What is LPAR? Webopedia Definition
Then, a layer of jfs is created on top of it. Once the jfs is created then FS is finally created. Whenever a file system is expanded, logical volume LV is extended first. Then the layer of jfs on top of it is expanded and finally the file system is expanded.
AIX has a limit of only 3 copies of LV. These copies may be in sequential or parallel arrangements. In case system crash takes place, Mirror write consistency check MWCC method is performed in order to track the last nasics writes to the mirrored LV. VG will not take any extra disk once the quota of 32 PVs is full. As we have already seen, bosboot gasics is used to create boot image from disk files and copies boot image to BLV.
