Following are examples of creating and using mirror pools with physical volumes of a Volume Group. The right amine choice helps to reduce foam defects and can highly influence the physical characteristics and quality of the final foam. We offer traditional amines such as DABCO® 33 LV, a well-known gel catalyst for flexible slabstock applications, or DABCO® T, a reactive, medium active balance amine catalyst for rigid foam applications.

Since the use of mirror pools is optional with Mirror Pool Strictness set to ‘no‘, it is possible to create a mirrored LV, in which one copy is in one of the mirror pools, but the second copy is not assigned to a mirror pool:
In the illustration above we can see three LVs. The blue LV contains three LPs, each of which is assigned a PP on a different PV. Each of those PPs is in fact a copy; in AIX terms this LV is said to be singly mirrored. In this case the data storage capacity of the LV is determined by the number of LPs, so this will be a 3 GB LV, however, it will

Abstract. When moving or making a copy of logical volume data, the user can choose between migrating or mirroring. This article explains what to consider when choosing between migrating or mirroring. Content. The migratepv and mirrorvg commands may seem distinct, but the migratepv is simply a combination of the mirrorvg/unmirrorvg commands. Mirror pools are new to AIX beginning with 6100-02 and are only available for use in Scalable Volume Groups. Following are examples of creating and using mirror pools with physical volumes of a Volume Group.
The mirrorvg command takes all the logical volumes on a given volume group and mirrors those logical volumes. This same functionality may also be accomplished manually if you execute the mklvcopy command for each individual logical volume in a volume group.
The migratepv command moves allocated physical partitions and the data they contain from the SourcePhysicalVolume to one or more other physical volumes.LP represents a mirrored copy of a PP. Up to two copies of a PP can be mirrored resulting in a LP count of three (2 mirrors plus original). Volume Group Descriptor Area (VGDA) Information about all the LVs and PVs within a VG.
