Hello Guys,
I need a little help here. I have been studying crash dump and per what I am reading, you can dedicate a slice to use as a dump device. Now when you dedicate this slice, do you have to :
1) create a mount point?
2) add entry in /etc/vfstab?
3) is this slice wu or wm?
4) should... (3 Replies)

dump
dump(9E) Driver Entry Points dump(9E)
NAME
dump - dump memory to device during system failure
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int dump(dev_t dev, caddr_t addr, daddr_t blkno, int nblk);
INTERFACE LEVEL
Solaris specific (Solaris DDI). This entry point is required. For drivers that do not implement dump() routines, nodev(9F) should be used.
ARGUMENTS
dev Device number.
addr Address for the beginning of the area to be dumped.
blkno Block offset to dump memory.
nblk Number of blocks to dump.
DESCRIPTION
dump() is used to dump a portion of virtual address space directly to a device in the case of system failure. It can also be used for
checking the state of the kernel during a checkpoint operation. The memory area to be dumped is specified by addr (base address) and nblk
(length). It is dumped to the device specified by dev starting at offset blkno. Upon completion dump() returns the status of the transfer.
When the system is panicking, the calls of functions scheduled by timeout(9F) and ddi_trigger_softintr(9F) will never occur. Neither can
delay(9F) be relied upon, since it is implemented via timeout(). See ddi_in_panic(9F).
dump() is called at interrupt priority.
RETURN VALUES
dump() returns 0 on success, or the appropriate error number.
