Just do "vxdisk rm <name>" on each of the ghost devices and check. VxVM 
sometimes keeps records of disks it has seen in the past

Hi All,

I need some help tips on this, basically I don't know the exact
history of this server but I just destroy the last DG and remove the
disk that is part of that DG on the VXVM control.

I did:

# vxvol -g dg_name stopall
# vxdg destroy dg_name
# vxdisk rm disk_name
# unbind the LUN(EMC)
# clear the dead paths
# devfsadm -C
# vxdctl enable
# vxconfigd -k

after that I got this this additional Devices(EMC_*): which not there
before when I run the same command.


# vxdisk list
DEVICE       TYPE            DISK         GROUP        STATUS

# vxdisk list EMC_CLARiiON1_0

c2t5006016039A0222Ed0s2 state=disabled
c2t5006016939A0222Ed0s2 state=disabled


My question is where did this coming from? And why it's not there
until I reset the vxconfigd?


TIA,

lupin
