HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

1. (11i v2 and above) Beginning with HP-UX 11i v2 and therefore vPars A.04, the savecrash
processing has changed. Instead of copying the kernel file that was in use during the crash,
the directory /stand/crashconfig is copied. Therefore, prior to executing the crashconf
and savecrash steps below, create the /stand/crashconfigdirectory using
# kconfig -s crashconfig
Or if the kernel configuration used in the last boot is different from the current kernel
configuration, use the -c option. For example, if the saved kernel configuration is named
kc.custom, the command is
# kconfig -c kc.custom crashconfig
For more information on using the kconfig command, see the manpages kconfig(5) and
kconfig(1M)
2. Obtain of list of dump devices, noting the DEVICE and OFFSET information:
# crashconf -v
DEVICE OFFSET(kB) SIZE(kB) LOGICAL VOL. NAME
-------------- ---------- --------- ------------- --------------
31:0X022000 314208 4194304 64:0X000002 /dev/vg00/lvol2
The DEVICE is 31:0X022000, and the OFFSET is 314208.
3. Map the device number from the DEVICE information to a device file:
# ls -l /dev/dsk /dev/disk | grep "31.*022000"
brw-r----- 1 bin sys 31 0x022000 Oct 13 2001 c2t2d0
The corresponding device file is /dev/dsk/c2t2d0.
4. Using the OFFSET information and the device file, save the dump to /var/adm/crash:
# savecrash -r -f -D /dev/dsk/c2t2d0 -O 314208
Network and Tape Recovery
This section covers different methods of network and tape recovery on vPars systems. The
following table lists the supported recovery methods on each vPars release.
Table 10-1 Supported Recovery methods by vPars Release

environment
yesyesyesTape recovery within a vPars
environment, using a disk-based
install kernel (dual-media boot)

environment
For information on performing a recovery using:
• make_net_recovery within a vPars-environment, see “Using make_net_recovery
within a vPars Environment” (page 285)
• make_tape_recovery outside of a vPars-environment, see “Using make_tape_recovery
Outside of a vPars Environment” (page 287)
