How do I remove a 'phantom' logical volume 1

[marcmcconnell]

On an IBM RS6000, I am having problems removing a logical volume. If I try to remove it through smit - I get an error "unable to find lv in the Device configuration database". Any ideas ? You can list the lv by doing a lsvg -l rootvg, but the TYPE is ??? instead of jfs.

Marc,

Well firstly did they have a JFS associated with it? if so does a stanza still exists in the /etc/filesystems file ? If you are not sure then look at the label field in the LVCB via:

getlvcb -AT <lvname>

The other possibility is that the definition for your vg is corrupted in the ODM you can either export/import or try:

syncvg -v <vgname>

If all else fails i.e. rmlv or smitty to remove use:

To try and delete the lv look at the LVCB of the lv in question and note the lvid field:

getlvcb -AT <lv_name>
ldeletelv -l <lvid>
syncvg -v <vgname>

N.B. This will only work if the lv has no allocated partitions i.e. if it is a ghost logical volume.

Best of luck and re-post any additional info.
