Mirror UX

[Amiel Tutolo]

I have a very simple question and I have probably read the answer in other postings and just do not realize it so here it goes. My manager purchased an L3000 from a broker and it is supposed to have the os already mirrored. How can I tell for sure that it is? If it isn't I want to mirror it and I have found those answers already. Thanks

First do a vgdisplay -v /dev/vg00 and note all the LVOL's. Next do an lvdisplay /dev/vg00/lvolxx for each LVOL and check to see that Mirror Copies is 1 (or more).

if you want to check.... you can check two things:

1. run the following to see if MirrorUX is installed... without it you will not have HP-UX mirrored

swlist | grep Mirror

2. On the root volume group, check for a mirrored logical volume 1 (lvol1)

lvdisplay -v /dev/vg00/lvol1 | more

make sure you pipe it to more or info will scroll off screen. Look for the "Mirror Copies" line and if it is 1 or higher, mirroring exists... if it is 0 then it is not.

Hi,

The easiest way is by doing:

First is to use 'lvdisplay -v /dev/vg00' and look for the mirrored copies row. If it reports 1 or more than it is mirrored. Also

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (0/0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/0/3/0.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0
/dev/dsk/c2t6d0
Root: lvol3 on: /dev/dsk/c0t6d0
/dev/dsk/c2t6d0
Swap: lvol2 on: /dev/dsk/c0t6d0
/dev/dsk/c2t6d0
Dump: lvol2 on: /dev/dsk/c0t6d0, 0

And thirdly, if on both of your disks that you have you can run 'lifls /dev/dsk/cxtydz' if it reports having HPUX listed, the volume can be booted.
