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?

cr_verify
cr_verify(3) Library Functions Manual cr_verify(3)
NAME
cr_verify - verify integrity of crash dump
SYNOPSIS
DESCRIPTION
uncompresses and verifies the sizes and checksums of every file in the crash dump identified by crash_cb.
flags is a bitmask of zero or more of the following flag values:
will not attempt to verify checksums of files in the crash
dump if this flag is set. Only sizes will be verified.
will write messages to stderr during time-consuming operations
(decompressions and checksums) if this flag is set.
will write messages to stderr describing any validation problems
that are encountered. If this flag is set, should not be called when returns; repeated error messages would result.
RETURN VALUE
Returns zero for success. Other possible return values are described in libcrash(5).
EXAMPLES
The following call to cr_verify(3) verifies the integrity of the dump.
WARNINGS
Because it uncompresses and checksums all files in a dump, can be very time-consuming. If was not specified, the calling application
should notify its user before calling that there may be a significant delay.
