perhaps the device driver has been hammered.

insf -e will probably help set things right.

Hi Jannik,

You obviously have a typo in your /etc/fstab file of some sort.
I suspect it's probably supposed to be /dev/cdrom & it contains /dev/odm OR you're supposed to have a device /dev/odm which you don't OR there's an LV beneath /dev/odm that you didn't enter into the fstab file.

HTH,
Jeff

Hey,

The thing is that i got the odm runnig with:
kmadmin -L odm
and started the cluster but i can't get the db's running i think that it may be:
/dev/odm/cluster
taht looks like this:
cluster status: disabled

it should be
enabled

????

Hi (again) Jannik,

I admit I had to go look this one up - ODM is Oracle Disk Manager & it's a function of Veritas Database Edition 3.5. And deals with Veritas' handling of raw Oracle devices & files.
But since you mentioned Service Guard, I have to question why an SG controlled device would be referenced in the fstab file.
Normally *all* SG devices are controlled by the cluster/pkg ascii files & not LVM definitions.
It may boil down to understanding how DBE is supposed to be utilized in a SG cluster.

Rgds,
Jeff

In the LVM world
lvchange -c y /dev/vg_name
enables the cluster-aware bit.
Check your Veritas docs to see if that's the way or for the Veritas method.

Jannik — Mon, 08 Mar 2004 19:36:07 GMT

this is the way Veritas RAC/VCS recommend to do it.
I just didn't know that the dec03 patch bundle deleted loadable moduels for files, but for everybody else, you may have some odm problems after installing patches :-).
