Oracle Database - Enterprise Edition - Version 10.2.0.1 to 11.2.0.3 [Release 10.2 to 11.2]Information in this document applies to any platform.
PURPOSE
kfed is a useful tool which allows to analyze ASM disk header information when ASM diskgroups can not be mounted. As the number of ASM devices for a diskgroup increase, sometimes it's very hard to anlayze all devices without eye-balling each kfed output for all ASM devices, which is time consuming and error prone. kfed.pl is a simple perl script which displays gist information such digkgroup, diskname etc in one line for each ASM device from the kfed output.
kfed.pl is particulary useful for diskgroup mount issue due to the following errors :
- ORA-15042 : ASM disk \"%s\" is missing from group number \"%s\"
- ORA-15020 : discovered duplicate ASM disk \"%s\"
- ORA-15033 : disk '%s' belongs to diskgroup \"%s\""
- v$asm_disk shows disks with "MISSING", "IGNORED".
- v$asm_disk shows disks with "PROVISIONED status while the diskgrop is mounted.
REQUIREMENTS
kfed output for all ASM devices
1-1. Build "kfed" executable if it does not exist. kfed executable comes with installation from 11.1 onwards.
$cd $ORACLE_HOME/rdbms/lib
$make -f ins_rdbms.mk ikfed
1-2. As root,
- cd <asm home>/bin and create a shell file called kfed.sh using the following script
- And change the permission as executable - ex) chmod 755 kfed.sh
- /dev/mapper/* on 3rd line should be replaced with ASM devices path on the server before running kfed.sh
kfed.sh
rm /tmp/kfed_DH.out /tmp/kfed_FS.out /tmp/kfed_BK.out /tmp/kfed_FD.out /tmp/kfed_DD.out
for i in `ls /dev/mapper/*`
do
echo $i >> /tmp/kfed_DH.out
./kfed read $i >> /tmp/kfed_DH.out
echo $i >> /tmp/kfed_FS.out
./kfed read $i blkn=1 >> /tmp/kfed_FS.out
echo $i >> /tmp/kfed_BK.out
./kfed read $i aun=1 blkn=254 >> /tmp/kfed_BK.out
echo $i >> /tmp/kfed_FD.out
./kfed read $i aun=2 blkn=1 >> /tmp/kfed_FD.out
echo $i >> /tmp/kfed_DD.out
./kfed read $i aun=2 blkn=2 >> /tmp/kfed_DD.out
done
- Run kfed.sh in <asm home>/bin
# kfed.sh
- This will generate kfed output files in /tmp.
. /tmp/kfed_DH.out, /tmp/kfed_FS.out, /tmp/kfed_BK.out, /tmp/kfed_FD.out and /tmp/kfed_DD.out
CONFIGURING
Perl interpreter should be installed on the server - perl executable comes with Unix or Linux as default.
$ which perl
/usr/bin/perl
If perl executable is not found /usr/bin directory, the one in $ORACLE_HOME/perl/bin can be used.
$ export PATH=$ORACLE_HOME/perl/bin:$PATH
INSTRUCTIONS
Save the perl script at end of this note as "kfed.pl" and change the permission for execution.

SAMPLE OUTPUT
$ kfed.pl /tmp/kfed_DH.out | sort - t ' ' -k 2.3 > /tmp/kfed.out
- Check kfed.out if there is any missing disks from the diskgroup in question and work with System administrator team to find them.
- Check kfed.out if there is any duplicated disks in terms of disk number from the diskgroup in question, see note - 1299866.1.
- Or upload /tmp/kfed.out for Oracle support's review.
