find multipath version or kernel module

brian_31 — Fri, 17 Sep 2010 15:55:39 GMT

I want to know if the vxdmp drivers are loaded on a HP-UX box. What command would give me that info? also the dmp driver version if possible. Please note we have full vxvm license.

Thanks

Brian

Hi Brian:

Have a look at 'kcmodule'. see the manpages for more information:

Hi (again) Brian:

For 11.11 have a look at 'kmadmin(1M)'.

Regards!

I am pretty sure vxvm multipathing is not included in base vxvm so with LVM you can use pvlinks for failover to different paths.

If you need multipathing your disk array vendor probably has a optional software product for HPUX to provide the load balancing feature.

swlist will show what version of (base-)vxvm is installed, can be vxvm 3.2 or vxvm 3.5 on hp-ux 11.11, and swlist will also show if the "full" vxvm product is installed.

# swlist|grep -i veritas

To check if vxvm was allready "setup", check if the vxconfigd daemon is running.

# ps -ef|grep vxconfigd

If the vxconfigd daemon is not running, vxvm was not yet "setup" and vxinstall needs to run, to get it setup.
I suppose the vxvm admin guide will take you through the vxinstall setup.

Afterwards, the full vxvm license can be "crosschecked" with the command.

# vxdctl license

If it says "DMP (multipath enabled)" the full vxvm product is installed, if it says DMP (single path enabled) only base-vxvm is installed.

Everything is included in the base-vxvm product. The full vxvm product is only a license file.
