AIX Volume Group can’t properly display the Logical Volume Type
Posted by Emerson Takahashi on October 13, 2009
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
