issue AIX MPIO path closed

I have encountered the issue on my AIX 6.1. As you can see below, the hdisk1 & hdisk8 are not recognized by the system

[root@xxx] / > lspv
hdisk0          00fa6d1288c820aa                    rootvg          active
hdisk1          00fa6d1288c8213c                    None
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                    None
hdisk9          00c1cc14816d38a0                    vg_3            active
hdisk10         00c1cc14816d396c                    vg_3            active
hdisk11         00c1cc14716beb98                    vg_3            active
hdisk12         00c1cc14716bebd9                    vg_3            active

Futher checking on MPIO, I can see that the path(fcs0, fcs1, fcs3) for hdisk1 & hdisk8 are closed while for another hdisks are still working.

Can someone advise how to do and is there a way to manually change the state of the paths?
