Re: LV & PV issue !!!!
I was probably wrong. You are using a dual port HBA, 2/0/8/1/0/4/0... and 2/0/8/1/0/4/1..., I overlooked this.
However,
Cur PV 16
Act PV 11
means, there are 16 configured "disks", but only 11 are available. So you have no access to 5 disks/LUNs. Compare your ioscan with the VG configurations to find out which are missing.
Hope this helps!
Regards
Torsten.

Re: LV & PV issue !!!!
Hi Yogesh,
You can use vgreduce -f option,
This option does not require a physical volume to be supplied on the command line. vgreduce obtains the name of each physical volume belonging to the volume group from the file /etc/lvmtab. It then reads the LVM structures from each PV and compares these with that held by the kernel to work out which PVs are missing. PVs which are missing will be candidates for removal. If all the physical extents on the missing PV are free then it will be removed from the volume group
