Hi,

>How do you confirm failed
disk?

Check any stale PE in pvdisplay -v
Check disk in ioscan
Check syslog for any errors
Check event logs for disk failure alert

>How u restore back?
Check this document: http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

>Are the server need to shutdown ?
Depends on server. If disk is hot swappable then you need not to reboot.
