Hello,

Can we create solaris volume manager volumes on
the vxdmp metanodes from "/dev/vx/dmp" and
"/dev/vx/rdmp" directories?

Thanks and Regards,
Mannu.

If I try, using a "/dev/vx/dmp" devices on metadb and metainit,

-bash-3.00# metainit d21 1 1 /dev/vx/dmp/c4t50060E801045A412d4s6
metainit: solaris160: /dev/vx/dmp/c4t50060E801045A412d4s6: No such
file or directory

-bash-3.00# metadb -a -c 3 -f /dev/vx/dmp/c4t50060E801045A412d4s6
metadb: solaris160: /dev/vx/dmp/c4t50060E801045A412d4s6: No such file
or directory

I am getting errors.

Can some one please help on this?

Why would you want to use Solaris Volume Manager on top of Veritas?
Use on VM to manage another. You should use one or the other and not
both, unless you use SVM to mirror your root disk and Veritas to
manage your other then root disk storage since, IMHO, it's easier to
break the mirror of SVM then Veritas if you need to recover booting of
the boot disk if something drastic goes wrong with upgrading Veritas.

If your going to use the CxTxDx device, why put it under Veritas
control? The /dev/vx/dmp and /dev/vx/rdmp are veritas multipathing
devices. So you can't do it. If you want to access the veritas
volume, you'll need to create one and specify the volume that's
created under /dev/vx/rdsk/<group>/<volume>.

Again, I don't see why you would use SVM ontop of Veritas VM.
