Evadiscovery fails

[Pacek Maciej]

Hi i try to setup Metropolitan cluster and when I am runing evadiscovery i get an error:
evadiscovery -f /etc/dtsconf/mceva.conf
/usr/lib/dld.sl: Unresolved symbol: __tcerr (data) from /opt/wbem/lib/libpegcommon.1
Abort(coredump)

Shalom,

Take a look a the evadiscovery command with the chatr commmand.

You may find that some of the libraries it requires are not installed. This should not happen but it happened to me the other day on a cold install.

You'll need to make sure the libraries the program needs and make sure they are on the SHLIB_PATH

Then the command should work just fine.

pdbsrv01:/#/usr/bin/chatr /usr/sbin/evadiscovery
/usr/sbin/evadiscovery:
shared executable
shared library dynamic path search:
SHLIB_PATH enabled first
embedded path enabled second /opt/wbem/lib
shared library list:
dynamic /usr/lib/libpthread.1
dynamic /usr/lib/librt.2
dynamic /opt/wbem/PA/A.02.00.04/lib/libpegclient.1
dynamic /usr/lib/libm.2
dynamic /usr/lib/libcl.2
dynamic /usr/lib/libc.2
static /usr/lib/libdld.2

I have found all libraries, still evadicovery fails with the same error.

Fascinating,

Try removing and reinstalling the evadiscovery software. Make sure the OS is properly patched prior to installation.

Hmm, I have neve seen this fail like this.
Isuggest you verify you have the required software versions and any patches for the OS, Serviceguard, and WBEM, and also make sure you have the relevant paths to shared libraries configured correctly.
If that does not help, log a callwith your local HP Response Centre

This is a known problem. It will most likely be fixed in a patch for Metrocluster/EVA.

Use the LD_PRELOAD option while invoking the evadiscovery command.
e.g.: LD_PRELOAD="/usr/lib/libC.2 /opt/wbem/lib/libpegclient.1" evadiscovery -f /home/mceva.conf

(all in one line!)

Also modify the script "/usr/sbin/DRCheckDiskStatus" to include the LD_PRELOAD option wherever DRCheckCAEVADevGrp called.
eg:
if (( $cvmisused == 0 ))
then
LD_PRELOAD="/usr/lib/libC.2 /opt/wbem/lib/libpegclient.1" DRCheck${dataRep}DevGrp $ENV_FILE $lvmisused $vxvmisused "`echo ${LVM_VG[@]}`" "`echo ${VXVM_VG[@]}`"
else
LD_PRELOAD="/usr/lib/libC.2 /opt/wbem/lib/libpegclient.1" DRCheck${dataRep}DevGrp $ENV_FILE $lvmisused $vxvmisused $cvmisused "`echo ${LVM_VG[@]}`" "`echo ${VXVM_VG[@]}`" "`echo ${CVM_VG[@]}`"
fi


This problem will happen only in WBEM Services versions A.02.00.09 or later. It does not show up in earlier versions. Downgrading WBEM might also be an option.
