Excactly. Your listing looks like this:

Code:

LP    PP1  PV1               PP2  PV2               PP3  PV3
0001  0111 hdisk0            0056 hdisk1            
0002  0111 hdisk1            0056 hdisk2            
0003  0111 hdisk2            0056 hdisk3            
0004  0111 hdisk3            0056 hdisk4

What you look for are lines like these:

Code:

LP    PP1  PV1               PP2  PV2               PP3  PV3
[...]
nnnn  xxxx hdisk31           yyyy hdisk3
nnnn  xxxx hdisk3            yyyy hdisk31
nnnn  xxxx hdisk3            yyyy hdisk3
nnnn  xxxx hdisk31           yyyy hdisk31

I didn't bother to build it but a little sed/awk/grep-filtering should do the trick nicely.

Any of these would mean that you lost both copies of a certain LP and thus data. In this case you will need to restore the respective LV from backup no matter what. You need to verify of this being the case first, because you will not be able to remove the missing disks with the method i described otherwise.

I hope this helps.

unicode_start

UNICODE_START(1)					      General Commands Manual						  UNICODE_START(1)

NAME

       unicode_start - put keyboard and console in unicode mode

SYNOPSIS

       unicode_start [font [umap]]

DESCRIPTION

       The unicode_start command will put the keyboard and console into Unicode (UTF-8) mode.

       For  the  keyboard  this  means that one can attach 16-bit U+xxxx values to keyboard keys using loadkeys(1), and have these appear as UTF-8
       input to user programs.	Also, that one can type hexadecimal Alt-xxxx using the numeric keypad, and again produce UTF-8.

       For the console this means that the kernel expects UTF-8 output from user programs, and displays the output accordingly.

       The parameter font is a font that is loaded. It should have a built-in Unicode map, or, if it hasn't, such a map can be given explicitly as
       second parameter.  When no font was specified, the current font is kept.

NOTE

       Unicode mode is a parameter with a value per virtual console.  However, usually the font and keymap is common to all consoles.

SEE ALSO

       dumpkeys(1), kbd_mode(1), loadkeys(1), unicode_stop(1), utf-8(7), setfont(8)
