filesystems inside disk group

hi all,

I am trying to find out if a particular filesystem which belongs to a disk group can be taken offline and mounted on another host, we have a disk group which has file systems for 5 databases, i am checking if a couple of filesystems belonging to a particular DB can be taken offline and mounted on another hosts, keeping the rest of the 4 db's filesystem intact .

 

Thank you

Jonu Joy

Hi, That is not possible ...

Hi,

That is not possible ... there are 2 scenarios however in both of them you can't take some filesystems belonging to a diskgroup online to other hosts

if this is a standalone host:

If this is a standalone host, you need to deport the veritas diskgroup & import on other node if you want to access disk & volumes on other hosts. For this, the Luns underneath the diskgroup should be visible to other node so that diskgroup can be deported from current node & import to other node however in this case as well, at a time, DG will be imported only one node & filesystems can be online on one node only.

If you have clustered host:

In this case as well, diskgroup will be part of some cluster group where clustered group can be online on any one node & diskgroup & filesystems can be online on one node at a time.

Another solution is to use

Another solution is to use Cluster File System and make that diskgroup and file systems available to both nodes at the same time

If these filesystems are on

If these filesystems are on independent disks/luns and you have SF Enterprise, you should be able to unmount the filesystems and split the volumes/disks into a new diskgroup. 

You can then deport the diskgroup that was split off and import on the other system.
