Re: Stlale extents
this error could be tricky. Please, run
dd if=/dev/dsk/cXtXdX of=/dev/null bs=128k
on each of the drives and see if any would give error to confirm which disk is actualy defective. We would then workmm on the defective drive.
You can reduce the bs size if there is no error.
Hope you have tried to re-sync the drives before all these.
lvsync /dev/vg00/lvol7

Re: Stlale extents
The next step is. Do you have a good lvmconf file?.
check the /etc/lvmconf/vg00 and confirm that the file is a good one. Are we discusing on RISC server or Itanium.

Re: Stlale extents
I would suggest to physically remove the device after shutdown and then try booting through the disk having only 2 stale PE's. This should not give any problem if the LVOLs are quite free, and if it gives errors you will have to recover /usr from a good backup.
I do not think you can avaoid a outage here, as even if you replace the disk and resync you cannot conform functionality without booting from both disks indivisually.
Here is the official disk replacement guide

Re: Stlale extents
It would be good to hear the steps taken.
My thoughts are to setup a PVG including the mirror disk and do an lvplit to get /usr only on primary disk. then try to mirror back to the "mirror" disk. If that works then you should follow normal procedures for replacing a a vg00 disk. If it still fails due to the 2 bad extents you could try to cheat if you have at least 2 extents available.
1. create a dummy lvol up to those bad extents
2. create a 2nd dummy lvol on those 2 extents.
3. lvremove the 1st dummy lvol
4. mirror /usr to the "mirror" disk.
If the 2 disks were not configured corrctly ( mirror disk was not properly configured to boot off of) in the first place then all bets are off.
