Adding persistent dump volumes to a VxVM rootable system
A persistent dump volume is used when creating crash dumps, which are eventually
saved in the /var/adm/crash directory. A maximum of ten VxVM volumes can be
configured as persistent dump volumes.
Persistent dump volumes should be created and configured only on the current
boot disk. The extent information of the persistent dump volumes is written to
LIF label record of the boot disk and is required during early boot time.
To add a persistent dump volume to an HP-UX system with a VxVM root disk
1
Create the VxVM volume that is to be used as the dump volume in the boot
disk group:
# vxassist -g bootdg make dumpvol 5g
In this example, the size of the volume is 5 gigabytes.
2
Display the configuration of the volume:
# vxprint -g bootdg
3
Display the initial crash dump configuration:
# crashconf -v
4
Add the volume as a persistent dump device to the crash dump configuration:
# crashconf -s /dev/vx/dsk/bootdg/dumpvol
5
Display the new crash dump configuration:
# crashconf -v
Removing a persistent dump volume
Warning: The system will not boot correctly if you delete a dump volume without
first removing it from the crash dump configuration.
Use this procedure to remove a dump volume from the crash dump configuration.
