question:

1. why I can't find  /dev/disk/disk2_p2 through ioscan as you can see from above result？

2. when I run： # pvcreate /dev/rdsk/c1t2d0
pvcreate: The physical volume already belongs to a volume group

How can I find which vg does this disk belong to? seeing from the vgdisplay, I can only find vg00, and though vgdisplay -v  vg00, I can only find /dev/disk/disk2_p2 is used. How to know which vg used /dev/rdsk/c1t2d0 ?

Thanks.

I run vgscan -v, it seems there's another vg named vgping existed on the system.  How can I make it available or removed it cleanly?

Use

# ioscan -m dsf

and you will find the legacy device file for  /dev/disk/disk2_p2.
