one of 2 fibre cable pulled and vg deactivated. now can't acitvate VG ?

[Sammy_2]

HPUX 11.11
I pulled the cable to c11 intentionally
Now when I try to activate the vg, it tells me device does not exist (which is correct). But, I forgot to vgreduce the c11 path from VG before deactivating the VG. Now, I want to go back and vgreduce in order to do that, I need to activate the VG. How can i go about activating the VG ?


# vgchange -a y ops

vgchange -a y ops

Hi Sammy,

can you please try doing to activate it and post the results.

# vgchange -a y -q n ops

Pretty much same thing. I am thinking of
rename lvmtab. and then do a vgscan. Will that take care of it.

ojrdhes3:/etc ==> vgchange -a y -q n ops

well, as i know vgscan will not consider the unconfiugred/deactivated VGs. But it does include those VGs which are activated during its last boot.
you can give it a try by having a proper backup of your /etc/lvmtab.

Also, i noticed this line in your error that

***** vgchange: Activation mode requested for the volume group "/dev/ops" conflicts with configured mode. ***********

is this volume group is a part of the cluster?

Can you paste the output of the current /etc/lvmtab.

a very small correction in my previous post,

******** vgscan will recover a volume group only if it has been activated at least once since the last boot, and the Volume Group ID is unique********

Hi,

Please post the output of strings /etc/lvmtab and strings /etc/lvmtab**old -- if you have move lvmtab before.

Also post output of ioscan -fnC disk
