vg00 and directory structure

[christian_derek]

Hi,

On my hpux 11iv3 I need to build some vg (lun from EVA4400) and I was wondering how should I do this.

I have currently vg create in this format vg_client1_prod vg_client1_test

and logical volume
/dev/vg_client1_prod/lvol_data
/dev/vg_client1_prod/lvol_opt
/dev/vg_client1_prod/lvol_etc

Here is the final result I want ...

/prod/client1/data,/prod/client1/apps,/prod/client1/var ...
/prod/client2/data ...
/test/client1/data ...
/train/client1/data ...

should I build on vg00 my structure /prod/client1,/test/client1 and /train/client1 and mount my file system to /prod/client1/data from my lv lvol_data?

Thanks,

It is generally not a good idea to put application data on vg00. vg00 should be reserved for operating system. Rest of the data should be placed on a separate volume group or groups, depending on your preference. This way, especially data residing on SAN, you will have a chance of exporting these separate volume groups and after rezoning the devices to a different server, you cana import them on a totally different server, say for backup purposes as the most common example that comes to mind.

Hi,

It is always good that you have you other volumes( data and app) in other VGs.

There are somany reasons for this.

Mirror, backup, management, availability everything..

Mounting you can do as you wish.

sorry for the confusion,

only /prod/client1 would be on vg00 and the rest will be mount point.

/prod/client1/data = /dev/vg_client1_prod/lvoldata

Thanks,
