If you upgraded to PowerHA 6.1 SP09, and if you have concurrent VGs, you may encounter this kind of error :
WARNING: Volume group VG1 is an enhanced concurrent mode volume group used as a serial resource, but the LVM level on node node1 does not support fast disk takeover WARNING: Volume group VG1 is an enhanced concurrent mode volume group used as a serial resource, but the LVM level on node node2 does not support fast disk takeover
in that case you need to apply efix IV27674 :
# emgr -l ID STATE LABEL INSTALL TIME ABSTRACT === ===== ========== ================== ====================================== 1 S IV27674sp9 11/15/12 11:34:00 verify fails w/ fast disk takeover
–> Don’t be too hasty to apply the latest Service Pack, you may have new bugs you didn’t expect

Hi, thanks for the tip, I had to face this bug but I could not find this efix, where did you download it from ? There is not download link on the APAR page.
Meanwhile, I debugged the cl_queryvg script and by comparing it with the previous version, I have fixed the code manually : the error is due to a wrong return code handling on line 419.
wrong line :
if /usr/sbin/lqueryvg -p ${PVOL} -X
correct line :
if ! /usr/sbin/lqueryvg -p ${PVOL} -X
Hi Fabrice and thanks for the tip too
The efix was provided to us by the IBM support team… I guess it’ll be released soon .
I checked your wrong line, and it seems they modified it :
############################################################################### # -X Get volume group mode. ############################################################################### if [[ ${XARG} == true ]] then # Check if OK to access physical volume. get_vg_state if (( ${?} == 0 )) then get_vg_mode else /usr/sbin/lqueryvg -p ${PVOL} -X if (( $? != 0)) then get_vg_mode fi fi fiThanks for sharing !
