ioscan -fnC disk|grep NO -> look for not claimes Hard disk
1. vgreduce the failed disk

2. pvcreate
3. vgextend /dev/vgxx
mirror back all the logica volumes
4.lvextend -1 /dev/vgxx/lvolxx /dev/dsk/cxtxdx
Most recommended follow official document

And one more thing-the ioscan command will only give the H?W path of the disk.How can we able to identify the devicefile attatched to it?

Re: What is the procedure to identify a failed hard disk and for replacing the same in LVM.
If the device is in fact still connected and properly powered on, and its configuration has not been changed, that usually means the device has experienced a total failure, i.e. "died".
Sometimes a NO_HW indication is because of an intentional configuration change: for example, when you unpresent LUNs from a SAN, HP-UX will show the unpresented LUNs in NO_HW state. You can use the "rmsf" command to clean up such intentionally removed devices: in effect, you're telling the system that the device isn't expected to return to a working state.
