Hello,


It's not from me, only from the man page.

well it depends what you are restoring.
If, for example, you had replaced a PV that was used to mirror another PV, then you could vgcfgrestore just that PV without deactivating the VG.
If you need to restore the whole VG, then this would definitely require the VG to be deactivated.
Read the man page for more info

If you replacing a bad disk and your system is at a current patch level, you must deactivate the physical volume (HDD) prior to restore the configuration:

e.g.

pvchange -a n /dev/dsk/c0t6d0
vgcfgrestore ...
pvchange -a y ...


In every case you have to activate the VG after this, e.g.

vgchange -a y vg01

For defective Disk (non-mirrored)
1.ioscan -fnC disk > ioscan.txt
2. replaced disk if hot swap disk
3. vgcfgrestore -n vg01 /dev/rdsk/cxtxdx
4. vgchange -a y
5. newfs -F vxfs /dev/vg01/lvol_name

For defective disk (mirrored)
1. vgcfgrestore -n vg01 /dev/rdsk/cxtxdx
2. vgchange -a y vg01
3. vgsync vg01

this will help.

Hi,

It is not mantatory to deactivate the VG.

there is an option -R to do a forceful restore too.

Bond,

we run,

3. vgcfgrestore -n vg01 /dev/rdsk/cxtxdx
4. vgchange -a y

vgchange -a y after restore just to resynchronyse the LVs.

Regards,

Siva.
