New lvol

David Dangerfield_1 — Thu, 04 Dec 2008 19:56:55 GMT

I had to replace a internal hard drive. Once done I need to create VG, LVOL etc. While trying to do this I see the replace hard drive as unused. Select that drive to create all items. Once i try to add it comes back that vg01 already exist. Is there a way to clear that out so i can use that vg01 as my VG.

THANKS

Hi David,

While creating the vg,plz check the following

ls -l /dev/vg*

make sure the vg name not exist. if exist remove it .

we have to create a group file for the vg creation using

mknod /dev/vg*/group c 0x0nn0000.

hence follow the lv creation.

Thanks,
Analyst.

If you are replacing a disk for vg01 then you should do

vgcfgrestore -n /dev/vg00 /dev/rdsk/cxtydz

Sorry it should be vg01
#vgcfgrestore -n /dev/vg01 /dev/rdsk/c0t7d0

if you do not want to restore then make sure vg01 not in use then do #vgexport vg01

Hi David,

>>"I had to replace a internal hard drive"

Was this drive in use before?

>>"Once done I need to create VG, LVOL etc"

Same structure as on the old drive?

If yes, then have a look at:
