Mirroring question -

I've setup mirroring of all lvols on the primary disk (followed HP documentation) -

When I use 'lvlnboot -v' the output is:

Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
        /dev/disk/disk3_p2 -- Boot Disk
        /dev/dsk/***c0t8d0s2*** -- Boot Disk
Boot: lvol1     on:     /dev/disk/disk3_p2
                        /dev/dsk/c0t8d0s2
Root: lvol3     on:     /dev/disk/disk3_p2
                        /dev/dsk/c0t8d0s2
Swap: lvol2     on:     /dev/disk/disk3_p2
                        /dev/dsk/c0t8d0s2
Dump: lvol2     on:     /dev/disk/disk3_p2, 0

Why is it showing legacy DSF rather than the new format /dev/disk/disk? ??

And does it matter?

I guess you used the legacy files while set up the mirror.

You can use "vgdsf" to convert

What device file did you use when you established the mirroring, the legacy or the perisstent?

Thanks you saved some man page reading and I'm already blind from reading man pages about how to create a single depot from multiples....Awesome, I'm done.

You can also just vgextend the persitent device file into the VG, it will see it as an alternate path, and then vgreduce the legacy device file out of the VG.

That is, basically, all the 'vgdsf' command (actually just a script in /usr/contrib/bin) does.
