Thanks very much, ibmtech.

When I try out the lspv command on the active and inactive nodes of the cluster, I see:

Code:
lihbidbp12pf:/home/lc25487 $ lspv
hdisk0          0005493a0a9eb0e2                    rootvg          active      
hdisk1          0005493a0a9eb1dd                    vg_scratch      active      
hdisk2          0005493a0a9eb3c4                    vg_fs1          active      
hdisk3          0005493a0a9eb4bf                    vg_fs2          active      
hdisk4          0005493a0a9eb6ab                    vg_fs3          active      
hdisk5          0005493a0a9eb7a6                    vg_fs4          active      
hdisk6          0005493a0a9eb98d                    vg_fs5          active      
lihbidbp12pf:/home/lc25487 $

on the actove node and I see:

Code:
lc25487@lihbidbp11pf: $ lspv
hdisk0          0005493a0a9eaef8                    rootvg          active      
hdisk1          0005493a0a9eb1dd                    vg_scratch                  
hdisk2          0005493a0a9eb3c4                    vg_fs1                      
hdisk3          0005493a0a9eb4bf                    vg_fs2                      
hdisk4          0005493a0a9eb6ab                    vg_fs3                      
hdisk5          0005493a0a9eb7a6                    vg_fs4                      
hdisk6          0005493a0a9eb98d                    vg_fs5                      
/home/lc25487

on the inactive node. I guess this means I do not have any concurrent filesystems, and that hdisk1-hdisk6 (with the same value in the 2nd field on each line) are attached to whichever node is active. The '-l' option on hdisk1 gives me:

Code:
lihbidbp12pf:/home/lc25487 $ lspv -l hdisk1
hdisk1:
LV NAME               LPs     PPs     DISTRIBUTION          MOUNT POINT
lv_3500               16      16      00..16..00..00..00    /3500
home_lv               48      48      00..48..00..00..00    /3500/home
lv_sca                96      96      96..00..00..00..00    /SCA
scr_lv                96      96      00..45..51..00..00    /3500/scratch
lv_orsyp              96      96      00..00..57..39..00    /3500/orsyp
download_lv           96      96      00..00..00..70..26    /3500/download
lihbidbp12pf:/home/lc25487 $

So I guess these are all logical volumes within hdisk1.

Again, thanks for the info.

lvremove

LVREMOVE(8)						      System Manager's Manual						       LVREMOVE(8)

NAME
       lvremove - remove a logical volume

SYNOPSIS
       lvremove  [-A|--autobackup  {y|n}]  [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] LogicalVol-
       ume{Name|Path} [LogicalVolume{Name|Path}...]

DESCRIPTION
       lvremove removes one or more logical volumes.  Confirmation will be requested before  deactivating  any	active	logical  volume  prior	to
       removal.   Logical  volumes  cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem).  Removing an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS
       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

       --noudevsync
	      Disable  udev  synchronisation. The process will not wait for notification from udev.  It will continue irrespective of any possible
	      udev processing in the background.  You should only use this if udev is not running or has rules that ignore the devices	LVM2  cre-
	      ates.

EXAMPLES
       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

       lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

       lvremove vg00
