Hello,

After creating VG and recheck, I can see that everything is fine for now.
Code:
[root@xxx] / > lspv
hdisk0          00fa6d1288c820aa                    rootvg          active
hdisk1          00fa6d1288c8213c                    vg_pt           active
hdisk2          00c1cc14d6de272b                    vg_3            active
hdisk3          00c1cc14d6de27e5                    vg_3            active
hdisk4          00c1cc14d6de2898                    vg_3            active
hdisk5          00c1cc14d6de2958                    vg_3            active
hdisk6          00c1cc14d6de2a07                    vg_3            active
hdisk7          00c1cc14716beb5c                    vg_3            active
hdisk8          00c1cc14816d37d0                    vg_pt           active
hdisk9          00c1cc14816d38a0                    vg_3            active
hdisk10         00c1cc14816d396c                    vg_3            active
hdisk11         00c1cc14716beb98                    vg_3            active
hdisk12         00c1cc14716bebd9                    vg_3            active

And the path is also ok now.
Code:
[root@xxx] / > lsmpio
name     path_id  status   path_status  parent  connection

HDISK1 and HDISK8 are empty disks. Create a volume group on it and check it out. :-)
How can you know they are empty disks?As we can think the system is using it as non-LVM disks? And second question is, the multipath should also work for them right? Why after adding to LVM, the multipath starts working? Smilie
