LVM - pvcreate Error - "No such device or address"

This is was happened:

A non-RAID disk has gone bad.

disk    8  0/4/1/0.0.0.5.0      sdisk          NO_HW       DEVICE       HP      DG146BB976

You replace it and you get a new device file on a new hardware path:

disk        18  0/4/1/0.0.0.7.0        sdisk          CLAIMED     DEVICE       HP      EH0146FARWD

Now you say "please use the new device as a replacement for the old device":

# sasmgr replace_tgt -D /dev/sasd0 -q old_dev=/dev/dsk/c1t5d0 -q new_tgt_hwpath=0/4/1/0.0.0.7.0

and you see

disk         8  0/4/1/0.0.0.5.0        sdisk          CLAIMED     DEVICE       HP      EH0146FARWD

but the system remembers the "new" device, now as "NO_HW", because it became the replacement for the "old" device.

disk        18  0/4/1/0.0.0.7.0        sdisk          NO_HW       DEVICE       HP      EH0146FARWD

This will become a bit more complicated if you use 11.31 ;-)

So better use a hardware RAID (like your vg00), if possible.

Many thanks for the assistance Torsten, the disk is now claimed and back in the VG.  All OK now.
