MirrorDisk

[f. halili]

I have a system right now & via SAM I could see that vg00 is mirrored. How can I check that via command line?

Is MirrorDisk separate product?
I did a swlist -l fileseet | grep MirrorDisk and got nothing.

thanks,
f. halili

Here is the product installed on hpux 11.11:

$ swlist | grep -i mirror
B2491BA B.11.11 MirrorDisk/UX

Here is how you tell what's mirrored:

$ bdf

/dev/vg00/lvol3 524288 97944 423048 19% /

Halili,

You can check with

#swlist | grep MirrorDisk/UX Or
#swlist | grep B2491BA

[Pete Randall]

If you look at a vgdisplay -v, you'll notice that Current LE is only half of Allocated PE - that's one way. Looking at lvdisplay, you'll see Mirror copies 1.

Quick and easy way:

lvdisplay -v /dev/vg00/lvolxx | more

It shows how mirror copies there are in the display.

Try running:
swlist | grep -i mirr

Rgrds,
Rita

Hello,

I checked one volume group below. So this is mirrored. Please see below.

But I still don't get anything with
#swlist | grep -i MirrorDisk
#swlist| grep -i mirror

The only "mirror" that I get in swlist -l is.
LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-RUN
LVM.LVM-RUN PHCO_29379.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN

This is not MirrorDisk right ???

THANKS,
derek h.

Halili,

You have MirrorUX installed. It is probably installed from HPUX11i Enterprise OE or Mission Critical OE. And your logical volume is also mirrored.

[f. halili]

yes we have on one machine

HPUX11i-OE-MC B.11.11.0203

and on another

HPUX11i-OE-Ent B.11.11.0203

THANKS!

[f. halili]
