lvlnboot -R

Shehan — Mon, 30 Mar 2009 05:06:18 GMT

Hi Team

I wanted to run vgscan command in hp-ux 11 v1 in order to create new lvmtab. Once i run it , it says me to run below command as it is being configured secure path
*** #1. vgchange -a y
*** #2. lvlnboot -R

1) if I execute above command, is it required to reboot the server
2) Do I really need to execute above command ?

Hi,

I think no need to run above command to create a new lvmtab.
Just rename the old lvmtab to lvmtab.org then run vgscan
it will create a new lvmtab

and no need to reboot the server.

Hi Suraj
i also think there is no requirement to reboot.Also all VGs are visible after run VGSAN command.But the problem is once I run this, it says below messages
*** LVMTAB has been created successfully.
*** If PV links are configured in the system.
*** Do the following to resync information on disk.
*** #1. vgchange -a y
*** #2. lvlnboot -R

As i already configured PV links, Do I need to run above two command in order resync information?

Hello,

don't be worried by these messages.
vgchange -a y will activate your VGs if they are not.
lvlnboot -R will recover missing links but is used when you add new disk in logical volume principaly.

as you have just recreated the lvmtab you don't need to do anything else.

Regards.

Shalom Nirushita,

When I create a new /etc/lvmtab I leave a backout path.

mv /etc/lvmtab /etc/lvmtab.backup
vgscan -a

Hi,

If you run those below commands,

*** #1. vgchange -a y
*** #2. lvlnboot -R

then also no reboot is required.
