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.
