg: hdisk0 and hdisk1.

Both copies will not affect the datavg vg.

In fact I try to delete, without impacting applications, the problem of name conflict logical volume on this server. There are two times the logical volume lvnode01 : once in the volume group rootvg (mounted and active) and a second time in another volume group datavg (unmounted, not in the ODM but present in VGDA off physical volume related volume group datavg).

After some research I think the command synclvodm could solve the problem of name conflict by renaming the logical volume automatically by default.

NAME
vgremove - remove LVM volume group definition from the system SYNOPSIS
vg_name ... Remarks If a combination of volume groups version 1.0 and 2.0 or higher arguments are supplied, then the arguments might not be processed in the order they are listed on the command line. DESCRIPTION
The command removes from the system the last physical volume of the volume group and the definition of the volume group or groups specified by vg_name .... Since all system knowledge of the volume group and its contents are removed, the volume group can no longer be accessed. To move a volume group from one system to another, use the command instead (see vgexport(1M)). Before executing remove all logical volumes residing on the last physical volume by executing (see lvremove(1M)). Before removing a volume group, two steps are necessary: 1. Remove all the logical volumes belonging to the group by using the command (see lvremove(1M)). 2. Remove all but one physical volume belonging to the volume group by using the command (see vgreduce(1M)). If there is any physical volume group created under vg_name ..., the physical volume group information is also removed from file Options and Arguments recognizes the following option and argument: For each volume group removed, also remove its volume group directory and file vg_name The path name of a volume group. EXTERNAL INFLUENCES
