Opinions: root mirror recovery

[Bliss, Kevin L]

You can. Either write a script to parse the output of vxprint -g
diskgroupname -vpshmQq (this file is consistent so should not take a lot of
effort) or use vxprint -pshmQqv volumename.  Both of these commands create
all of the gritty details necessary to recreate either an entire disk group
with all volumes, plexes, and subdisks (first example) or the volume (with
plexes, subdisks) in the second example.

For example, assume you have a volume named test1 in disk group Group1, that
somehow was destroyed and needed to be recreated.  If you had been
collecting the information above (i.e. vxprint -g Group1 -vpshmQq >
disaster.info.dgGroup1), you copy the file to test1.remake and manually (or
via a script) edit out all information except that pertaining to volume
test1.  Then you run the following command: vxmake -d test1.remake.  This
remakes the volume exactly as it had been.  In fact, if volume had been
deleted by mistake but the area on disk had not been reallocated to other
volumes and written to, the data will still be available.

After running the vxmake -d command, run the following:

vxvol init clean test1
vxvol start test1
If it was associated with a filesystem and the filesystem is still in the
vfstab then run:
mount /filesystemname
