Reinitializing a User-Defined Volume Group

To reinitialize a user-defined volume group, copy the shell script to a new file /bin/uvgrecover, edit the file as follows, and then run chmod +x /bin/uvgrecover.

After copying the shell script to /bin/uvgrecover, change the line:

odmdelete -q "value1 = 10" -o CuDvDr

To:

odmdelete -q "value1 = $VG" -o CuDvDr

The physical volume (PV) and volume group (VG) variables on the first two lines of the script are defaulted for the rootvg volume group. The PV is set to /dev/ipldevice, which is a synonym for one of the physical volumes that is a member of the rootvg volume group. For a user-defined volume group:

• Change the PV= line to be any of the disks that is a member of the volume group in question. To determine to which volume group a physical volume belongs, enter:

  lsvg `lqueryvg -vp hdisk# ` | grep GROUP

  Note: The ` is a grave accent, not a single quote mark. This key is usually found above the Tab key.

• Change the VG= line to be the volume group in question.

For example:

PV=/dev/hdisk1
VG=uservg
