powerpath linux 5.6 and vxdmp 6.0 - procedure to clean and remove PP devices

Hi guys,

ENV:

pp 5.6

Red Hat Enterprise Linux Server release 5.8 (Tikanga)

VRTSvxvm-6.0.001.000-RP1_RHEL5

Array : VMAX

Is there an EMC recommended procedure to remove PP pseudo devices under vxdmp ?

I have faced some kernel panic in the past.

Thanks for your help.

JJ.
