The chvg command does not support use in volume groups varied onin enhanced concurrent mode. If you want to increase the size of a shared LUNallocated to your cluster, follow this process:1. Bring the volume group offline (stop the cluster on all nodes).2. On the first cluster node: a. Run cfgmgr b.

The purp.. 더보기 Understanding_active_and_passive_varyon_in_enhanced_concurrent_mode An enhanced concurrent volume group can be made active on the node, or varied on, in two states: active or passive. Note that active or passive state varyons are done automatically by HACMP upon detection of the enhanced concurrent mode volume group, based on the state of the volume group and current cluster configuration. Important: All nodes in the cluster must be available before making any L.. 더보기 Fast_disk_takeover Failed volume groups are taken over faster than in previous releases of HACMP™ due to the improved disk takeover mechanism. HACMP automatically detects all volume groups and ensures that the faster option for volume group takeover is launched in the event of a node failure. This functionality is especially useful for fallover of volume groups made up of a large number of disks. Note: Fast disk t.. 더보기 Enhanced_concurrent_mode AIX® provides a new form of concurrent mode: enhanced concurrent mode. In enhanced concurrent mode, the instances of the Concurrent Logical Volume Manager (CLVM) coordinate changes between nodes through the Group Services component of the Reliable Scalable Cluster Technology (RSCT) facility in AIX. Group Services protocols flow over the communications links between the cluster nodes.
