must /var/adm/crash fileystem be in root VG?

[Wayne King_1]

I am creating a separate filesystem for /var/adm/crash
but the current root vg has no free space. Is this
filesystem required to be in the root VG? I'm concerned
that other VGs may not be mounted/available at the point in the reboot where a
dump is being saved to
filesystem space.

The default directory for crash dump is /var/adm/crash,
however you could specify a different directory. This directory could be within
a file system that doesn't belong to the volume group vg00. Only You have to
modify the file /etc/rc.config.d/savecore (using vi), the variable SAVECORE_DIR
indicate the directory where the system going to generate the dump.
Note: the filesystem in which this directory is located should have as much
free space as your system has RAM.

good luck!

You could just link the /var/adm/crash to another directory in another volume
group with more space. Just man the ln command. This saves messing with the
settings for dumping kernel at crash.
