chdev -l hdisk1 -a pv=yes
will assign a Physical Volume ID (pvid) to hdisk1.
This is from an IBM doc on replacing a disk:
"Adding a new drive to an existing volume group"
Once the new drive has been configured, ensure that a proper PVID has been
written to the drive by running:
chdev -l <hdisk#> -a pv=clear
chdev -l <hdisk#> -a pv=yes
I guess the disk you added had a pvid which was fine for your system to use.

Subject: Running chdev
Hi,
I remember once that when one of the SSA disk had failed. I
replaced it and then ran cfgmgr -vl ssar and then did a extendvg to add the
disk to the appropriate diskgroup.I did not run any other commands. But, the
IBM document says that after you add a disk and after running cfgmgr, you
will have to run chdev -l hdisk1 -a pv=yes. Is this true and if yes why...?
Thanks,
shekar
