AIX Volume Group can’t properly display the Logical Volume Type

Listing the logical volumes inside the volume group. AIX can’t determine the LV type.

root@aix:/ # lsvg -l oravg
oravg:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
oravg_lg            ??? 1     1     1    closed/syncd  N/A
ora_lv              ??? 1064  1064  2    closed/syncd  N/A

To solve this problem we’ll export then reimport the VG. But first we’ll need to deactivate it.

root@aix:/ # varyoffvg oravg

And we need at least one disk that is part of the volume group because it has the information needed to import.

root@aix:/ # lspv | grep oravg
hdisk251
00c5f1d097cc8a6e                   oravg
hdisk221
00c5f1d0a7bffede                    oravg

Now we run exportvg and the server will no longer know it once had the volume group.

root@aix:/ # exportvg oravg

Let’s list all the volume groups the server is aware that exists.

root@aix:/ # lsvg
rootvg
datavg
cache01vg
cache02vg

Only the rootvg is currently imported and active.

root@aix:/ # lsvg -o
rootvg

Let’s reimport the volume group. We need to declare one of the disks we listed before to reimport the volume group.

root@aix:/ # importvg -y oravg hdisk251
oravg

Next, we activate the volume group

root@aix:/ # varyonvg oravg

Listing the Volume Group. Volume Group TYPE listed.

root@aix:/ # lsvg -l oravg
oravg:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
oravg_lg            jfs2log    1     1     1    closed/syncd  N/A
ora_lv              jfs2       1064  1064  2    closed/syncd  /u01
