Mirroring

# lspv

# lsvg –L rootvg

# extendvg rootvg hdisk1          extend rootvg to new harddisk. Rootvg is on hdisk0

# bootinfo –b                      to check boot disk

# bootlist –m normal -o    check bootlist

# mirrorvg rootvg  hdisk1     to create mirror image of hdisk0 to hdisk1

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

Check whether BLV transferred or not

# bootlist –m normal -o

Now change boot list

# bootlist –m normal hdisk0 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

Hdisk0    blv=hd5

Hdisk1    blv=hd5

cd0
