Migration in AIX

Migration

First we need to extend rootvg to new harddisk. Rootvg is on hdisk0 & we want to migrate on hdisk1

# extendvg rootvg hdisk1

# bootinfo –b                      to check boot disk

# bootlist –m normal -o    check bootlist

Hdisk0    blv=hd5

cd0

ent0

# migratepv  hdisk0  hdisk1     to migrate pv from old hdisk to new.

# bosboot –ad hdisk1       BLV not get transferred. We should transfer it manually.

# bootlist –m normal -o   Check whether BLV transferred or not

Now change boot list

# bootlist –m normal hdisk1 cd0 ent0

Now clear PP from old harddisk

# chpv –c hdisk0                      to change the state of PV in a VG

# reducevg rootvg hdisk0      to reduce volume group

# chdev –l hdisk0 –a pv=clear  to clear PID

# bootlist –m normal –o

hdisk1    blv=hd5

cd0

ent0

# rmdev –dl hdisk0                       to remove hdisk
