If you have set set asm_diskstring parameter to correct value i.e, something like /dev/rhd* (in case of emcpowerpath) the disks should be visible to you.

If still the disks are not getting shown please check Metalink note 1174604.1 “ASM Is Not Detecting EMC PowerPath Raw Devices Or Regular Raw Devices On AIX” as there could be some permissions issue.

Thanks for pointing it.

You can use soft links but oracle recommend's using mknod to create link. You can use following code to increment disk#


for i in 1960 20CD 20CE 20CF 21CD 21CE
do
j=`pcmpath query device|grep -p $i"$"|grep DEVICE|awk -F ":" '{print $3}'|awk '{print $1}`
k=`bootinfo -s $j`
a=`ls -la /dev/$j |awk '{print $5}'|awk -F "," '{print $1}'`
b=`ls -la /dev/$j |awk '{print $6}'`
b=`echo $b |awk '{x=$0+0; print x}'`
if [ b -le 1 ]
then
b=`ls -la /dev/$j |awk '{print $5}'|awk -F "," '{print $2}'`
fi
if [ m -le 8 ]
then
m=`expr $m + 1` ;echo "mknod /dev/asm_disk0"$m "c "$a $b
else
m=`expr $m + 1` ;echo "mknod /dev/asm_disk"$m "c "$a $b
fi
done

(these two should be the same)
mknod /dev/asm_disk1 c 21 4
ln rhdisk4 asm_disk1

If you can find a way to increment the disk # easily, you would be golden and it would save a few lines
