The /etc/fstab file
You can define entries in the fstab file to activate dump devices during
the HP-UX initialization (boot) process or when crashconf reads the
file. The format of a dump entry for /etc/fstab looks like the following:
devicefile_name / dump defaults 0 0
Examples:
/dev/dsk/c0t3d0 / dump defaults 0 0
/dev/vg00/lvol2 / dump defaults 0 0
/dev/vg01/lvol1 / dump defaults 0 0
Define one entry for each device or logical volume you want to use as a
dump device.
Unlike dump device definitions built into the kernel, with run time dump
NOTE
definitions you can use logical volumes from volume groups other than
the root volume group.

The crashconf command

You can also use the /sbin/crashconf command to add to, remove, or
redefine dump devices. The following are two ways to do this:
• Reread the /etc/fstab file using the crashconf -a option
• Use device arguments with crashconf to configure the devices
With either method, you can use the crashconf -r option to specify
that new definitions replace, rather than add to, any previous dump
device definitions.
Examples:
To have crashconf read the /etc/fstab file (thereby adding any listed
dump devices to the currently active list of dump devices), enter the
following command:
/sbin/crashconf -a
To have crashconf read the /etc/fstab file (thereby replacing the
currently active list of dump devices with those defined in fstab),
enter the following:
/sbin/crashconf -ar
