Managing shared LVM components in a concurrent access environment
There are a few different steps for managing a shared LVM components in a concurrent access environment using the C-SPOC facility compared to managing a non-concurrent access environment. However, most of the steps are done in exactly the same order and using exactly the same SMIT panels as a non-concurrent configuration.
You can define concurrent access volume groups and logical volumes on all the disk devices supported by the PowerHA® SystemMirror® software.
Note: You
cannot define file systems on a concurrent access volume group unless
it is an enhanced concurrent mode volume group used as a serial resource.
Most maintenance tasks can be performed using the PowerHA SystemMirror C-SPOC utility. All operations for maintaining concurrent volume groups and logical volumes are done in exactly the same order and using exactly the same SMIT panels as non-concurrent configuration.
