By default Veritas Volume Manager uses HP-UX legacy naming scheme instead of the agile view. Below is a procedure to change this behaviour.
- Display VxVM disk information and get the current naming scheme.
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 auto:LVM - - LVM
c0t1d0 auto:LVM - - LVM
c0t2d0 auto:cdsdisk labdg01 labdg online
c0t3d0 auto:cdsdisk labdg02 labdg online
c0t4d0 auto:cdsdisk labdg03 labdg online
c0t5d0 auto:none - - online invalid
c0t6d0 auto:none - - online invalid
c0t7d0 auto:none - - online invalid
c0t8d0s2 auto:hpdisk rootdisk01 rootdg online
c0t9d0s2 auto:hpdisk rootdisk02 rootdg online
# vxddladm get namingscheme
NAMING_SCHEME PERSISTENCE MODE
===============================================
OS Native Yes Legacy
As shown the mode is set to legacy and the disks are shown with their legacy device names.
- To change this use again the
vxddladm
command.
# vxddladm set namingscheme=osn mode=new
The parameters used are namingscheme
and mode
. The available values for namingscheme
are:
-
ebn
: Enclosure based names. -
osn
: Operative system names.
If ebn is used neither legacy mode nor new mode can be set since hardware names provided by the disk array will be used. So osn as namingscheme is the right choice.
The mode
parameter is defines which naming model will be used in the osn naming scheme. The following values can be set:
default
legacy
new
- Check the change by executing the
vxdisk
andvxddladm
commands:
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
disk4_p2 auto:LVM - - LVM
disk6 auto:LVM - - LVM
disk8 auto:cdsdisk labdg01 labdg online
disk10 auto:cdsdisk labdg02 labdg online
disk12 auto:cdsdisk labdg03 labdg online
disk14 auto:none - - online invalid
disk16 auto:none - - online invalid
disk18 auto:none - - online invalid
disk20_p2 auto:hpdisk rootdisk01 rootdg online
disk22_p2 auto:hpdisk rootdisk02 rootdg online
# vxddladm get namingscheme
NAMING_SCHEME PERSISTENCE MODE
===============================================
OS Native Yes New
the naming scheme can be set back to the legacy scheme using the same procedure.
