Cleaning up the alternate disk volume group when LVM rootvg is enabled for DMP

When the LVM rootvg is enabled for DMP, use the procedures in this section to clean up the alternate disk volume group. The clean-up process removes the alternate root volume group (altinst_rootvg) from the AIX Object Data Manager (ODM) database. After you clean up the alternate disk volume group, the lspv command output displays 'None' for the altinst_rootvg. The command does not remove any data from the disk.

To clean up the alternate disk volume group when LVM rootvg is enabled for DMP

  1. Verify that LVM rootvg is enabled for DMP. The alternate disk volume group to be cleaned up is altinst_rootvg.
    # lspv | grep rootvg
hdisk59         00c408c4cc6f264e             rootvg	active
hdisk62         00c408c4cc6f264e             rootvg	active
hdisk65         00c408c4cc6f264e             rootvg	active
hdisk68         00c408c4cc6f264e             rootvg	active
ams_wms0_491    00c408c4dbd98818             altinst_rootvg
  2. Show the DMP node names.
    # vxdmpadm native list
PATH                      DMPNODENAME
==============================================
hdisk59                   emc_clariion0_137
hdisk62                   emc_clariion0_137
hdisk65                   emc_clariion0_137
hdisk68                   emc_clariion0_137
  3. Clean up the alternate disk volume group, altinst_rootvg.
    # alt_disk_install -X altinst_rootvg
  4. Display the configuration.
    # lspv | grep rootvg
hdisk59         00c408c4cc6f264e             rootvg	active
hdisk62         00c408c4cc6f264e             rootvg	active
hdisk65         00c408c4cc6f264e             rootvg	active
hdisk68         00c408c4cc6f264e             rootvg	active
