Details:
Prior to VERITAS Volume Manager (VxVM) 3.x, there were no commands available to allow viewing the percentage of completion of a plex resynchronization or plex attach (atomic copy)

Below is a script that can be added to the system to enable finding out approximately what that percentage of completion is.

1) Enter the following script and name it vxpercent.sh  

#!/usr/bin/ksh
vxprint  $@ |
while read line; do
echo $line | read tag plex vol kstate len off state tutil putil
if [ X$tag = X"pl" -a X$tutil = X"ATT" ]; then
offset=$(vxtrace -t 1 $plex | tail -1 | cut -f9 -d" ")
percent=$(( 100 * 0$offset / $len ))
echo "$line" | sed "s/ATT     /ATT $percent%\ /"
else
if [ X$tag = X"v" -a X$state = X"SYNC" ]; then
offset=$(vxprint -l $plex | grep flags | sed "s/.*offset=\([0-9][0-9]*\).*
/\1/")
percent=$(( 100 * 0$offset / $len ))
echo "$line" | sed "s/SYNC    /SYNC $percent%/"
else
echo "$line"
fi
fi;
done;

2) If given no options the script will list all of the volumes.

When using the vxpercent.sh <volume name> syntax, an output similar to the following will be seen:

# vxpercent.sh testvol

Disk group: clarii0n

TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
v  testvol      fsgen        ENABLED  12582912 -        ACTIVE   ATT1    -
pl testvol-01   testvol      ENABLED  12593568 -        ACTIVE   -       -
sd clarii009-01 testvol-01   ENABLED  3148320  0        -        -       -
sd clarii010-01 testvol-01   ENABLED  3148320  0        -        -       -
sd clarii001-01 testvol-01   ENABLED  3148320  0        -        -       -
sd clarii002-01 testvol-01   ENABLED  3148320  0        -        -       -
pl testvol-02   testvol      ENABLED  12593568 -        TEMPRMSD ATT 39% -
sd clarii007-02 testvol-02   ENABLED  3148320  0        -        -       -
sd clarii003-02 testvol-02   ENABLED  3148320  0        -        -       -
sd clarii004-02 testvol-02   ENABLED  3148320  0        -        -       -
sd clarii005-02 testvol-02   ENABLED  3148320  0        -        -       -

In the above example it is shown that plex testvol-02 is 39% completed.

NOTE: In VxVM 3.x, the vxtask (1m) command provides extended information and control over resync and recovery processes.
