Sync disk staus on Share disk

Hi all

At moment we've got server A and B connect to storage, and we share a disk between both servers.
The problem is whenever I use SAM to create a new lv on my existing vg, only the server which i create the lv can see the changes that are made. What can i do to make both server see the change that I made with out using export and import VG?

second question, is it possible to keep the LV's read write (rwxrwxrwx) behaviour and owner? it is annoying after importing the VG it got change back to 440 and owner root:sys

Thanks very much

The VG information is stored locally - for this reason you need to vgexport (preview mode) and vgimport this information to make it available to other hosts.

Where do you have rwxrwxrwx rights???

Thanks for replying

you get to change read/write behaviour when you change into the VG directory (eg. /dev/vg01/) and then you can use the "chmod" command to change it.

so from your answer there's no way I could add an lv without shutting down by database?
I'll have to shutdown the service then do export and import on the 2nd server?

If you vgexport the disks in preview mode, you don't need to stop or shutdown anything.

Still not sure about what files have this "worldwide" permissions...

What I need is not possible to achieve.
