symdg used in importvg script

Hi,
We have the following script which fail from the begining doing nothing:

1 echo "getting and activate disks from $DG group"
2 for DG in `$PATH_SYMCLI/symdg list|grep PR1_|awk '{print $1}'`
3 do
4 echo "Activate disks from $DG"
5 for DISCO in `$PATH_SYMCLI/symdg show $DG|grep "dev/"|cut -f2 -dr|awk '{print $1}'`
6 do
7 /usr/sbin/chdev -l $DISCO -a pv=yes
8 done
9 done
10 #
11 # Import Volume group
12 #
13 #for VGNAME in `ssh pr1dbci1 lsvg|grep vgpr1sap`
14 for VGNAME in `ssh pr1dbci1 lsvg -o|grep vgpr1sap`
15 do
16 DISCO=`ssh pr1dbci1 lspv |grep "$VGNAME "|head -1|awk '{print $2}'`
17 echo "Import VG: $VGNAME $DISCO"
18 /usr/sbin/importvg -y $VGNAME $DISCO
19 done

Now a sample output from one of failing DG (PR1_SAPDATA):
Standard (STD) Devices (168):
{
--------------------------------------------------------------------
Sym Cap
LdevName PdevName Dev Att. Sts (MB)
--------------------------------------------------------------------
DEV001 N/A 0001 (M) RW 22013
DEV002 N/A 0004 (M) RW 22013
DEV003 N/A 0007 (M) RW 22013
DEV004 N/A 000A (M) RW 22013
}

BCV Devices Locally-associated (168):
{
--------------------------------------------------------------------
Sym Cap
LdevName PdevName Dev Att. Sts (MB)
--------------------------------------------------------------------
BCV007 N/A 0652 (M) RW 22013
BCV008 N/A 0655 (M) RW 22013
BCV009 N/A 0658 (M) RW 22013
BCV010 N/A 065B (M) RW 22013

The script it was working ok untill last week, and in previous log file I can look output for each disk, like hdisk286... In PdevName column it used to be the devices names like this: /dev/rhdisk286... but now it shows like N/A. We noticed that now we got some PVMISSING devices when trying to varyonvg.

I'd appreciate your help.

Thanks,
