Using crashconf to Specify a Dump Device
You can use crashconf to directly specify the devices to be configured.
Table 5-12 describes how to use the crashconf command to add to, remove, or
redefine dump devices.
Table 5-12. crashconf Commands
Task Command
Add any dump devices
listed in fstab to the
currently active list of dump
devices
/sbin/crashconf -a
Replace the currently active
list of dump devices with
those defined in fstab
/sbin/crashconf -ar
crashconf reads the /etc/fstab file and
replaces the currently active list of dump
devices with those defined in fstab
Add devices, as specified /sbin/crashconf devicefile devicefile [...]
For example, to have crashconf add the
devices represented by the block device files
/dev/dsk/c0t1d0 and /dev/dsk/c1t4d0 to
the dump device list, enter
/sbin/crashconf /dev/dsk/c0t1d0 \
/dev/dsk/c1t4d0
Replace any existing dump
device definitions
/sbin/crashconf -r devicefile devicefile [...]
For example, to replace any existing dump
device definitions with the logical volume
/dev/vg00/lvol3 and the device represented
by block device file /dev/dsk/c0t1d0:
/sbin/crashconf -r /dev/vg00/lvol3 \
/dev/dsk/c0t1d0
