EMCPP and VXVM on same machine

Bedare Nikhil — Mon, 14 Sep 2009 11:28:27 GMT

Hi,
I have a HP machine with VxVM and EMCPP installed.I have couple of clariion disks connected to the machine with multiple paths.
The problem is I am seeing the paths claimed under both VxVM and EMCPP.I want them under EMCPP control only.

================
bash-2.05# vxdisk list EMC_CLARiiON0_2

Anyone has any idea about this ?

Thanks in advance,

Hi Nikhil,

Have a look at this doc.

That doc didnt help.Let me tell my problem more clearly.
The paths are seen under both EMCPP and VxVM control.I want them to be under EMCPP control only.
When I do vxdisk list ,it should show me the pseudo names like emcpower_0 etc.

Thanks.

A long time since I looked at this, but I seem to recall using the "vxddladm addforeign" command.

HTH

fully disable the access to the disks in dmp using below command:

vxdmpadm â f disable path=pathname

That doc was quite clear to me. VxVM detects the clarion pseudo device names. And in that doc you are told how to change from the clarion names to the native HP-UX names.

# vxdmpadm setattr enclosure enclosure tpdmode=native|pseudo

Hi,
The doc didnt help me on HP unix.If the vxvm shows me the pseudo names for the clariion disks,then my problem will be solved.Currently its showing the native names.

=====================
bash-2.05# vxdmpadm setattr enclosure EMC_CLARiiON0 tpdmode=pseudo
VxVM vxdmpadm ERROR V-5-1-11116 The given enclosure does not support this operation
======================

Thanks.
