If you stop the SF service and then start it again by installer, the permission on dmpnode will get lost.
For example:
You check the permission on dmpnode at first:
# ls -l /dev/vx/dmp/huawei-hvs88t0_0
brwxrwxrwx 1 vdsm kvm 201, 1728 Jan 22 02:08 /dev/vx/dmp/huawei-hvs88t0_0
You stop the SF service by installer:
# /opt/VRTS/install/installer -stop
You check the permission on dmpnode:
# ls -l /dev/vx/dmp/huawei-hvs88t0_0
brwxrwxrwx 1 vdsm kvm 201, 1728 Jan 22 02:08 /dev/vx/dmp/huawei-hvs88t0_0
You start the SF service by installer:
# /opt/VRTS/install/installer -start
When you check the permission on dmpnode, the user/group/permission gets lost:
# ls -l /dev/vx/dmp/huawei-hvs88t0_0
brw------- 1 root root 201, 1712 Jan 22 02:29 /dev/vx/dmp/huawei-hvs88t0_0

Workaround:

You can restore the permission through chmod.
