AIX- Procedure to replace rootvg harddisk

Procedure of replacing rootvg failed hdisk

=================================

1)Ensure all LV in VG are mirrored. (lsvg -l rootvg)

2) unmirrorvg rootvg hdisk1 ( eg for hdisk1 is failed)

3) Check for any more LV on the hdisk to be removed (lspv -l hdiskx)

4) reducevg rootvg hdisk1 (if you receive error)

nlxenc06:a207081> reducevg rootvg hdisk1

0516-016 ldeletepv: Cannot delete physical volume with allocated

partitions. Use either migratepv to move the partitions or

reducevg with the -d option to delete the partitions.

0516-884 reducevg: Unable to remove physical volume hdisk1.

5) after getting error , try for reducevg -d rootvg hdisk1

even if you receive error

0516-914 rmlv: Warning, all data belonging to logical volume

hd7x on physical volume hdisk1 will be destroyed.

rmlv: Do you wish to continue? y(es) n(o)? y

0516-1252 rmlv: Warning, cannot remove logical volume hd7x.

This logical volume is also used as the secondary dump device.
