- Hi there -- I am qualified to answer only for your a) question. Here's what
- I have. This message:
-
- Warning: unable to configure dump device...using primary swap instead.
- core image of 3071 pages will be saved at block 192821 on device 0x70e0500
-
- Comes from the fact that there is an undocumented kernel parameter to
- specify to which physical device the kernel will write a kernel core dump.
- Because this undocumented parameter was not set in your dfile, you get this
- message. If it were necessary for HP support people to redirect the output
- from the kernel routine "savecore", not to be confused with the command
- savecore(1m), to some other device then we could dig up this information
- and get it to you.
-
- In the meantime, it is better to leave it as it is, as it defaults to your
- primary swap area which is available for this task after a panic anyway.
- There are normally few reasons to change it.
-
- To verify this try this: (as root -- BE CAREFUL !!!!!)
-
- # adb /hp-ux /dev/kmem <----- You type this
- executable file = /hp-ux
- core file = /dev/kmem
- - warning: core file is mem or kmem
- ready
- _dumpdev/X <----- You type this (you do NOT
- _dumpdev: 0x70E0500 get a prompt)
- <cntrl>d <----- You type this
- #
-
- Note that 0x70E0500 maps to the number that was reported at boot time.
-
-
- hope this helps ....................
