node1:/root # /usr/es/sbin/cluster/sbin/cl_reducevg -cspoc -n'node1,node2' -R'node1' myconcurrentvg hdisk29 cl_reducevg: Operation is not allowed because hdhegbgggghhgbhcgfhggh is a RAID concurrent volume group.
what the … ? what’s this « hdhegbgggghhgbhcgfhggh » name ?? I asked for [myconcurrentvg], not this weird name which came out of nowhere…
After digging a little bit, I found nothing in the ODM.
IBM told me that the weird name is a « translated » name from the internal PowerHA base , and is not aimed to be visible to a user; its is only used by PowerHA. So it’s not a bug. End of story :p
