Error description
multibos -V varies on volume groups so it can verify they are valid. The volume groups are varied back off and the filesystems remain in /etc/filesystems. If the varyonvg fails the logical volumes with that volume group are removed. A standby volume group on a standby HACMP client will fall into this category. In an HACMP Cluster on a Volume Group that is varied on as concurrent Active/Passive, the Passive node will show the volume group as not varied on, multibos will do a varyonvg on the volume group, knocking out the Active node. This can show up as Reservation Conflicts. In a non-HACMP environment with concurrent volume groups when multibos does the varyonvg it will block out all the other nodes placing locks on the volume group.
Local fix
Problem summary
The mbverify function of multibos -V option during boot clears out defunct stanzas in /etc/filesystems. For filesystems on varied off volume groups the volume groups are varied on and their filesystems checked against /etc/filesystems. If a system is part of High Availability setup and contains concurrent volume groups the act of varying on and off may affect the HA UP status.
Problem conclusion
This change checks for concurrent volume groups on a system and if found will not setup the mbverify multibos -V call in /etc/inittab.
